I'm considering using a 750W power supply, specifically the Corsair RM750E ATX 3.1 model, to power my setup with a 9070XT. Is this safe, or should I upgrade to an 850W model instead? My CPU is a Ryzen 5 9600X, so I'm wondering if the 750W will be sufficient for my needs.

I've been running a 9070XT on a Corsair 750W SFX power supply, and it's been working fine with a low TDP CPU. You'll probably be okay with your setup, but going for an 850W would give you a bit more peace of mind.
Yes, definitely use your 750W PSU. The ATX 3.1 certification means it can handle power spikes pretty well. Your setup should be well within the limits unless you're running something really power-hungry, like a heavily overclocked processor.
Just make sure to get a 2x8 pin model since the RM750E doesn’t come with a third 8-pin. However, it's good to know that the 12VHPWR adapter is included with your PSU!
Honestly, a 750W should be totally fine for your setup. Even with the Ryzen 5 9600X, you'd likely do okay with just a 650W. The 9070XT generally only draws around 350W at most.
