Blow power cable

Q: Blow power cable

So I just had one that I have never seen before. My cable from the PSU to the surge protector just blew. Heard a pop and my PC died. Heart sank, then went about looking over the PC was going to call it a night and deal with it tomorrow when I unplugged the cable from the outlet to be sure the PSU had no juice going too it and I noticed the cable near the outlet (3 prong male end) had a big split in it right at the base near the plug. Switched to another cable and PC is up.

So the question is, what would cause this? The surge strip is fine (its a decent APC I forget the rating off hand). The surge protector never went out. Monitor, speakers and the phone charge plugged into it stayed functional. Did not have to reset the surge strip. The power cable was a bit old, maybe 7-10 years.. not the one that came with the PSU (3 year old EVGA 650 watt Gold rated). PC appears to be running fine. Should I be worried about the PSU or the surge strip? Any thoughts? Did the cable itself just blow.

For reference its a built i7 5820K Asus X99-A USB 3.1, EVGA GTX 970, Corsair PC 2400 memory, 2 samsung EVO 850 SSD's with a Corsair H115i cooler. EVGA 650w Gold PSU.

Any thoughts greatly appreciated

i custom builted my pc in hong kong, the chasis i purchased isn't very study, in fact i's quite cheap, anywho i've noticed a very serious problem with the power button on the front of my pc.

the power button itself is about the size of a thumb, but what's so bad about it is that it's too sensitive.

i've never noticed it before, but this morning when i turned on my pc, i only *touch* the button lightly, and BOOM my pc powers on, i didn't even push the button all the way in, i just touch it and my pc is already on, now to me this is very serious and worries me quite alot.
i'm worry that my pc might fry becasue of it, i had an old hp, i rememebr when i push the power button once but my hands were abit shaky so when i push the button once, the button was actually pushed twice causing the pc to rapidly turn on and off then back on again, then before i know it my hp fried up and was dead, it was unrepaiable.
now i'm worried that the sam thing might happen again on my new pc, if the button is so sensitive, if my hands got shaky again when i push it won't my new pc fried like my old hp?

i have a very cheap psu, and that makes things worst and me more worried, below is my pc spec:

PSU 250 watts

I recently built myself a new computer because my previous one was at least 7 years old. Though I only bought one GPU for now, I wanted the option to upgrade to CrossFire later on so I bought an 800W Power Supply from ABS, since those HD 2900XTs are very power hungry in overdrive. My computer was working great for the first 5 days, but then after gaming for about 2 hours one evening my computer just died. When I attempted to turn it back on all I would get is a brief flash of the LEDs on my fans, but nothing else. I tried everything, leaving it alone, unplugging it for a while, it won't do anything but flash the LEDs on my fans and then shut off.

I still had my old computer, but the the power supply in my old one was only a 20 pin connector and my new motherboard was a 24 pin connector so it wasn't as easy as just replacing the power supply and checking if my new PC booted up. I first tried putting the new 800W PSU I just bought in my old one and I got the same result, the fan LEDs flashed and nothing else happened. I then tested all the fans in my new case by connecting them to my old PC and they all worked fine. At this point I am pretty confident it is the power supply casuing the problem, but I don't know for sure whether I caused it to fail or if it was defective. Is it easy to overheat a power supply? I have a Xion Onyx Case with an extra 80mm fan added on the side, giving it 4 fans total. The hottest thing in my case would be my GPU, which has peaked at... Read more

A:Did I blow my power supply or was it defective?

Your graphics card does seem a little hot.... but it is a new ATI and i'm not sure what the temps for them are (i have a geforce 8800 GTS 50 idle 75 max).

To me just sounds like a failed PSU but i can't think of any reason why. It shouldn't be heat and it sounds pleanty powerfull enought to power the card so I would just RMA it (if it's still under warranty) and get a replacement.

Good luck

I did a search on this site to see what other people did when there PSU was having similar problems to mine. I ruled out that indeed it was the PSU, but using a tube so I could listen to where the source of the noise was coming from. So what I did was buy another PSU, I have a HP pavillion 753c ( i know ick, but it was a gift when I was in high shcool) I had a Bestec ATX-1956D B2 (0950-4106, 200W) - (atx1956d), and I figured I had to get one that was compatible, so I replaced it with a 200W micro ATX PS3 Power Supply. New PSU info link.
After the new PSU was install I turned the computer on and experienced the same problem, the noise was yet again coming from my PSU. Here is the catch though if I tap my hand on the back of the PSU fan from outside of the case it will stop making that noise, but the second I reboot it starts making that noise again. I dont believe two different PSU could be causing the same problem but yet when i listen it is coming directly from the PSU fan. Any ideas?
ANother question I wanted to ask is, is it possible for me to get any type of PSU which is supported by a P4.

A:Power Supply makes blow dryer whiste/grind noise

Are you sure it's not either a wire dragging on the CPU fan, or the CPU fan itself? Do you have any other fans in the case?

I'm having a bizarre issue where simply unplugging the official Lenovo power supply from the orange USB power port causes the laptop to immediately issue the subject warning, along with the detail "A USB device has malfunctioned and exceeded the power limits of its hub port".   This warning pops up every 5 seconds, unless clicked on, where reset/close options do nothing.  Crazy thing is, NOTHING is plugged into any USB port!   Reattaching the power supply does not clear the error.  Only rebooting with the power supply cable connected clears the error.   Remove the power cable, and the error instantly comes back.   All of the USB ports actually work fine, including the USB C port, whether or not this message is active. Maybe it is a hardware issue, but ALL the USB ports actually work fine.  I can't figure how unpluging the power source can trigger a USB power surge when nothing is actually connected and the battery is fully charged.  I've removed/reinstalled the USB Root hub, eXtensible Host Controller, Generic USB Hub, etc., drivers multiple times to no avail.   No errors with any devices are apparent in the device manager. I've seen a lot of issues reported about USB power surges but none like mine.   Anyone have any ideas about this?  System: Lenovo Yoga 900/16GB/Windows 10

hi all,

I'm in a bind, and a friend referred me to this site, where I might be able to find some decent answers.

I run a small computer store in my hometown, and I was fixing a Sony Vaio PCG-FRV35 Notebook, It's fairly old, p4 with 512mb ram... But anyway, I was just removing spyware and viruses from it, and finished that up, then he said his sound wouldnt play, i started by reinstalling drivers and all that good stuff but it didnt play, I decided to lookinto the notebook to see if the speaker wires were connected and everything was fine there...

I pried off the faceplate for the powerbutton and LEDs and everything thats just above the keyboard, and I saw a ribbon cable connecting the power button and speaker circuit board to the motherboard, so i carefully unhooked it and put it aside, after finding no problems I rehooked it back up and tried to turn on the computer again... no power no post no sound nothing. It's like the power button is shot now. I've troubleshooted for 3 hours already on it, tried a multimeter to check to circuit connections, tried _everything_

I have no idea what to do now, this guy want's his laptop so he can work with it, and I dont feel like having to replace a laptop... this is like a techs worst nightmare >_<

Any advice would be greatly appreciated, is there any known issues were these power ribbons?

I have a ECS P4.945GCT-M/1333 (3.0) 775 mATX Motherboard and I installed Intel E2180 cpu and put memory stick on it. The computer won't boot - the cpu fan moved a second when I plugged in the power, and the stopped. If I disconnect the auxillary power cable, the CPU fan just can start, but of course it won't post. If I also disconnect the cpu fan, the power supply fan starts and I can see keyboard lights turned on for a second.

I measured the power on auxillary cable and it is ok: 2 12v and 2 GND. I am pretty sure that the power supply is good: I put on another power supply there and it is the same thing.

I've got a computer that's turned off. I press the power switch, and nothing happens. Now, I unplug the network cable and the computer turns on.

Why does having a network cable connected prevent the computer's power switch from functioning? And why does unplugging the network cable cause it to power up?

The computer has worked fine for a year, but was recently moved to the other side of the room, and a new switch replaced the old network hub at the same time.

Hi guys
I have a problem with my medion mt6 desktop pc.
While running a game i accidently dislodged the power cable and now when i press the button the screen recieves no signal.l also when i press the button again it powers down like ive pulled the plug. I have tried a new screen but no luck. Also the motherboard was recently replaced by medion but it worked fine for about 2 weeks. What is wrong and is it software or hardware?

A:Computer won't power on after pulling out power cable

You need to go into 'device manager' (which is a part of your Windows program). Click 'start menu': choose 'Help and Support' icon. Type 'device manager' in the 'search box'..print out the instructions. If you are new to troubleshooting your computer: print all instructions. It will save you a lot of time and mistakes. Look at the device manager screen, click on 'monitor', then 'properties'. Next do the same on 'display adapters' This will tell what's not 'operating properly' and whether it's the driver's. 'Help & Support' has much help to offer...but not all the answers by a long shot. Good Luck.

After shutting down, my computer will not power-on again unless I unplug the power-cord, then plug it back in (or use the psu on/off switch).

I have tried changing PSU, same thing happens.

My guess it has to be related to my motherboard.
I have the latest bios. I have reset the bios.
This happened after upgrading to a opteron 180 cpu. But I'm not sure if its related.
I have tried disconnecting the RAM, harddrive, graphics card to no avail. Also tried refitting the power-button cables.
Computer is rock stable once its on ...It powers on fine if I switch off the PSU with the button that is located on the psu, or pull out the power-cable before turning it on.

Any ideas what might be causing this?
Epox 9npa+ultra motherboard, amd opteron 180 (939), win xp sp3, 2gb ram

A:computer will not power-on unless I unplug power cable first

Unplugging the power supply, or disconnecting from the source allows everything to reset in the power supply and on the motherboard. This situation is most always associated with a defective power supply.

Since you have changed the power supply and the condition persists then the problem almost has to be a fault in the motherboard POWER GOOD circuitry.

If it were my machine I would just get in the habit of turning off the power supply after use, and live with it. Unless the problem is something obvious such as a "bulging" or leaking capacitor, chasing a problem like this is like chasing ghosts.

Hi, I have an Acer V3-772G which I have had from new (Semi New from Amazon, warehouse cosmetic damage), Have never experienced any issues with powering on/off/charging until recently. Here is where I am up to; Laptop will power up from the battery.Laptop will not power up with cable alone (Battery removed).When powered up with the batter inserted ? the laptop will (according to the battery monitor on the laptop) charge the battery, however, the battery continues to discharge and the laptop will eventually run out of charge.When the power cable is inserted whilst the laptop is powered up, the laptop recognises that the cable is connected and will enable the "Plugged in" power settings etc. If I then remove the battery, the laptop powers off.Laptop seemingly charges the battery when it is powered off, however, even after a full night plugged in the battery doesn?t have the charge to start the laptop.Both the external cable and the battery are in perfect working order (Having tested both with a separate Acer laptop).I have opened and cleaned all connectors / fan / CPU / GPU inside the laptop and nothing looks out of place.All USB / Optical Drive / HDMI ports ETC all work without issues. I?m assuming a cable issue and not a main board issue because there are no other faults besides the DC cable (Battery will still power the laptop etc.). I have ordered a replacement 120w internal DC cable from the spare parts website to test my theory. In the meanti... Read more

Hello everyone, I am new on this forum and I have an issue with my motherboard, the issue is as follow;
1- When I connect the 4 pin ATX 12v to the motherboard everything stop nothing works, the CPU fan stop working and everything else, The Motherboard brand is FOXCONN 865A01, even I change the Power supply and still have the same issue.

I would like if someone can show me the right direction on how to fix this issue.
Thank you in advance for any help someone can give me.


A:4 pin atx12v power cable causes power short

1. Welcome to Tech Support Guy
2. The usual cause of such an event is either
A. a defective motherboard - unlikely but could be
B. If this is a new build - a build error and the motherboard is shorting across a ground fault when that power is connected
C. You are using the wrong connector or connecting it on the incorrect orientation - eg the clip is not the correct way on the motherboard header
D. CPU error - bent pin on insertion of CPU

3. Please post some more detail of
is it new build
CPU details
What checks have you made if new build
Re 865A01 - which one please there are variants

4. I presume now having looked at the board it is NOT a new build, so when please did this first occur
and what problems were seen first, if any , before this
Most likely cause now, as I think the system is of some age is the board or the processor, if you refer to the 12v aux power

ATX 12V Power Connector: CN11
The 4 pin ATX 12V power supply connects to CN11 and provides power to the CPU.

Hi all,

I'm hoping for some help/advice with a problem I have with my laptop. One of the wires that attaches to the power jack keeps coming off and I was wondering if it was possible (and safe) to take the jack out of equation by wiring the power cable directly into the wires that lead out of the jack?

If so, is it likely to be fairly obvious which wires should be attached to each other?

Any advice would be greatfully received.

Hi Tony, and welcome to TSG.

Are you talking about a wire that goes from the motherboard to the jack? Many laptops have the jack attached directly to the motherboard.

If it is a wire from the jack to the motherboard, you might be a lot better off by finding a better way of attaching the wire to the jack so it doesn't come off.

USB 3 power cable
I just bought an "Inland" USB3 PCI Express card and installed it. For USB3 speeds, I believe it needs a 4 pin white power connector which is the same as a floppy power connector and I don't have one in my HP6200 Pro. One of my other PCS has one attached to a SATA connector and I could clip it and splice the 4 wires together onto one of the HP's SATA connector but it isn't my favorite task on a new PC. The card defaults to USB2 speeds but I already have 10 USB2 ports and would like the super speed for backups onto a USB3 ext. HD. Are there such adapters on the market, CABLES.com has hundreds of pages with very small pictures. The 2TBt Seagate EXT HD is AC Powered and I also wondered if it might already reach Super Speed. It doesn't seem so. BTW, Win8 found and supplied the drivers for the card, but then I installed the supplied mini CD USB3 drivers with no change. A techie in Micro Center said that w/o the separate 4 pin power connector, the card and ports will just function as USB2. Any thought?

A:Heating with power cable.

Yes, electrons moving around in a fast manner tends to produce a temperature raise.

Is there some kind of issue with using the machine that you're specifically trying to fix?

When you have it connected to the wall, the power plan changes and lets the machine work more to its abilities. When it is not connected to the wall, it changes certain things to not work as fast as possible (or things like dimming screen) so that power can be saved and battery life is extended so it doesn't need a recharge so soon.

What you're describing is normal operations.

You should never post your email address on a forum. Just opening yourself up for tons of spam.
At least put some spaces in the middle so real people will know to remove them before emailing you.

As for the 386, would you have a picture or link to the the support page, if it's still available?
or a picture of the power connector?

If it's an old 386 PC, then the only thing I could think of is maybe eBay.

I am connecting a new motherboard to my existing case and came to somewhat of a an impasse. Well, let me start with some info on my system:

Motherboard: ASUS M2A-VM AM2 Micro ATX (brand new)
Case: from an eMachines T3104 I had lying around (don't worry, though... I upgraded the PSU)
PSU: Thermaltake TR2-430W (brand new)

RAM: 2x1GB (Crucial DDR2 PC2-4200)
HD: Seagate Barracuda 250GB (7200RPM) IDE
Optical Drive: CD/DVD-ROM (IDE)

I also had to install an IDE port card on one of my PCI slots, since my motherboard only came with one IDE connector. I'm leaving that one for the CD/DVD-ROM and connecting the hard drive directly to the mobo.

All I need to connect now are the wires running from the front of the case to the motherboard. They are:

POWER SW: Black and White wires, with one single connector
H.D.D. LED: Red and White wires, with one single connector
POWER LED: Green and White wires, with one single connector

I read a thread here, in which someone (I think it was Tedster) said that the POWER SW can be connected anyway, without regard for positive or negative. Please correct me if I misunderstood the answer. As for the other cables, how do I find out which one is positive and which one is negative? My other problem is that the POWER LED cable has one si...

Hi, Th HP jack configuration (Beats Audio)), to the best of my knowledge, is standard. I also have a Soundblaster (SB) high end audio card with the same (similar) jack configuration. I am using a Bose speaker system with a subwoofer. The speakers attach to the subwoofer audio out jack. A cable connecting the audio out jack from the PC connects to an audio in jack on the subwoofer. The subwoofer powers the speakers and the subwoofer from an AC outlet. Since the Diamond speakers were connected to your Packard Bell PC as you have described, I see no possible way you will be able to connect those speakers to the HP PC you have purchased. There appears to be no way to provide power to the Diamond speakers from the HP PC or any PC I have used over the last ten years. BTW, I had a PB way back in 1996. VERY proprietary. Jaco   Jaco

I have a ASUS P6T mobo with a i7-950 CPU.The mobo has a 8 pin power cable connection for the CPU, but 4 of the pics are covers. Not 4 on one side, but 4 on one end.

I have the machine running, all is well, but I'm wondering if I should get an 8 pin cable and use that instead of the 4. I don't do any gaming or real heavy usage projects. A #2 pencil and a sheet of lined paper would do most of what I do.

I have looked on the ASUS forum but not found a positive answer one way or the other, maybe there isn't one.

I figured I'd post here since the knowledge level here seems to exceed any other forum.

Any info is appreciated.

A:Mobo/CPU power cable ?

All eight are not normally needed unless you've fitted an Extreme Edition
CPU which requires considerably more power...

My neighbour was given a second-hand computer and asked for my help setting it up.

It is a Dell Optiplex 755 running Win7.

Currently installed graphics is NVidia Quadro FX 3500.

I looked up the service tag and this is not the original card (Original was ATI HD2400XT).

The issue I have is that the FX3500 is an 80W card, with the PCI-E slot having a max of 75W. On booting I get low power warnings from the NVidia card.

The card has a 6 pin PCI-E connection available for the additional power, but the PSU has no PCI-E power cable.

The only free power cables from the PSU are a couple of 15pin SATA cables. I have seen adapter cables for 15pin SATA to 6 pin PCI-E. Are these any good for my situation?

If not, what are the alternatives? New PSU? Different GFX card?

A:Power adapter cable for PCI-E

Based on what you just told us, one of those adapter cables should work just fine.

I want to add another HDD to my Lenovo E73, I fitted the drive into the E73 and went to connect the spare connector that is on a black cable that goes from the motherboard and loops to HDD1 and my DVD drive.
But the spare connector is about an inch away from connecting to Hard Drive 2, does Lenovo stock a cable
that has a bit more slack in it or can anyone suggest a replacement ? I have seen suitable cables on Amazon that loop to 4 devices but unfotunately it needs a 4 pin connector to plug into the motherboard ? The Lenovo number on the cable is FRU 54Y8286.
Can anyone help please ?

A:E73: need power cable for adding second HDD

I have not seen a cable like that before, usually SATA power connects or is wired into the power supply directly.   
I'm thinking there is probably a longer Lenovo cable available, have you research the Hardware Maintenance manual for your system?     Alternatively, you could add a SATA power cable extension (that would add a connector in the path, and possibly more cable than you need.)

I have the 15ISK 80SM model, and the power cable is so short it's extremely limiting. Where can I get a longer one?

Quick question about power cables, 4 wires...Red1, Black2, Black3, Yellow4.
1 & 2 complete the circuit and 3 & 4 complete another circuit. I know more voltage flows through 3 & 4. I just wanted to know if someone knew the voltage across those to those 2 sets of points. I have 3 case fans, one originally came crimped into 1 & 2, but im going to splice into 3 & 4 because the other to are that way and they push alot more air. Also i did a test with a christmas light bulb and put it through 1 & 2 and it lit up like normal, 3 & 4 and it was blinding me.

I'm currently building a new system and I think I've made a pretty deadly mistake.

My NEW power supply has a 6/8 pin PCI-e cable that I accidentally plugged into my motherboard's 4/4 pin CPU power slot. I tried to boot up the system while they were incorrectly matched, and now the computer fails to boot up with the new power supply connected.

So I tried using an older power supply that I know for certain how to connect properly. Thankfully, the new system boots up just fine.

What happens now with the NEW power supply? Testing the old one confirmed that at least the motherboard and everything are still okay.

Do I have to replace the new power supply? It seems to work okay when hooked up to another system, just not with my new one.

you have to provide more info - motherboard make & model and PS make and model. At the least it sounds like MB is OK

Hi there form. I'm a newbie here, please be gentle.

My question is this: I recently moved and the power cable for my PC tower went missing during the move. I have a project due tomorrow that I must work on today. I have a power cable for a printer that I can use as a replacement, but the voltage of that cable is 125 volts, where as the voltage listed on the tower is 250 V. Will it harm the computer to use a cable with lower than required voltage? It's a rather old machine, I try to be kind to it.

Thank you in advance for your help

First time builder here. I have a Corsair CX430 power supply and EVGA GTX 970 video card. There is only one PCI-E power cable and two connectors on the card. Everytime I plug it in and try to boot up all I get is this message: "Please connect PCI-E power cable(s)." Do I need a different PSU?

A:GTX 970 power cable problems

Hi and welcome to TSG.

The CX series from Corsair are only really any use for basic builds using integrated graphics cards, as stated on Corsairs own website, they really aren't up to the job of running a standalone dedicated card.

The minimum PSU requirement for a GTX970, taken from the NVidia website is 500w and that should be a good quality 500w unit aswell, not a cheap one (it does make a significant difference). Personally, I would look at something around 650w from a manufacture like Corsair (HX, TX and AX models only), Seasonic, PC Power and Cooling or OCZ to name a few. Look for a PSU with at least 5 years warranty, preferably 7 or 10.

So I just had one that I have never seen before. My cable from the PSU to the surge protector just blew. Heard a pop and my PC died. Heart sank, then went about looking over the PC was going to call it a night and deal with it tomorrow when I unplugged the cable from the outlet to be sure the PSU had no juice going too it and I noticed the cable near the outlet (3 prong male end) had a big split in it right at the base near the plug. Switched to another cable and PC is up.

So the question is, what would cause this? The surge strip is fine (its a decent APC I forget the rating off hand). The surge protector never went out. Monitor, speakers and the phone charge plugged into it stayed functional. Did not have to reset the surge strip. The power cable was a bit old, maybe 7-10 years.. not the one that came with the PSU (3 year old EVGA 650 watt Gold rated). PC appears to be running fine. Should I be worried about the PSU or the surge strip? Any thoughts? Did the cable itself just blow.

For reference its a built i7 5820K Asus X99-A USB 3.1, EVGA GTX 970, Corsair PC 2400 memory, 2 samsung EVO 850 SSD's with a Corsair H115i cooler. EVGA 650w Gold PSU.

Any thoughts greatly appreciated

A:Blown power cable

It is possible it was partially defective and with age and dust was enough for the power to jump across, what voltage? You in US 120v OR eu 240v. I would think it would be more likely to jump 240v. I might have had a crack in the plastic with dust buildup. That is why they tell people to blow the dust out in their PC, can be conductive.
