Question PSU Recommendation and Question

[kaidorpheus]

My PSU is broken because of a leak opened in my ceiling during a heavy storm and dripped a bit of water directly into my PSU. I was asleep at that time and was not able to unplugged everything. I checked every parts and it seems that other parts are dry. I cant troubleshoot it because I don't have spare parts neither someone that have pc. Now i am planning to buy a power supply tomorrow that will last for couple of years and i am interested in atx 3.0/3.1 ready PSU for future GPU upgrade. It was unfortunate and sad because I've been using my PSU since 2018.

What are the chances of my whole system getting fry? Can i use PSU with atx 3.0/3.1 with my current GPU? What PSU should you recommend?

Specs:
CPU: AMD Ryzen 5700x
Mobo: Asus rog strix b550-a
GPU: Asus rog strix rx vega 64
PSU: EVGA SuperNOVA 750 G+

Only way to know would be to test.

A cheap option when it comes back in stock.

If you are in a different country/currency, please indicate so. Available PSUs are quite variable by location.

can i still use the psu with atx 3.0/3.1 with old gpu ports?

Yes. They still have plenty of 8-pin PCIe connectors.

yikes i would assume more than just the psu got fried.

If the PSU detected a short/overcurrent and blew one of its fuses, a decent chance most things were protected. Unlikely that high voltage managed to get through the VRMs.

Assuming the liquid was isolated to the PSU, anyway.

Unfortunately, given the facts of the situation, there's a decent chance that more than the PSU was damaged. If this was a case with the PSU mounted at top or as in many of the modern cases, off to the side in its own little nook, there's a reasonable possibility that the PSU was shorted quickly and the rest of the PC survived. If the water had to pass through a lot of other things to get to the PSU, the chances increase quite a bit.

Really, the only way you'll know is testing witha known working PSU. I would certainly open the PSU to make sure it's dry inside; you don't want it to merely seem like the other parts are try, you want to know that they are!

I see.. My dad said something blew and prolly the fuse does its thing (i hope so). Is it repairable if that's the case? Is the fuse replaceable just like other non pc power supply?

My psu is mounted underneath my motherboard. Water dripped next to my PC and got it wet from the splash.

There are high voltage capacitors inside PSU.
Do not try to fix it. This can have a lethal outcome.

Got it.

For future reference. These are typically fuseable resistors, and not simple fuse/fuseholder arrangements. So soldering equipment is needed and a specialty order for a replacement part.

The high voltage capacitors can remain charged for weeks, particularly if damage has occurred and bleed resistors are no longer in circuit. There is enough power in a typical ATX PSU capacitor to stop the heart.
