New power supply, no schematic, looking for power fan plug.

Q: New power supply, no schematic, looking for power fan plug.

Finally broke down and started building a new system -
I'm too old to game, this all started out as a home video
project.

Anyway - gathered all my components, now I'm working
to assemble them.

The case came with an Okia Model 500-ATX power supply.
But no wiring schematic.

I'm trying to identify the power supply fan plug - what seems
to be it doesn't at all match the connector on the board.
And I've got that positively identified by the board manual.

The board has a small male 3 pin connection. The only thing I
can find that might be the fan connector coming from the
supply is a small 4 pin plug at the end of 1 of the strings of
drive power harnesses. Nothing tucked up behind the
supply case or anything.

Is that likely to be it? Or would that be for a floppy or something?

I tried to Google for a wiring schematic, but could find nothing.
In fact, nothing much at all on this brand of supply - just
a couple places that sell them. Please don't tell me I got
an el cheapo that isn't worth having!

At the risk of getting ahead of myself, in case I need to adapt
something like that to the different style male connector on the
board, in this case or something else I may find as i progress,
is there some type of source for adapters, or what would I do?

Bear with me, this probly won't be the last question I'll dream up -
just getting started.

While I'm at it - the board manual talks about a connector
for a power supply that senses board temps - that's another reason
I'd like to find a schematic or some sort of instructions for the power supply.

OH! The connectors for the 2 fans in the case don't match the connector
on the board, either. The board has another small male 3 pin connector
for the case fan(s), but these have a larger, bigger pin, 4 pin connector.
Again - I suppose it's adapter time? Guess I'll need that source!

Thanks for helping an "old" computer student still (and probly always)
in a definite learning curve!

Preferred Solution: New power supply, no schematic, looking for power fan plug.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: New power supply, no schematic, looking for power fan plug.

There are basically two voltages available to you: 5V and 12V. Doesn't really matter where you get it from - some pin on the mobo or some wire from the PSU.

From the PSU the yellow wires are 12V and red ones 5V, black is ground. The fan voltages should be written on the fan itself, the black fan wire is ground, red may be 12V or 5V depending on the fan voltage.

Fan headers on the motherboard should be labelled so, check with a voltmeter what pin gives out what.

Sorry I don't know the proper terms, but basically the pin inside the jack where the power cord gets plugged into on my laptop was bent so that it's really hard for me to plug in my power cord and have it stay in place. My warranty with best buy has expired, so I need to figure out how to solve this problem on my own. I can't just leave it like this because the cord comes out really easily and I can't continue to work with such a tenuous setup. Anyway, is this just a matter of replacing the entire unit inside my laptop? I know you probably need more information, but I'm not sure what to provide, so please ask any questions. The laptop is a Toshia M-45, about 3-4 years old. Thanks in advance

My son's Lenovo Notebook's power supply plug doesn't work anymore, and he has only had it for 2 years. He bought one of the newest and most powerful ones, and thus a very expensive version i.e. a bit above 1,000.00 UK pounds. The same happened to my Lenovo tablet. Two years after I bought it the power supply plug went dead. I manage to make it work again about 3 weeks by replacing the cord, but then it died again despite trying with 6 different cords. I have also tried to blow clean the plug with a can of pressure air. Didn't help. After googling the issue I can see many Lenovo customers have the same problem, and that it has been going on and on since 2011 perhaps even earlier. So I assume Lenovo has addressed and solved the problem by now. I went back to the vendor with my tablet to have it repaired, and the response was that it would be too expensive to repair, and that I would be better off buying a new tablet. So I did. Do you think I bought another Lenovo? Of course not! We are never gonna buy any Lenovo products ever again. I still have the old tablet, though, and would be very happy if could be repaired. The same applies to my son's portable pc, he needs it for school projects, so it is quite urgent that his pc can function again asap. What are you, Lenovo, going to do to help us out with these problems? Sincerely Yours, Anna Maria Lassen PS Who has written 'What is DOS' right under my name in the top of this message?

Welcome to the Lenovo Community !
 
Doing charge cycles of full to empty can be hard on a laptop battery.  If you are going to have the laptop plugged in and you will be working on it for a extended period of time then why not take advantage of the Conservation Mode option that the Lenovo Settings app has to offer.  With the Conservation Mode enabled it will maintain your battery's charge in the 55 to 60% range rather than continually charging it to 100%.  This will help extend the overall life of the battery.  In the event you can foresee the need to go portable then switch the Conservation Mode Off and let it fully charge.

My Yoga S1 has contradictory, intermittent power issues that I'm trying to chase down. Culprits are bad power bric/cord/plug or power socket on mother board or power board that feeds into power button/led on. One day it blacked out and wouldn't restart to hard drive or windows stage. I did get an error code which I can't remember 5100 or 5500 poss?, that seemed to indicate the power board or ribbons to that needed replacement or re-attachment. So fiddled with it and it did fire up in windows all ok. Then ran out of power and died again. power button wouldn't light up. plugging in power unit did light up led as getting charge.

So not recharging but I'm sure the battery is good. And logically, the power brick and plug must be feeding electricity into laptop to get it to recharge enough to start up.

Hi All,

I am trying to find the solution of the problem:

My laptop Equium A200 1V0 freezes up as soon as I plug in the AC power supply. I have already tried the new battery and new ac power adapter after reading some solutions from internet but so far no luck. It works fine without the ac plug'in but as soon as I join the power supply it freezes up and I have to force shutdown the machine which is not good.

I would be very grateful to you if anyone can please give me the solution in detail to the above mentioned problem and also let me know the cause of this trouble as well?

Thanks for reading this thread and for your effort.

A:Equium A200-1V0 - Freezes up after plug in the AC power supply?

Hey,

Do you use an original Toshiba AC/DC adapter? In my opinion the problem must be related to AC/DC adapter or mainboard itself?

Important is that you use Toshiba parts only so test it with an original Toshiba AC/DC adapter. If it doesn?t work it seems that the mainboard is malfunctioning. Such serious hardware issues can only be fixed from an authorized service provider so you should contact the guys and ask for help. ;)

Probably need new power supply as on/off switch on back of computer does nothing (won't turn computer on or off by that switch).

However, the ritual I seem forced to follow makes me wonder if that is my only problem--- Let me explain:

Hitting the switch on the front of the computer doesn't usually result in starting the computer-- but what does start it is to unplug the chord from the back of the computer and then plug it back in (unpluggin/pluggin in at surge protector doesn't usually have same results).

I leave machine running 24/7 and it works fine--- however, I am concerned that I want it repaired before it fails altogether.

Your help would be appreciated

A:Switch on Power Supply bad-- and need to plug cord in to start

Having to remove the cord to start is usually indicative of a PSU fault.
Though unplugging or turning off should have the same effect.

I am looking for a power supply that is adaptable to 12-volt and 110-volt source for my Dell Latitude D520. I am having a problem with identifying its tip (that plugs into the laptop). I know these things have names or numbers; but, I have no way of identifying mine.

Checking its dimensions with a digital caliper, the outside diameter of its barrel is appx 7.37mm or 0.29 inches. The inside diameter of its barrel (to the best of my ability to measure it with this tool) is 4.9 mm or 0.2 inches. The pin in the center is wire thin, possibly smaller than a mechanical pencil's fine lead.

The charger I'm looking at presently is this one; but, I might change my mind as I haven't satisfied myself this is the best I can do for the capacity and the money. I would really rather have one with a 120- to 140-watt rating; but, that's beside the point of my question right now.

I have included a scan of the charger's tip that fits.

I have an Alienware 17 R3 and recently updated the BIOS and the other day I noticed the ?annoying? blue ring on the charger switched off, to get it to come back on I need to disconnect from the laptop and switch off and on again. But several times since it will stay illuminated until I plug it in, the laptop hasn?t moved from my desk and the power pack has been under the desk so the only thing I think that could of damaged it would be this update.
It had a replacement motherboard a few months after purchase but now a few months out of warranty, is it only the power supply or worse?

A:Power supply blue light switches off when I plug it into the laptop.

If the LED on the DC plug doesn't stay on reliably, replace the adapter with a new OEM unit first.  If that doesn't solve the problem,  the next suspect is the system's DC jack -- replace this part
www.parts-people.com/index.php
If that doesn't solve the problem, the mainboard is bad -- Dell's warranty on replacement parts is 90 days.  If it's been less time than that, have the board replaced again.  If you had it replaced elsewhere, contact the repair shop to find out what warranty they offer on the repair they did.

I have 2 failed Z800 power supplies (1150 watt version). After some internet research I am led to believe this is a common problem and related to the PS capacitors.

Can anyone chime in and tell me if the new z840 1125 watt PS will work with my older z800? I have called HP support and spoken with the correct support people on this and they were not able to confirm if the Z840 PS will work (fit) on the z800.

Toshiba Satellite L305-5955, Ive taken apart and replaced power jack. Not directly soldered to motherboard. While still apart, and battery out/in, connected power supply and still absolutely no response. Power supply is NOT original, and slightly different specs, i.e original 19v..6.3A

Almost certainly the problem is that the current rating is wrong, if the laptop needs

Unfortunately it must be the right current rating, I know, I've been caught that way too!

I'm interested in the Toshiba G25 laptop but have heard that you can't use it on airplane seat power. It comes with a 120W AC power supply (15Vx8A), but I've been told that most airlines limit seat power to 75-90W max. Lind sells a 12V car adaptor for the G25, but specifically won't include an airline plug for this reason (which I can get independently, of course). I've read some interesting electrical discussions on this board. Can ya'll comment on the following or provide any general advice about power consumption?

1) Given that the voltage of the laptop and airline seat power pretty much match up (12-15V), if the amp draw on the laptop exceeds what the airline power supply can deliver, what will happen? Will it damage the laptop to feed it insufficient current? Will it shut down the laptop altogether? Merely dim the screen?

2) If I remove the laptop battery, which requires power to charge it, how much will that reduce the power need of the laptop? I'm not sure how to work the math, but the spec sheet states the battery supplies 4400mAh at 8A output. Does it require the same to charge it?

3) Most importantly, on my 15 hour transpacific flights, will the DVD player work with that ultrabrite screen at the low airline power supply?

Ive removed all parts and tried powering up and i cant get it to boot up. But the PC seems to work fine with the oldish 450 watt PSU which i find just unbelievable.

Can anyone help with this nightmare? Now on the Gigabyte site the CPU i have isnt listed as supported by this motherboard which is kinda worrying could this be the reason? If so how the old PSU boots up.

I unhooked my old psu, hooked up my new one and the PC turned on and I turned it back off from the power button on the case. I also hava a boot drive problem so I unplugged the sata cables from my SSD and wanted to try to turn on the PC with only my HDD. I did this with the PSU switched off and the power cord unplugged. When I tried turning the PC on again the PSU made a clicking noise and nothing turns on. The motherboard Led's are lit up so it is definitely getting power but when I go to turn the computer on it just makes a quick clicking noise and nothing turns on. Any help is appreciated, thanks!
 

A:Power Supply makes clicking noise when I press power button

You may just need to drain the power off from the power supply and try again. Unplug the power to the power supply, press and hold the power button for 30 seconds, then plug it back in and try to turn on the computer again. If that doesn't put the old power supply back in and see if the PC works, or was the old one dead? If the PC works with the old one and not the new one then you may have gotten a faulty power supply.

Hi, I just bought an HP pavilion e9300 a few week ago. And I am going to upgrade the power supply so that I can get a new graphic card--ATI 4870 which requires at least 500 watt power supply. My current computer is shipped with a 350 watt power supply. I will probably get a 650 watt considering the 70% effeciency of power supply.
However, when I talked to an HP technician, he insisted that I could go for a power supply with no more 450 watt. Because the system I just got has a motherboard which has a max power limit 450 watt. He said if I go beyond that, the motherboard will burn out.
So what shall I do? I really want to get ATI 4870 work well on my computer.
Thx very much.
 

A:Does power supply with higher power rating really burn motherboard?

The long answer is "No".
Just be sure of the dimensions of the power supply before you order a replacement, as HP uses some pretty strange sizes sometimes, and you want the new one to fit with room to spare.

The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.

Use a power supply calculator to get a accurate calculation of your power requirements.   Graphics card manufacturers have to figure a worst case scenario when giving power requirements.

It's been a while since I built a system from scratch and have a... errr... simple question

gfx: Sapphire HD3850 512MB Ultimate (passive)
http://www.sapphiretech.com/us/products/products_overview.php?gpid=225&grp=3

MB: MSI P35 Neo2 FIR
http://global.msi.com.tw/index.php?func=proddesc&prod_no=1261&maincat_no=1

PSU: Seasonic M12II 500W
http://www.seasonic.com/product/pc_retail.jsp

The motherboard has a power connector for the graphic card next to the slot.

Is there any reason I should connect the power for the card to the power connector on the board instead of directly to the power supply?
 

A:Graphic card power to power supply or connector on motherboard?

First time I have ever seen that feature. I like it. I'm thinking that is a neat/easy way to partially eliminate cable clutter from the PSU. Give it a shot, you can always revert to PSU cable if you wish.

Hello guys.  Can anyone help me understand the power supply on the HP Envy Phoenix 860-019?  The PCIE connector 6 pin connected to the GTX 960 has black and white wires.  Shouldn't there be yellow and black wires?  Yellow is usually 12 volt and black wires ground.  Is the 6 pin connected to my GTX 960  supplying a standard 75 watts of power or something else?  I want to install a GTX 1070 but the 6 pin wire colors are not the industry standard color scheme.  Also there is a 2 pin power connector with a white and black wire.  Usually a 6 pin and a 2 pin can be used together to connect into a 8 pin socket on a GTX 1070.  Will my connectors supply the needed power and connect properly because the color scheme on the wires make no sense. Thank you

I have just bought a Dell 19.5 V 90 W power supply adapter for a Dell from ebay. The PSU turned up this morning without a power cord. That's annoying enough but when I looked the connector needed is a type I have never seen before. The centre pin is slightly longer and wider than the other two so I assume that is the Earth pin. The centre pin is also offset between the other two. Again I suppose for connecting only 1 way. The two outer pins have a distance of just under 2 cms between them. Please can anyone tell me what type of connector this is. If I can get some info on it then I may be able to get one.

Thank you Terence

XPS 15 No Power to Unit. Tried Pulling Battery, CMBOS, Power Back,

CMBOS Voltage was 3.2V

Steps Taken
Tested Original Supply coming out at 19.7V ( rated 19.5)
Battery Voltage 11.1V to Logic Board
Power Button Tested fine for continuity when pressed
DC Jack Cable puts out the same power as what the power adapter supplies ( Was this supposed to step down the voltage?) I do know the E65XX series had less pins but put out 19v on some wires and 12v on the others) So I was thinking maybe the DC Adapter wasnt putting out the correct power?)
Ram was seated properly and tested for function.
It does not show any signs of power in terms of lights on the board and will not turn on.
Take tried to run it without battery. without battery and ram for lights, without one ram in each slot, with and without cmbos. have already tried taking out all electricity to board and taking out the remaining electricity in hopes to boot. Still no sign of life.

I need to get more info about the board to test the rest of the board.

Yea...so we finally got my girlfriends new PC up and running. The problem im having...or more of a concern really. Is when you flip off the power supply, and then flip it back on, the PC gets a short burst of power. IE the lights and fans all come on for a second or two. Then you can press the power button and turn it back on.

Any ideas guys?

Hello to the HP community. I must warn you all, this is a long thread and is potentially confusing, so only read this if you're interested in giving feedback. I am here today to not ask a question, but to share with you my confusion on your Pavilion desktop PCs. I've looked at the technical specifications for many of the Pavilion desktops, including my own, and I simply can't understand one thing; where do you get your PSU power ratings from? I currently have a Pavilion 500-319na: http://support.hp.com/us-en/document/c04343438.It's a good computer, powerful in most areas although the GPU isn't, so I'm looking to upgrade it. The first thing I check before I upgrade parts, and hopefully others do too, is the PSU's power rating. And this is where my problem lies. Firstly, your website states that for my PC, and others, it's an external power adapter. It simply isn't, as it's inside of the PC. I've seen in many discussions that this has confused people, including myself. And secondly, your website states that for many of the Pavilion PCs, including mine, the PSU is rated at 180W. Let me tell you why I believe is wrong: The PSU that comes with my PC, and presumably other Pavilions too, has four power outputs: 3.3V (12A) and 5.08V (10A) outputs, 'limited' at 70W. Then there are 12Va (7A) and 12Vb (10A) outputs. These apparently produce 180W. First of all, the 3.3V and 5.08V outputs can't be limited to 70W, in theory. This is because, using the equation...

Hi forum and pc gurus,

My problem is specified down to my PSU, at least I think so. (550W Logisys PSU - maybe the quality has something to do with it, I paid $19 for it from NEW EGG). I have A Gigabyte GA-965P-DS3 Motherboard, a Intel Core 2 DUO Conroe 2.13GHz processor with heatsink and Fan, Sapphire ATI X1950 Pro, 2 GIGS of WINTEC DDR2 PC 6400 (800) RAM, 1 SATA Maxtor 320 GIG HD, 1 2.5 inch SATA 160Gig HD, and two DVD Burner Optical Drives (both IDE).

I have it hooked up like this, two Optical Drives connected to 1 IDE connector/cable which is hooked into the IDE input on the motherboard, both are set to slave. Two CD outs (connected one to each Optical Drives) to one CD input on the motherboard. Both HD's are connected to SATA inputs on the motherboard, one is set for master, one is set for slave (I heard that it did not matter but wanted to state that anyway), then my ATI RADEON X1950 is hooked directly into my only PCI Xpress 16 slot. The power connectors are then all hooked into their respective inputs on the drives and Video Card. ANd last but not least, all the Power button and LED connectors are hooked into their input on the motherboard, wich I set up exactly as the motherboard diagrams and directions directed. I turned the switch on the PSU to on and I only got a faint mouse like squeek, then nothing, not even the fan. So I figured it was DOA, so I had newegg send me another. I got it today, installed it, hooked all the power connectors to the hardware, th... Read more

I shut down my Pavilion Elite for 1 week while away and now it will not turn on. The power supply light is on, I replaced the CMOS battery and the power switch is ok.

A:Pavilion elite power supply light on, won't power up

As you did not mention any message or display on the screen, I would use this tutorial for a step by step diagnostic.  It also helps to remove the side panel, and visually watch the CPU and rear case fan movement(s).  As you press the power button, pay attention to the fans. Also does the Power Supply LED stay ON? Or did it go OUT when you pressed the power button?

Several months ago I upgraded most of my PC.
ASRock Z370 Gaming K6
i7 8700k Coffee Lake
Team T-Force Vulcan DDR4 2800 (16 gigs)
EVGA Geforce GTX 970
2tb SATA hard drive

This was all running on a Corsair 500 watt power supply. Now a couple days ago I decided it was finally time to upgrade, so I bought another 16 gigs of the same RAM listed above and a Seasonic Focus+ 750 Gold power supply. (I think) everything is hooked up the way it should be, only now it's sounding like my hard drive doesn't want to turn on. It'll make a whir like it's trying but then it just makes a sound like it can't turn on. I'm assuming this is the problem because my motherboard can't detect the hard drive, and it's still plugged in the same spot I had it originally when it was working. I believe it was slot SATA3_0_1.
Faulty hard drive? Or hopefully I'm doing something wrong so I don't have to screw with returning it.
Any ideas would be warmly welcomed!

I have terrible luck with random bsod's and power supplies pooping on me, I want to pick one this time that will last me. Also, I have my power running through a Monster Power HT700, I live in a new apartment so the wiring should be ok, I've dusted out all of the components inside the case, double checked my connections, all that jazz. I've got a cooler over my memory, I am still using my stock cpu cooler, but thats changing soon (I get crashes @ idle too) Any help I could recieve I would appreciate, thanks

A:Hardware Power Consumption-Picking a new Power Supply

You have pretty much the same problem as me (getting BSOD's randomly). For me it's bulging capacitors on motherboard. You should take a closer look for capacitors on your motherboard. Dead capacitors look something like that:

Hi,
I'm currently a computing student so I rely on my computer a lot for my studies and was hoping I could get some quick advice/troubleshooting on here. So here goes :

I've had a problem with my computer recently, it's been working fine for a year or so with no problems, and then one day i tried switching it on and nothing happened. I tried once more and then the power short circuited (I then had to turn the power back on from the mains switch).

The strange thing is, my housemate had exactly the same problem, and after searching for the answer , he was told it was due to a static buildup and the solution was to take out components (graphics card, RAM) e.t.c and put them back in.

I tried this and no luck , I was thinking due to the short circuit, there may be a problem with a fuse in the power supply? other then that I'm completely stumped and would appreciate any help given.

Many Thanks for all help received
 

A:Computer won't power up (poss. power supply)

Does it happen with any other appliances? as in does using the toaster while using the kettle While your mate is in the Electric shower, telly on, or ironing?

Possibly a static build up, it is possible, Wher are you situated??
What voltage are you on?

What is the make and model of your comp? is it the same as your friends?

is your machine custom built or is it a brand?
Answer a few of them and we will try to narrow it down 4 you..

Mean while if you could get your hands on a spare PSU that would be handy. And remember when dealing with PSU's alway leave them to sischarge for at least 24hrs,
the 3 D'S, Disconect, discharge, dismantle.
