A:Answer Buy a modular power supply of 750 watts. That should cover everything in this computer. Buying a modular PSU will allow you to only run the wires that are needed oppose to having a bulk of wires that are unused. There are also programs on-line that will calculate for you the power supply minimum requirements for the system you want to build or have. The GPU is the item that requires a lot of power so think of that if you ever want to upgrade. I have a EVGA NVIDIA GeForce RTX 3080ti FTW3 Ultra gaming 12GBGDDR6X WITH ICX cooling sensors that uses 400 watts just by itself! After the online calculator did its thing, my system required 1000 watts minimum, so I invested in a ASUS ROG 1200 with digital display.
