Building on the earlier suggestion, I feel your pain. I had a rough time last year with a unit that sounded solid on paper but ended up dying on me mid-game during a 4K session. It was super frustrating because like you, I really just wanted to game. Unfortunately, some of those mid-tier options arent as good as expected when you hit them with the massive transient spikes that a 4090 pulls. If you want peace of mind, you really gotta prioritize high-quality capacitors. I ended up swapping to the be quiet! Straight Power 12 850W ATX 3.0 and it has been rock solid. Its basically silent and I havent had a single crash since installing it. Another solid pick if you can find it is the MSI MPG A850G PCIE5 850W Gold Fully Modular. Honestly, these units are just built differently. Dont mess around with cheap power supplies when you have a card that expensive. Save yourself the headache, grab a reputable ATX 3.0 unit, and enjoy your week off. Its worth spending the extra cash now rather than dealing with a toasted GPU later. You definitely dont want to risk that hardware!

> I saved up forever for this RTX 4090 and I cant even play for an hour without the whole thing cutting to black. Man, reading that makes me nervous for your card! I had a cheap power supply pull that same stunt years ago on a much smaller build, and it actually fried my PCIe lane. Since then, I do not mess around with budget units. If you want something rock solid that comes with the 12VHPWR cable natively so you dont have to deal with those nasty adapters, look at the MSI MPG A850G PCIE5 850W Gold Modular. I swapped to this exact unit a few months back and honestly, it is amazing. It handles the transient spikes from the 40 series cards like a champ, and the build quality is just fantastic compared to the budget junk you see on Amazon. It feels heavy, the cables are decent, and I havent had a single hiccup since installing it. Honestly, for around 150 bucks, it is a no-brainer. Just swap it out before you plug that beast of a card back in, okay? You really dont want to risk a short taking out your mobo or GPU. Good luck with the Cyberpunk playthrough, it looks stunning at 4K!

> I saved up forever for this RTX 4090 and I cant even play for an hour without the whole thing cutting to black. That sounds like your current unit is tripping its OCP because of the transient spikes an RTX 4090 pulls. Honestly, 850W is the absolute floor for that card, so you need something with really high quality components so it doesnt choke under load. If you want to stay near that 200 dollar mark and get something reliable, I would look at the Corsair RM850x 850W Gold. It is legendary for a reason. The build quality is solid and it handles transient spikes better than the RMe series because it uses better Japanese capacitors and has a quieter fan profile. Another great option is the Seasonic FOCUS GX-850 850W Gold. Seasonic makes some of the most stable rails on the market, and that unit comes with a long warranty which gives you some peace of mind. Whatever you pick, just make sure you use the native 12VHPWR cable if you can, rather than the adapter that came with your card, to avoid those melting connector issues everyone talks about. Since you have a week off coming up, grab one of these ASAP so you can actually game instead of troubleshooting crashes. Just dont cheap out on the power supply again, especially with a card as power-hungry as that one.

Honestly man, just ditch the cheap unit before it takes your 4090 with it. I had a similar scare a few years back where a budget unit fried my motherboard, and since then I only trust top-tier internals. If you have 200 bucks, look at the SeaSonic Vertex GX-850 850W Gold ATX 3.0. It is rock solid and supports that new 12VHPWR cable directly so you dont need to mess with those sketchy adapters that melt. Another solid option is the Corsair RM850x 850W Gold Fully Modular. Its been the gold standard for years and honestly, the noise levels are basically non-existent. Just make sure whatever you pick is ATX 3.0 compliant. Dont skimp on the cables either, plug that sucker in tight or you are gonna have a bad time.
