I'm finishing up a new PC build and want to confirm whether my 750W power supply will be sufficient. Here's what I've got:
- CPU: 7800x3d
- GPU: 9070xt
- RAM: 32GB DDR5 Crucial OC
- Storage: 2TB WD NVMe and 4TB WD HDD
I've used a Corsair 750W Bronze in my previous build, and PCPartPicker estimates the power requirements at around 605W. Since I'm not planning to overclock any components, is having 150W extra headroom enough? Thanks for your insights!

Based on your specs, 605W already includes some overhead, so your system will likely pull less than 450W most of the time. As long as your 750W PSU can handle the transient loads from the 9070 XT, you should be in good shape! Just make sure your PSU is reliable.

My current PSU is a Corsair CX750M Semi-Modular 80 PLUS Bronze and it's just over two years old.
