Hey everyone, I'm looking for some advice on my current PC build setup. I've got a 9070XT Mercury OC Edition that consumes about 360W, along with a 7800X3D processor. My other components include 32GB of 6000 CL30 RAM, a 500GB NVMe SSD, a 1TB SATA SSD, an AIO cooler, and 4 additional 140mm fans in a B650 Tomahawk WiFi motherboard. I'm using an XPG Core Reactor II VE 750W power supply. Do you think this setup will work fine without any issues?

I've used a 750W PSU with a 3090 and a 9850X3D (previously a 5900X) and had no problems at all. Even with 9 fans and an AIO cooler, it held up well. As long as your PSU is decent, you should be good to go!
I’d say it’ll work well. If you’re worried, undervolting or setting a power limit can help. Better to try that than rush into buying a new PSU!
A modern PSU with ATX 3.1 support is key, especially for handling the power spikes from newer GPUs. Good news: the Core Reactor II VE does meet this requirement, so you should be fine!
You should be fine, but I'd recommend undervolting your GPU and tweaking the power limit using AMD Adrenalin. I’ve seen some 9070XTs pull around 250W under load with those adjustments, which helps keep temps down without sacrificing performance too much.
Check out a PSU calculator on a manufacturer's website to see what you need. Just keep in mind that they often suggest you get a bit more power than necessary.
