I'm planning to build a new PC with the AMD RTX 5090 and I'm unsure about the best power supply unit (PSU) to pair with it. What wattage should I aim for, and are there specific brands or models that are highly recommended? I've heard that the RTX 5090 can draw over 600W, so I want to ensure I choose a reliable PSU that can handle the load. Any advice would be appreciated!

I'm running a similar high-end setup and went with a 1200W Corsair HX1200i. Might seem like overkill, but PSUs are most efficient at around 50-80% load, so you'll actually save money on electricity in the long run. Plus, it gives you room for future upgrades without having to replace the PSU again. The 5090 is going to be a power-hungry beast.

Honestly, I'm kinda cautious about just looking at the base wattage. I think I heard somewhere that these high-end cards are gonna have some pretty wild transient spikes... IIRC, even if the average draw is okay, those micro-second power excursions can sometimes trip the protection on older units. Not sure if the 5090 benchmarks are fully out yet, but you *really* wanna make sure the unit is ATX 3.0 or 3.1 compliant to handle those bursts. Like, real-world stability is about more than just the total capacity. Basically, I'd wait to see some actual stress testing from reviewers to see how it handles *real* loads. I mean... wait no, is it even an AMD card? Anyway, you dont wanna risk your system shutting down mid-game just because the PSU couldn't react fast enough... just my two cents.

Yep, this is the way
