Unhappy Boot up issue: need to flick the PSU on/off to switch the PC On

Hi,

I have this problem with my PC where I have to flick the PSU on/off (sometimes a couple of times) in order for it to switch On. The power button seems to not to work for me.

This is my I second motherboard and all other parts are still same and I think the issue is not the motherboard. I don't want to wait to have another part get damage as I don't have that deep pocket.

I still have my old PSU which is Hec 550 W, not sure if it is a good idea to try this one if I will still see that issue.

Please advise.

CPU: I7-960
Mobo: ASUS X58 Sabertooth (before I have ASUS P6T that gave up after 2 years)
Ram: 3 Ch G. Skill
GPU: Sapphire 6970
PSU: Seasonic 850W
2 HDD + 1 DVD Rom (R/W)

If the HEC is still working, then give it a shot. 550W is all you need for any single-GPU rig

First I lessen the load by not using 1 of my HDDs and the DVD ROM. But still it didn't boot properly, that is I still have to the "on/off/on on the PSU's switch".

Then I gave a shot and swapped my old HEC 550W and it booted up properly using the casing power button. Just to make sure, I did this twice.

"I'm not sure", but I can't stop thinking that this could also be the reason why my old Asus P6T gave up.

Next thing for me is to contact the Seasonic's support guys and hope for a replacement.

Added info: lately I'm seeing my PC trips off at random.

If it's under warranty, then you should have no problems getting a replacement from Seasonic. We'll probably never know if it was the cause of your old board failing. Knowing ASUS, though, it probably wasn't.
