>after everything is clean
It still looks fucking disgusting

Get a new power cord, if it doesn't work then yes

I agree, lol. I meant everything inside the PC. I couldn’t be bothered to clean the outside, but you motivated me to do it, so thanks.

Got it, I’ll try that tomorrow. Although my worries are more about the PSU blowing up or the rusted part causing a fire or something like that, rather than it just not working...

Clean the rust first, scrape it with a knife or something. Then use isopropyl alcohol (don't use water). Let it dry and pray it works perfectly.

A damaged power cord causing arcing on connection is damn unlikely, unless the psu-end plug is visibly completely ruined. The plug design makes it almost impossible for a *small* fault to cause this result.

The PSU committing sudoku if definitely possible, but if it's going to do that is already beyond rescue anyway. If it does that it will likely blow a capacitor or something, which looks and sounds dramatic but isn't actually dangerous.

Causing fire is a real risk. When there is actual arcing there is great heat development; there is nothing flammable enough in a PSU to cause fire *quickly*, but it might develop it if you try to ignore the problem and just run with it while it's making crispy sounds. It is a bit strange that you didn't end up blowing a circuit breaker, arcing in the plug is a sign of a short circuit and should definitely blow the breaker. But it could be arcing and a short circuit somewhere inside the PSU, which has a good of wrecking the PSU without triggering the breaker.

Another risk to consider is that a broken power supply might damage other components in your computer. This is not common when a power supply is visibly fucked; it tends to be a risk that applies more when a PSU is *subtly* about to give the ghost, not so much when it's visibly about to blow. But still, not a risk you want to take.

My recommendation is that you wait 24 hours (maybe moisture ended up in the PSU somewhere somehow), and then take your PSU out of your computer entirely. Plug it in somewhere far away, possibly outside, with a new cable. If it still arcs, toss it out and buy a new one. If it seems fine, activate the power supply by connecting the green wire in the ATX connector to any black wire with a paperclip (look it up for details). If it still works, you can reinstall it into your computer.

you left it wet and plugged it in
RMA and dont say you did that, that it just did it by itself randomly
if you cant, buy a new psu unless you want to gamble with it frying the rest of your components or your house

bro that prong has fucking rust on it, how does that even happen.

I can tell you're a fucking slob just by looking at how you keep your PC power socket and the other minimal picture data in that shot. Just throw it out and get another one to trash. You obviously can't keep things nice so you have low self control. Stop eating frozen pizzas and guzzling pop for a while to save up money to buy a used replacement. You may actually lose a few pounds.

There is no way in hell this was a good quality PC so you should have no problem going to a thrift store or online classified site to find a low tier shit quality PC again to fuck up once more. Maybe a tablet is more your style, loser? I'm actually surprised you have access to the Internet still to post your bait.
