I'm wondering if my power supply is enough for my setup. I've got a 9070XT Mercury OC Edition that pulls around 360W under load, along with a 7800X3D processor. My build includes 32GB of 6000 CL30 RAM, a 500GB NVMe SSD, a 1TB SATA SSD, an AIO cooler, and a B650 Tomahawk WiFi motherboard. I also have four 140mm case fans. My power supply is the XPG CORE REACTOR II VE 750W. Do you think that's sufficient?

I've used a 750W PSU with a 3090 and 9850x3D without any problems, even with a case filled with nine fans and an AIO cooler. So, it sounds like your setup should be fine too, as long as your PSU is reputable.
It should work fine, but I recommend undervolting your GPU and adjusting the power limit in AMD Adrenalin. Some users found that the 9070XT can draw only about 250W when optimized, which can keep things cooler without much impact on performance.
750W should be adequate, especially since the Core Reactor II is a modern PSU with ATX 3.1 support, which helps manage power spikes from modern GPUs.
Check out a PSU calculator on a hardware manufacturer's website to see if you're in the safe zone, but just remember they often suggest more wattage than you actually need.
Absolutely, it looks good to me! If you're concerned, try undervolting or setting a power limit just to keep it all running smoothly.

Yeah, those calculators tend to overestimate to be on the safe side.
