Lost all Power - New Build

Recommended Posts

Hello,

 

Moderators, if this topic isin correct for this forum, feel free to move.

 

I was 2 hours into a flight and my new build suddenly lost all power. I cannot turn it on, nothing happens when I use the power switch attached to the PSU.

 

I believe something happen with the wall outlet, because it is not working now. Just checked the circuit breaker and it was tripped. I had 2 surge protectors plugged into the wall outlet.

Surge Protector #1 - New build, monitors, speakers, etc

Surge Protector#2 - Old computer, monitor

 

 

 

I plugged everything into another wall outlet, the old computer works fine but my new build has no power.

 

Specs (not OC):

PSU: Corsair HX750

MB: ASUS P8Z77-V PRO LGA

EVGA GTX680

i7 3770K

RAM: Corsair Vengeance 8GB (2 x 4GB)

 

I went to Corsair's site and they have a troubleshooting section. I tested the PSU by uplugging everything from the computer but using a paperclip (PSU plugged into the wall) and the fan didn't start. I find it strange that a tripped circuit would cause the PSU to go out.

 

I'm so bummed after getting everything set up this past month and having this happen. I would really appreciate any advice and steps to follow for a non tech person.

 

Thanks!, CK

Just to clarify - you plugged the PSU into the wall with nothing attached to it? All pc connctions were disconnected from it? It wouldn't start, no fan, etc - its a digital start circuit or did you short that with a paper clip to get it going - not sure I understand that part.

Sorry I wasn't clear. I did plug it in the wall with nothing attached. I short circuited with the paper clip and the fan didn't start. That was recommended from the corsair tech support page.

 

Q: How can I test my power supply?

A: You can easily test a power supply for functionality with a simple paperclip. First, disconnect all the cables from your motherboard and other devices, but leave the power supply plugged into the wall. Next, bend the paperclip until you have a U shape. Find the 24-pin ATX connector and plug one part of the paperclip into the socket where the green wire ends, and the other end into the socket where a black wire ends. Make sure the power switch on the back of the PSU is on, (should be the I symbol) and the fan should spin up. If it doesn’t, your power supply may be bad.

My first post - perhaps it will help!

 

I upgraded my Dell PSU to an HX650, and similar to your situation, I was able to fly for about 90 minutes and then wasa greeted with the sounds and smell of a fried power supply.

 

The fan *never* came on, out of the box. I remember when I first powered it up thinking "that is the quietest power supply I have ever heard". No fan, that's why. Oddly enough, I came home from work and my son was on the computer, but after a while, down she went again.

 

Have Corsair RMA the unit. They can turn it around very quickly.

Thanks JKH,

 

I've already started the RMA process but wanted to check to see if there is anything else I should try. I didn't smell anything. I just find it odd that it would go out because of a tripped circuit, I had everything running for about 9 hours a couple of days ago.

Unless there is a reset button in the psu it sounds like from your testing that it does not work anymore. You could always put a meter across the the 2 terminals as above and see if there is any current/voltage, etc. I lost a psu recently in a "brown out" even though it was connected via a surge protection device but in this instance you could smell the cooked electronics. Is there any warranty/guarantee with your surge protector - you might be able to claim for your psu via them. Can you get it checked by a competenet electrician/electronics, does another psu work and so on. Return to Corsair as faulty?

Thanks everyone for the helpful responses. I'm definitely not the best with "electricity". I do have another PSU on my other computer but it's 600w. I was a little nervous that might cause issues with the new build. Do you think it would be okay to use it to test the new build?

 

Hindsight...I shouldn't have loaded the wall socket with 2 surge protectors, 2 computers, 4 monitors, etc. Stupid mistake

 

No warranty with the surge protector (it's old). I was going to burrow a friends multimeter or voltmeter to check a few things, but I think I will send it back to Corsair and see what they say.

 

Thanks again and have a good weekend.

Take your GTX 680 out and use the onboard graphics with the 600w PSU.

This is very common when a PSU fails.

 

Same thing happened to me last year.

 

The failing PSU trips your circuit breakers. This is what's supposed to happen when an electrical component somewhere in your house fails. Even a blown light bulb can trip an MCB.

 

MCB's, and RCD's [as we call them in thre UK] are very sensitve these days.

 

Be warned, your surge protectors "may" now need to be replaced. Mine was dead after my incident. So do test them.

 

Overloading the socket shouldn't damage components, it will simply blow your consumer unit circuit breaker. That's what it's designed to do. In the UK, some of our outlets [triple outlets] have fuses that can blow.

Thanks for the explanation, which really helps my "ease of mind". I'm going to replace the surge protector. It's very old and they don't cost too much.

 

Cheers, Chris

No problem. :smile:

 

The day it happened to me, my PSU blew, a chair in the kitchen broke, and I ended up re-injuring my back trying to fix the chair... all on the same day.

 

Don't be put off Corsair PSU's, they are of exceptional quality. I always buy Corsair PSU's.

Thought I would provide a quick update.

 

Looks like it was a bad PSU. I've received my replacement from Corsair and everything is up and running.

 

Customer service at Corsair is outstanding. My old PSU arrived at Corsair on Monday. Replacement was sent Tuesday and the item arrived via 3 day UPS today. I was blown away how fast it shipped.

That all depends... on what else is on the circuit.

 

It could be you have three sockets in the room and all on the same circuit... there could be 'a gazillion' things plugged in... or e.g. maybe all bedroom sockets are on the same circuit.

 

Could be the socket you plugged into has relatively nothing else on it (not likely but...) then no problem... you see? It's not the socket that was overloaded rather the circuit - and my guess because the failing psu pulled more amps (plus with whatever else was on the circuit) than it should have if running normally, it tripped the breaker.

 

You can fairly easily find out if you were pushing the circuit too hard. 15amp breaker (typically) x 120v and roughly 80% of 1800 watts for a continuous load... (1400w or so).

 

Find out what the circuit is rated for... what is on the circuit (in watts)... add it up and make sure it is less than what the circuit is rated for. A computer (or whatever on the UPS or a powerstrip) will take a bit to determine actually watt usage. There are watt meters one can purchase, but a site like this http://www.extreme.outervision.com/PSUEngine should be sufficient for a ballpark figure.
