Think I may have fried my PSU...not sure

post #1 of 5
Thread Starter 
I always told myself I need to get a UPS to protect my rig but kept putting it off and off and until finally I think I may have lost my chance...

We had a terrific power outtage just a couple days ago, and I don't think my crappy old surge protector did anything. The only problem I have now is occasionally the computer will just turn off. Im not talking shutting down on its own, but blatantly blacking out. It will not turn on for the next 30 seconds minimum (almost like it's charging up everything). But sometimes I have no issues at all. For instance I was folding for a straight 10 hours yesterday just fine. But this morning for a quick check and get some CAD files off before class, it made it half way through boot then shut off. After little recharge, it turned on just fine. Think it might be a faulty PSU, but am uncertain. Would a RMA remedy the situation?
Also I didn't smell anything burnt when the power outage happened, just left everything off and went to bed. I'm going to look into it further and crack the case when I get home from my classes, but looking for some pointers on what to look for.

Also, what UPS would everyone recommend? (As I don't think it's too late to get one. Cut my losses and get one now.)

I was thinking something like this: http://www.newegg.com/Product/Produc...82E16842102070

Power just cutting off doesn't hurt psu's that much. What will get them is a surge or brown out, that can be pretty hard on electronics in general. That is a pretty nice psu, so definitely RMA it if it is the culprit.

Don't open it up if you want to RMA it, opening it will void the warranty. Corsair are good with RMA's I'm pretty sure, they are one of the most respected sellers and provide good products.

That UPS you linked is decent, I have that model and have had it for around 2-3 yrs still works fine. I would suggest that or an APC branded one, as they are known for quality albeit a bit more expensive and I have had no issues with my Cyberpower yet. With a UPS around 800w capacity you should be able to have your rig+monitor run for around 8-12minutes idle. But really they are just handy to keep your system on long enough to properly shut down, and to keep your use from being disrupted. Shop around though once you pick out a UPS, newegg doesn't always have the best prices. I think I got mine from provantage back then, was somewhat cheaper..

Thanks Faster +rep

Yea I wasn't planning on opening the PSU, just kinda checking around with a flashlight inside trying to see if anything looked charred in any way. Don't like having my computer down so don't want to RMA if I don't have to.

I think part of the problem I might be having is from my old power strip and maybe a faulty wall outlet. Maybe a UPS will help me detect that. I'll whip out the trusty ol' DMM and see if it fluctuates at all.

The problem is almost never with the power cutting off, it's with what happens when the power comes back, or while it's off. If a tree just cuts a powerline, the power is off, no problem. The danger comes from when things get reconnected, or the power starts pulsing and spiking on and off. That's the time that out of spec spikes hit your PSU, now the TX should cope with a decent spike pretty well, but your power strip and any other accessories may not do so well.
Surge protection strips aren't there for your PSU in the main, that will cope fine, it's there to stop surges shooting through poorly shielded speaker setups and monitors into your rig that way.
I suggest that you unplug the PSU from the AC outlet for five minutes, just to totally reset all the trip circuits inside it, and then run some diagnostics over your rig, furmark, memtest and IBT, just to be sure all is OK.
Not quite sure what else to try after that, other than to go through all the parts and check them individually. Having a friend with a similar spec machine who is willing to let you spend all day moving hard drives and GPUs around is a god-send there.

Thanks for the tips will do anyways but I think I found the problem...

Was showing it off a few days before that Gotta love the smirks you get from a nice rig and think a wire came loose. Then after the power outage i bumped the computer in the process of reaching behind to turn everything off and unplug it all. I think that was the final straw and when I looked at it just the other day...the 24 pin connector went *click* when I pushed it in checking everything...

Hoping it was really that simple and no permanent damage from the outage. I feel like a tard, but lesson learned to always start with the basics before thinking of what else could be wrong!

Again thanks for all the helpful knowledgeable advice!
