Random power loss

I purchased a Corsair GS600w about 2-3 months ago.
Link for reference

Over the last few months I've been getting random drop outs. The power of the PC will just shut off immediately with zero indication that it was failing. As I'm sure you all could imagine, this is very very inconvenient, especially if I'm rendering a video/capturing footage.

Another weird thing, that I've only experienced with this current build of mine that when I start it up (or after these power failures) the PC will restart twice. It boots up, hits the first boot screen, and shuts off. 5 seconds later, it boots up just fine without me touching anything. It does this every time.

I have no idea what could be the reason - but I assume power troubles = PSU?

I love Corsair, I've never had any problems with their products. Which is why I'm hesitant to say that it may be my PSU.

It's hooked into a UPS (Fairly big one) as well, so it's not like it's the plug in my wall.

CPU is overclocked but never overheats, video card is the same. Both have higher end aftermarket coolers on them so they don't even get near hot.

The power failures are completely random. I'll be fine for 2 weeks and BAM, it happens. Or it'll happen twice within 4 hours like it did tonight. I can't even figure out if I'm doing something my PC hates, what I'm doing on the computer at the time seems to have no effect to it. It's happened with me playing games, watching videos, or just listening to music. Never seen it do it while the system was idling though.

Anyways - full PC specs are in my signature. I don't have another PSU to swap to see if that'll help.

Thanks!
 
Contrary to popular belief, Corsair PSUs aren't really made by God and baby Jesus isn't being sodomized every time a Corsair unit fails ;)

On the subject, you need to check the voltage drop on the 12v rail, for that you will need a multimeter.. software measurements are generally pointless but it wouldn't hurt to d/l AIDA64 and see what values you get.. come back with the results, preferably the multimeter ones and we'll pick it up from there :)

Even if it is your power supply, its got a warrantly and Corsair service is 1st class. Don't panic, follow profumo's advice and let us know.

My corsair went south on me, it got swapped straight out with no fuss. Would i buy corsair again? Most definately

Heat doesn't necessarily equal instability... and conversely lack of heat doesn't mean rock solid stability. Run everything at stock and see if you still have problems.

If not, then you know you probably need to start applying extra voltage to stabilize your overclocks.

Alright well I do have a multimeter, how would I go about testing it?

Hey, sorry for the late reply.. Your PSU has a single 12v rail so you could check the voltage drop on that rail on an unused Molex connector, but if you're comfortable enough check directly @ the plugged-in 20+4pin & PCIe connector/s, there are plenty of tutorials for this on Youtube and other places, just be sure you get the right wires.. First check them at idle, then at a typical load(gaming/multitasking/etc) and finally running Prime or Lynx and Furmark simultaneously ;)
