Hey everyone, I'm in a bit of a bind here. I was just cleaning my desk as usual—using a spray and cloth to wipe down the surface and even cleaned under my PC case and the glass panel. Now, my computer won't turn on at all! It was working fine just a few hours ago. I've unplugged it from both the mains and the PSU at the back and waited about seven hours before trying to power it up again, but still nothing. There are no fans spinning or lights coming on. I'm considering waiting another 24 hours before trying again. Here's the spec list in case it helps: Corsair RM850X PSU, Intel i9-12900K CPU, two 980 PRO SSDs (1TB and 2TB), RTX 3080 graphics card, 32GB Dominator RAM, NZXT Kraken cooler, and an NZXT Z690 motherboard. I'm worried it might be a PSU issue and am thinking about replacing it. Any advice or tips on what I should check to get this thing running again would be greatly appreciated. Thanks!

First, check if you accidentally flipped the switch on the back of the PSU while cleaning. It might seem simple, but it’s worth checking! Sometimes that little switch can be easily bumped. If you did, just flip it back and try again.
Let's tackle this step by step. First off, confirm if the outlet you're using is working. Try plugging in something else, like a lamp, to ensure it’s supplying power. If that’s good, open up your PC case and reseat all the power cables. Make sure everything is tight, especially the 24-pin connector and CPU power cable. If you have a modular PSU, check at the back to see if any cables have come loose. These issues can be sneaky!
I tested the outlet, and it's working fine since my lamp turns on. The PSU is modular, but I didn’t notice any loose cables since nothing was physically moved during cleaning.
I didn't touch the switch when cleaning, but I did flip it in panic later. Unfortunately, it didn't help.
