PSU dead or start button fails

[oguzbir]

Hey Rappet.

I had a similar problem with psu.
With a 860w corsair psu. Stopped working, Board was Asus rampage IV
working with 2 gpus 5- disk drives.

It turned out to be either things
I didn't connect the pcie power to the board giving extra power when needed.
I kinda sorted out my problem but then it reoccured.
Clicking power button on my cosmos II case sometime worked sometimes not.
Some times I reset bios. And powering the button worked.
I even changed the mainboard battery where I heard some problems about it.
The problem continued.

I was pissed with this and purchased Cosair 1500axi psu.
All problems went away.
But I did check the PSU with other PC. I worked flawlessly as before.
Maybe your psu cant handle it. after some changes you forgot doing/adding to the system.
An overclock maybe?

Cheers,

You could recheck the connections to the mother board.

Connectors are the bane of all known existence. Its always disturbing when a problem appears and goes away without explanation. In fact I'd take the time to locate a replacement switch in case it happens again. Power supply failures are annoying, but easy to replace (as long as there's no fire.)
