Hey everyone! I'm currently running a pretty powerful setup with an Intel Core i9-13900KF, an AIO thermalright 360mm cooler, an ASUS Prime B760M-A WiFi D4 motherboard, 32GB of DDR4 3600MHz Corsair Vengeance LPX RAM, and an NVIDIA GeForce RTX 5070 12GB graphics card. My power supply is a 750W Be Quiet! System Power 11 M with an 80+ Gold rating. I'm wondering if this power supply can handle an RX 9070XT without pushing it to its limits. What do you all think?

Your powerful CPU will compete with the GPU for power, so it might get close to the limit. If you want to ensure better stability and room for future upgrades, I’d really suggest going for at least an 850W PSU.
It's crucial to look at just how much power your 13900KF pulls. It might not hit the maximum under normal conditions, especially considering that the motherboard VRMs aren’t built for heavy loads. Your PSU is ATX 3.x, so it can handle short spikes, but pushing close to 700 watts under full load might still make things sketchy. It’s possible to undervolt both your CPU and GPU to keep performance without maxing out the power supply.
Yes, your power supply can manage things, but I'm a bit concerned about the i9 CPU since it could draw a lot of power, especially when overclocked. Just keep an eye on the power draw!
