What kind of PSU do I need for this PC Build

[Sye]

Hi everyone,

At least 20 years that I made my last build and a lot of thinks change but the base are still there. I come to you because because I'm stuck on one part of my new build and looking for some advise.

Here is the build :
Moterboard ROG Strix X570-E Gaming
CPU Ryzen 7 3700X
HD T-Force Vulcan 1TB and S70 M.2 PCIe GEN3X4 NVMe 1TB
VGA ASUS ROG STRIX GeForce® GTX 1080 TI 11GB OC
RAM G.Skill Trident Z Royal Series 16GB (2 x 8GB) DDR4 3600 MHz CL16
Case CM Storm Trooper SE Black

So my question is what power you will use? 650W-700W-750W or 850W

Thanks for your advise

You can easily get away with a 650W PSU, though you should factor in future upgrades too. If you are looking at eventually getting another GPU or a GPU that draws more Power, you will be happy to have a stronger PSU already. 750W seems like a good sweet spot to me.
