Is switching the psu on and off at the back of the psu fine practice and won't damage anything? It's a bloody pain...

EDIT:

Ok so far so good. I've cleared the CMOS and loaded setup defaults in the BIOS. Re-enabled AHCI mode for the SSD and re-enabled my CPU-OC. The PC successfully boots from pressing the button on the case. But I have to press it really hard down sometimes..so heres hoping its fixed. It may be that something blew the fuse in our house a while back and that it messed with my power s/w ?

If you're having to press extra hard, then perhaps the case's switch is wearing out.

It shouldn't matter how hard you press the front panel switch because it's not a high current switch but just one that uses a low current signal -- very low current, probably .001 amp at most.

The issue here is probably in the +5Vstandby circuit, which starts the rest of the PSU, and the fact that turning off the rear switch makes the PSU work again could mean a cracked solder joint cools off and restores conduction by moving very slightly.

Sounds to me like a problem with the M/B latching circuit. This is what keeps the circuit closed after you release the button on the front of the PC. When you push the button you are bypassing this on the motherboard and then when the mother see's the box it closes a switch on the M/B until it is told to open this is what keeps the power supply working...

another thought I would check the low power state in the bios and turn it off. because this is what it sounds like to me. you are having to remove all power let the mother board reset then it comes on.

I'll look into it. But right now I've pressed the case button, and it starts up every time so I think the clear cmos fixed it, I think when our fuse box blew the other day it messed with my mobo's power somhow, seems great now smile.gif. The PC has successfully booted as normal, and it appears now I only need to press the button as usual. If anything crops up later, I'll be sure to post here.

Thanks everyone

Oh good. Its not firing up again! Having to cycle the power switch on the unit to boot up. I'm going spare now...

I remember when it did fire up I hear a sound like the flick of a switch then it comes on...strange?

Ive asked the shop if i can rma it. Best thing to do? I swear i get all the luck with power supplies...

I think that this click sound is normal and it's just the way these particular units are designed.

If you can RMA it, see if you can just return it so that you can buy a different one, like perhaps a good unit that has a smaller capacity. I mean, the only good reason for having a high-end 1000W PSU is if you want to have like 3 or 4 high-end video cards.

Yeah I've messaged the shop. Just waiting on a reply. I've put my old PSU in. Old PSU boots every time.
