Question PSU Calculations

[msalah]

If PSU calculators say that my build needs 350w
then recommends a 850w PSU
i think it's a big headroom for my build
my question is what is the actual PSU wattage needed for the build to work very fine and handle all power spikes ?
Build:
MB: Asus Prime H510m-k
GPU: AMD Rx5600xt
CPU: i5-11400F
HDD : 2x7.2 HDD
SSD: 1xM.2
1xSata SSD

if you're working with a base level AM RX5600XT, I'd go with a 650W PSU and not look at a PSU calculator, then call it a day. If you did add more wattage, you actually add headroom and increase the possibility to hold onto the unit for a longer period of time.
