Corsair SF750 is OK.

Been using this for years, no complaints

Hey there! If you're looking for the best PSU for the Radeon RX 9070 XT, I'd recommend going with a 750W or 850W 80+ Gold certified unit from a reputable brand like Corsair, Seasonic, or EVGA. The RX 9070 XT is a high-performance GPU, so you'll want a PSU with stable power delivery and enough headroom for overclocking or future upgrades. Personally, I'm using a Corsair RM850x, and it's been rock-solid so far!

Honestly I've had a pretty rough time trying to find the sweet spot for the 9070 XT. I thought I was being smart by reusing my old power supply since it was technically enough wattage, but unfortunately the reality was a lot more headache-inducing. It kept tripping the safety stuff during peak loads and just shutting everything down in the middle of a game. Not exactly as good as I expected from a high-end build... it was basically a nightmare for weeks. I learned the hard way that these newer cards have such weird power spikes that you really cant cut corners on the quality or age of the unit. My current setup is finally stable now that I overbought on capacity, but man, those early crashes really sucked the fun out of the new GPU hype. Just dont settle for the bare minimum if you want to actually enjoy your rig without wondering if itll die every time a scene gets busy.

A 750W PSU is OK.

TGP for 9070 XT?

750W or 850W PSU is OK.

750W PSU can works.

650W will be fine for 9070XT. And if you got the 750W, of course it is better.
