[SOLVED] Is my PSU faulty?

[Darkshadow834]

Hi all,

I have a bit of an odd issue I can't work out, when I turn my computers power on from the power supply (as in the whole pc has no power and than I switch it on from the power supply) the PC power Cycles a few times about 3 seconds after the power has been turned on.

Everything works fine with no issues and it boots etc. But, this also happens when I shut down, so the PC has now shut down fans have stopped and it's completely shut down, after about 3 seconds again, the PC will power cycle a few times before returning to normal and the MB LEDs are back to normal etc.

Being that everything still works fine I'm not too fussed just yet, I am very concerned however as to 1. Why is this happening and 2. I'm afraid to many power Cycles will short out something.

This issue started out of nowhere around a month or two ago, one morning I just woke up and it was doing this, I have tried clearing cmos through traditional means of removing the battery etc and using the clear cmos button on the motherboard with no luck, I know the basics of hardware issues and usually can trouble shoot stuff my self but on this one I am lost. I've also tried different power cable with no luck.

Edit - wanted to add that that when this power cycle finishes I do hear what sound like a zap sort of a click from the PSU this has me thinking that it's faulty and I should replace it, but would like a few opinions in case this isn't the issue.

PC specs are below:

PSU - Corsair RM1000W 80 gold
GPU - Rtx 2080Ti
CPU - 9900KS edition
MB - Asus ROG maximus xi extreme
RAM - Corsair vengeance LPX DDR4 16gb @3200MHz

Power cycles are usually a motherboard thing IIRC, so I don't think it has to do with the PSU. Are you able to test the rig with another PSU to make sure whether or not it's the PSU?

unfortunately i don't have a spare PSU handy to do this, the motherboard was my first thought and why i even bothered to try and clear the CMOS, incase somehow somthing there was erroring but no luck there.
Being that everything works fine and this simply happens after shutting down and when turning on from the power supply, is this somthing i should still worry about and look at maybe getting another MB ? but than again for a ($800 in my local currency) Motherboard, that has worked with no issues for the just over a year that i've had it, surely this isn't faulting

Yes, your MB is somewhat too overkill for anyone, but it isn't immune to issues. If it plays fine and there's no instability issues then I'd say you don't have to worry too much. Consider it as a small MB bug.
