Power Supply Shortage

[squilly827]

I don't really know what's going on. I have a Corsair TX750 and a Gigabyte Z77 to start. I turned my computer on as I normally do and, during the boot, my computer randomly shuts off. It didn't turn back on which tells me the PSU is dead or it's touching something it wasn't touching before. I tried re-connecting most of the cables without luck, also switching the PSU switch on and off multiple times. No luck.
After 3 days of the issue, I created an RMA with Corsair, about to send it out. I try switching it on again, with a flicker of the power button on the motherboard which wasn't there before. It was barely on but may be a glimmer of hope. Is the PSU dead? Or not grounded? Or should I just send it in for RMA replacement?

The PSU does seem to be acting up and you want something stable in there, I say RMA that puppy!

Could it be the motherboard? Or most likely the PSU?

Although it could be the motherboard, I'm more focused on the PSU as being the culprit here

Tried flipping the switch again. Same occurrence as before every time, the power button on the motherboard flickers for a second and nothing happens. If the PSU was truly dead, why is that happening?

PSU's don't always die in the same manner, capacitors age and can no longer hold a charge, components overheat and start producing "wonky" voltages, sometimes (the really cheap ones) they burst into flames. Basically, some die fast and some just like the dramatic effect of dying slowly - actually the slow diers are the nasty ones when it comes to troubleshooting since they can cause all kinds of other issues not usually associated with power

One other suggestion here - try resetting your CMOS but honestly, I'm kind of 'reaching' with that suggestion - but it's easy and (best of all) free
