PSU down!

[martin-w 3,235]

Haven't tested yet. But looks like me EVGA PSU is kaput.

Have been getting freezes while idling for a while, reboots etc. Now no response at all from button on case or start button on board.

Start button on board is illuminated though. So I'm thinking it's generating enough juice to do that but nothing more.

Anybody else had PSU failure but still LED on board illuminated?

That might not be the PSU. Best way to debug is to disconnect everything from the motherboard except CPU, RAM and GPU and retry. If that still doesn't work, disconnect the GPU and retry. If it fails to turn on, try with a new PSU. If it doesn't work, you probably have the motherboard fried.

 I know what to do. Not my first time. 🙂

As I mentioned, haven't tested anything yet. Thats tomorrow.

Random lock ups and reboots are two of the symptoms of PSU failure. We will see tomorrow hopefully. 

That's the trouble with PC's though the same symptoms can be from multiple causes.

Simple enough for me to hook up my PSU tester before any component removal, or connect my spare PSU.

It's definitely possible to have some sections of the PSU working but not others.

Assuming you've done the obvious, like checking for loose connections, I'd probably start by going ugly early and swapping the PSU out--it that fixes it, you know where your problem is.  If not (ick) then more involved troubleshooting will be necessary.  But I agree that the odds are pretty good that it's the PSU.

I'm going to get stuck in tomorrow Bob. 

I don't need to remove the PSU, I can test it in situ with my tester. And/or conect my spare PSU without physically removing the suspect guy from the case.

Couldn't find ny PSU tester to check each rail, but it fired up by shorting the pins. So looks like PSU is fine. I'll order a new tester to be sure.

Spare graphics card generated same issue, so looks like 3090 is okay.

Looks like I'm heading toward motherboard failure. Will strip down to bare minimum tomorrow.

I need to test ram of course.

Yes, I watched that yesterday. No relevance to my issue.

I wonder how some pick a manufacturer for the PSU. When AIB partners don`t make GPU`s they make graphics cards and AMD and Nvidia supply them with the GPU, With PSU`s Seasonic Factory supply AIB partner with internal components, And Seasonic tend to be at higher end on prices.

I'm not with it today. Not quite sure what you mean.

Companies like Superflower, Seasonic etc, don't just supply components, they actually manufacture the PSU with the tweaks people like Corsair and EVGA request. For example Seasonic make Corsair PSU's and Corsair are just a reseller.

Who do you mean by "some"? Consumers or AIB?

Motherboard and PSU are fine.

It turned out to be a faulty stick of Trident Z DDR5.

Makes sense considering it refused to run at XMP settings. I put it down to the DDR5 XMP issues many were having. In hindsight, probably wasn't.
