tbh if youre dropping that much cash on a 9950X and a 5080, you definitely want something ATX 3.0 or 3.1 so you dont have to mess with those annoying adapters. i personally think the MSI MAG A1000G PCIE5 1000W 80+ Gold is a killer value right now. it comes with the native 12VHPWR cable which makes cable management way easier for a DIY build. if you want a bit more headroom for future upgrades or just want the fan to stay silent longer, the Thermaltake Toughpower GF3 1200W 80+ Gold is usually priced really well. ive used a few of those lately and theyve been rock solid. plus, 1200W means youre barely pushing the thing even under heavy load. both should be way under your $300 budget, leaving you some extra cash for extra storage or whatever.

Corsair RM1000x. I've run similar setups flawlessly; zero issues in 2023.

Realistically, 1000W 80+ Gold is minimum. Seasonic Vertex GX-1000 handles transient spikes well.

1000W minimum, 80+ Gold. Seasonic's Prime series is overbuilt; be careful of cheap alternatives.

1000W should do it, but Corsair RM850x is often cheaper and works great. Depends on your needs, though!

Hey! For 9950X/5080, don't skimp. 1000W minimum. Seasonic's solid, but their pricing's jumped. Before pulling the trigger, check Corsair's RMx series reviews; sometimes they offer better value per watt. Might want to consider longer warranties – lower long-term cost if things go sideways. Be careful; PSU failures can fry everything!
