Question Desktop just shut off and won't turn back on

[Steelbom]

Hi,

Last night my desktop just shut off. The UPS went into short circuit mode and shut off.
Tried plugging it just into a socket directly which also tripped the rcd again in the circuit board.

This is the system in the rig. Never had this happen before.
I have the THOR 1600W ROG PSU (for about 3-4 months)...

Dead PSU? If I unplug the PSU from the computer and try to turn it on just connected to an outlet, is that a good way to check if its just the PSU that is faulty as opposed to a component inside?

Cheers,
SB

You would need a jumper on the 24 pin to actually turn on the PSU if it is disconnected from everything. Another option is to get a PSU tester or see if a local shop can test it for you.

Thanks for your reply!

I tried connecting the 24 pin from the motherboard, but still nothing! I tried the power button on the computer and also the power button directly on the motherboard. Nothing is tripping but also nothing is turning on.

It's a public holiday today so all the stores are closed. Not sure how I can test it any further.

Try the Seasonic PSU in your sig if you still have it. I'm guessing that your hardware is fine and it's the Thor PSU.

Yep, I managed to find a tech that could come out. He tested it on a PSU he brought and everything posted... using the Seasonic now.
Out of curiosity, what would make a high end PSU just suddenly die like that? I guess it has to happen to some of them?

Likely just a failure of one or more of the components. When I built my son's PC last year I had a similar issue with a Corsair 650W unit. It worked fine for a few days then just crapped out (it had a slightly weird smell from the moment we opened the box, like a capacitor that has failed). I bought an EVGA from a local shop that we could use until it got replaced (was inside the 30 day return window). The EVGA now sits in the closet as a backup/test PSU.

Glad to see your problem was resolved. You could consider picking up a cheap PSU tester to keep on hand for the future. I tend to use one when I start building, just to make sure a new power supply will actually turn on (and it does give voltage readouts, but not sure how reliable those are without a true load). (And as an aside, it's also a safer way to test if a PSU will turn on compared with manually jumping it by connecting two of the pins on the 24-pin plug)

Right, I see. It was working nicely for about a month and then gone. No sound no smell. Super odd! Thanks again.
Fortunately, I did have my old PSU on hand. Definitely need to keep it as a backup!

Yes, that's a good idea, thanks! Never realized I needed one until now

Sounds like LOTS of people have been having issues with these PSUs.

Oof. Thanks for the link. I might see if I can get a refund.
