PC dead probably after a lightning storm.

Looking at the specs for your rig John I see that it is a corsair 650. With what you have you can get away with a cheap 30 dollar 300 watt psu for now. It will run and game ok. I have an old nvidia 680i system with an e8400 using an 8800gtx gpu and I stuck a 300 watt in it after it's 850 watt psu died and it ran fine. It has the 850 back in it now as I have repaired it but it had the 300 in it for over a month before I got around to fixing it.
Oh it was doing exactly what you described, psu would come on for a sec and the mb lights were on but no boot. I had to replace 6 caps in it and after 8 months it is still going strong.
So if you have a lesser psu kicking around or you can get one cheap you should be ok until you can afford better or fix the old one..

I already submitted my case to Corsair, to make an RMA. They sent me the instructions to send them my PSU to its headquarters in California (I live far away from the US :( ). I forgot to say, but I am not really sure if the thunderstorm was the cause of my problem. I have two generic PSU, one that I bought 4 or 5 years ago (used one year), and the one that came with my case, which is new, never used. I dont think they can handle the 12V wattage that my GPU needs, but I will see on those PSU their 12V values to be sure.
Regarding myself repairing the psu, I dont think its a good idea for me, I dont want to play with my psu, I will use the RMA because it is still under the 5 year manufacturer guarantee.

I know you said it probably is the PSU.

But have you tried a completely different outlet? Reason being is the Printer does the same thing.

I didn't tried that one lol, but I don't have any other outlet near my PC D:

It's not a big thing to try. Just unplug everything, and take the PSU cable with ya and the case. Plug it in, hit the power button and see if it stays on. :)

Tomorrow I'll try the old PSU I have. It has an 6pin pci express connector thank to god!. But can I test the PSU if it works, without connecting to the system first, with the paperclip way??.
Here are the details of my generic PSU that I found (it doesn't says clearly the wattage on the 12v rail):

Output: 650 MAX
Red +5 V 50A
Yellow +12 V1 19A
Yel/Blk +12 V2 19A
Blue -12 V 1.0A
Orange +3.3 V 32A
Purple +5 VSB 2.0A
Gray P.G.
Black GND
Green PS-ON
(+5V & +3.3V TOTAL OUTPUT 460W)

These are the specs of my old PSU. One more thing, if the PSU when plugging it to my system, if it can't take the load, will it damage my PC?.

P.D.: Its a pain writing from my smartphone on the forum ;)

That "generic" PSU will power your system no problem. Should be fine to run on it until your get your RMA back as well.

The first thing I try when a PC won't power up is another PSU. Anything 300w+ (generic or not) will at least allow a PC to POST.

Another question for you guys, the old psu has only a 4pin atx12v connector, but my motherboard has an 8pin atx12v. Can I use it??. I remember using this psu with this motherboard before my Corsair psu, that's why I don't know how it worked. The connectors on the Corsair psu are two 4pin connector, that fit at the same time at the board.

[russ18uk]

It should work, the 4pin will only fit on on side. OCing may be limited.

[Masterchief John152]

Yea, you can use a 4 on an 8. Most boards are set up to allow that. Check the manual to see what side to use, not sure if it matters though. My p6t mb tells you in the book what side to use, in my case it is, with the lip for the cable lock facing down, on the left side. If you don't have the book let me know what MB you have and I will find the info for if if need be.

On my board manual, on the inferior right pin of the 8 pins, says pin 1, I suppose there goes the 4 pin connector. The support for the connector its also just in the right side.
