[SOLVED] PSU acting up on Cold Boot.

**Aus_Karlos** · 05-08-2008, 06:57 AM

On a very rare occasion my PSU will power off before the beeps of the motherboard. But then it will instantly turn back on. I know its the PSU and not the motherboard as all my fans that are connected directly to the PSU and they stop spinning.

I do have some Hardware OC'ed CPU, FSB (Motherboard) some voltages have been upped but PSU can handle it.. PSU on the left.

Can anyone help me..

check the psu with a multi meter even the best brands have failures
there was a similar occurance on the asus p35 chipsets which a bios update fixed

Found the problem. It is partially due to my PSU, Im running to much off of one Power Socket. The poor 2.5mm cable is carrying to much current, It spikes and causes my PSU to turn off. I think im pulling close to 10-16amp in my room.
So what im going to do is re-cable my room and use 4mm and add an extra breaker in the board just for my room... LOL
