OK to use 230V switch on power supply?

Q: OK to use 230V switch on power supply?

I'm wiring my new place right now and will have a dedicated circuit for the computer. Is there any reason why I can't run a 230V circuit for the power supply since it (Antec SmartPower 2.0 350W) can be switched to 230V? Nevermind the plug configuration....easy fix.
Just an FYI for folks on the computer all the time: Your watthour meter is measuring the higher of the current draw on L1 and L2. If you're plugged into 110V, you're still paying for 220V. Run anything off of 220V and you cut your power bill in half. A good reason to never buy a 110V window A/C unit!

A: OK to use 230V switch on power supply?

Definition:
"In electrical terms, one watt is the power produced by a current of one ampere flowing through an electric potential of one volt. "



what? We run at 120V here. Are talking about running your computer off the same line as your washer and dryer? Dryers run at 220V @60Hz which is actually just two separate 110V lines, if one of the 110V lines is off the dryer will spin but not heat. That switch on the back of the PSU is designed for other countries running higher voltage at 50Hz. You are asking for trouble if you try to wire it to a dryer outlet. Technically it may work but will likely reduce the life of the unit.

Amps are still amps regardless of the voltage, watt/voltage = amp. A PSU at 230V vs 110V will still draw the same current. You would actually be using more watts on a 230V outlet. Amp * voltage = watts.

Example: lets say a device is drawing 10A -> [email protected] , [email protected]


How do you figure that your powerbill will be any cheaper plugging into a higher voltage?

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.

I recently thought that the motherboard in my machine had died. No power on light on the front panel, motherboard power light WAS on, nothing showing on monitor except a flashing ready light, hard drive not powering up or spinning, no activity of any kind.
Replaced motherboard with an exact make and model #.When attempting to boot the machine now, the power light on the PSU doesn't light.Whan the power switch is pressed, the PSU comes on for 1-2 seconds then goes off.Does the same thing when pins 14 and 15 are jumped over.
Tried a known good PSU from another machine. It passed the pin jumper test.
Once connected to the machine, it does the same on/off thing like the original.
Suggestions anyone? All welcome.
Also tried resetting the CMOS,just in case.

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.

PS a "chord" is a series of three or more musical notes...

Have a 5 y.o. local built white box tower that I'm happy with. Recently unplugged for ten days while on vacation. Came back and first had a hard time getting the back switch to power up, then had to use front switch reset button several times to get the entire unit to power up.

Since then when I power down or unplug, it's very unreliable about powering back up on either switch. I can tell that sometimes the power is getting through due to the light on my router and other times it's not. Even if it is getting through then the front switch may have to be reset several times to actually boot.

Also, after powering down at night via "shut down" on screen or using the front switch (Windows XP Home), then sometimes I can see the DVDRW trying to power up, or see the HD trying to power up - over and over and over.

the receipt describes the case only as ATX4252PCT and the PSU as 340W PS for P4 w/UL.

I've installed one PSU (PC power and cooling dell silencer 470) on a Dell and confident I can do this one. I've never replaced a front switch and don't know anything about this one other than it appears to be integrated with the case.

Need to blow the dust out of the unit but otherwise don't know what else to do. 'fraid to shut down too many more times.

So, do you think it's the PSU or the front switch or both that have a problem? Could I have killed some 5 y.o. backup battery by unplugging for 10 days? Is it a... Read more

A:Power supply or front push button switch?

Replace the power supply with one 350 Watts or greater... of quality, as well as the CMOS battery.
The replacement CMOS battery is only $3.50 at Wal-Mart, and it has been enough time for that to be bad.
Switches rarely to very rarely go bad.
On a computer with that many hours, it could also be the hard drive, but the symptoms are more likely the power supply.

Here is my story,

First off all I am building computers for a couple of years now and I know what I am doing, but This problem arrived the other day after changing my case. 2 Days Ago I bought A new Case and a new Burner for my Computer.
I unintalled everything and installed it in my new Case. I plugged everything back up and was on my computer again without any problems.

I used the reset button, but it was behaving oddly, the computer was still running but the monitor turned itself off. So I though that maybe I had installed the reset Switch the wrong way. I couldn't stop it anymore so I closed it with the Power Supply Switch. So I opened my case to see if everything was ok, Everything was as it was supposed to be. I played with the connectors a little bit to make sure they were well connected. I tried running the computers again, but it wouldn't start. It didin't make a noise, no fan running, no BIOS, nothing. I was very afraid to have killed my Power Supply or MOBO by closing it the wrong way.

I though that maybe it was just the power button of my new case that was the problem, so I connected the Reset Switch connector in the Power Switch. I tried turning it on and it worked. I was very releaved that it was just that problem. So I left it opened all night and went to work, I also accesed my computer remotely from work almost all day.

Hello and welcome to Techspot.

If after trying your other psu it`s still dead, It`s got to be either the mobo or cpu.

I think for whatever reason, you`ve had a short circuit of some kind and it`s fried either the psu/mobo/cpu.

You`ve seem to have tried all the right things, so I can`t really suggest anything else.

Hello,
 
I've had this strange problem for a while. I tried googling but I ended up with no luck. This is how it started:
 
whenever I turned my computer on, the first thing I had to do was change my "power plan" (the one from battery icon thingy) to "power saver". If i left it at balanced, it crashed within 1 minute or less. If i switched to "power plan" it ran fine. Then I could play the game and in between the game if I alt+tab'ed and switched to "balanced power option" then everything would be fine. The computer would not crash.
 
Also if I left the computer idle (w/o doing anything; no game etc) then it would crash.
 
It's not the heat issue. There is no virus either.
 
anyway, the issue progressed with time. eventually it became like flipping a coin. even if i switched to "power saver" on startup, it would still crash often. usually it took like 5-6 tries before it "worked". then business as usual: play in power saver for a bit and switch to balanced in between the game.
 
recently, the computer doesn't even start. i would be lucky to get to login screen now. i can only run in safe mode.
 
 
please help.

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. Since I do not know how to do this capacitor replacement (yet). I thought I would buy a new PS. However, I do not want to buy a Z800 PS since it seems to me to be a defective design. 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.

It could be anything; 200W or 1000W. You need to look at the specs of the unit. There should be a label on the ps with the info.

BTW to find watts, you need to apply the basic formula VxA=W [volts times amps = watts]

This story is super long. So I go in to clean my comp and I have been noticing that my startup has been pretty slow lately. So I cleaned out everything and decided to switch my RAM to different slots. Once I did all this I turned on my comp and my monitor failed to respond. So I put my RAM on their original spots and this time it decided to respond but I also noticed that my heat/cooling fan fell off. I then tried to turn the computer on. But I switched the volt button to 230 while it was off and it responded but my comp instantly turned off. I then found out that I basically destroyed my PSU. I went to the store and got thermal paste and a new PSU and pasted down my fan and installed my new PSU. What I failed to check is to see is if the switch was on 115v or 230v. The switch was towards 230v showing 115v. Did I destroy my PSU again? Also my RAM isn't the problem because I tested it. So when I turned my computer on the same thing happened as the one I previously ruined. Would I need to buy another PSU?
If so on the voltage switch which voltage option is being selected? If the switch to towards 230v and showing 115v or is it the opposite? I know it sounds dumb but I'm that cautious now!

Oh and I also tested my Motherboard so that also isn't the problem.

Hi

It sounds good on paper and I am sure it would answer peoples question on whether to go hard wired or wireless
Any views or opinions?
http://www.netgear.co.uk/wallplugged_ethernet_bridge_xe102.php
 

A:Networking using 230V opinions please

Hello,

Based on your subject line, I suspect the only thing you might get out of that particular Netgear product would be some popping noises and possibly some smoke. It is listed as 110 VAC operation only. Any type of simple voltage conversion transformer would probably
block the the data signals.

The unit may have problems in US homes with 240/120 VAC power wiring. I suspect that it may not work too well, if at all, if each unit was plugged into a different 120 VAC phase.

It lists a 14 Mbps data rate. This is slighty faster than a 10 Mbps wired ethernet connection but only 1/7 the speed of most typical wired ethernet connections which are 100 Mbps.

It is slightly faster than an 11 Mbps 802.11b wireless connection but only about 1/4 the speed of a typical 802.11g wireless connection.

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?

Hi, so I have had a powering issue with my previous power supply which was the Corsair CX600W so i purchased a newer power supply - the EVGA SuperNova G2 550W. 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.

if I read the specifications right on your mobo... it implies that it has the 4 pin PCI-e input(power) but it also has the 8pin ATX power conector. (it may be simply removing a cap that is actually right next to the 4 pin connector, thus making it an 8 pin connector (thats how it was on my mobo)

Try using the 8pin power with your new PSU, see if that works.

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.

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 an enquiry relating to video cards. In order to do my job, I need to get a card with at least 512MB of VRAM, preferably 2GB. However, the ones I've found online use 300w What's the maximum watts that I can use with my Lenovo H520s? And what would happen if I used a 300w video card in it?

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.

I have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. 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.

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.

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
 

A:Bent power supply pin - Hard to plug in power cord

umm.. bend it back so it's closer to normal? That's all I can say about it. usually works for me.

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

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:

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?

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...

Last night my computer blue screened about 3 times then it just stopped turning on altogether. Wheni plug the power supply into the motherboard the neon fan turns on for a milisecond but that seems to be the only way that i can tell that there's power going to the motherboard.

I've tried 4 different power supplies, different processor, different BIOS batteries, different RAM, etc, but no matter how many times i try to turn it on it just wont turn on.

I do recall doing something innthe BIOS last night which seemed to start this dilemer. I went into power management and did something to the power switch option, then set everything back to default settings.

This is when things started to happen then my pc just wouldn't turn on at all.

It's a socket939 MSI CoreCell.

Could something i did in the BIOS really be causing this problem and is there a way to fix it?

Like i said there does seem to be power going to the motherboard but it simply wont turn on (i even tried different power switches just in [email protected]

Any help would be greatly appreciated. I just don't want to buy another 939 motherboard as most shops don't cell them any more and it means i'd have to buy a new processor too.
 

A:Computer wont turn on with power switch but there is power going through it?

If it is a BIOS setting, removing the CMOS battery for a few minutes should clear it. Since you've already changed the battery more than once, it would seem that is not the problem. Considering what you already tried, it might be the motherboard itself or possibly the graphics card but my money is on the motherboard. Just to be sure do you have another graphics card to test with?
