Re: how many W a PSU for non-gaming Debian?



Unfortunately the motherboard was worst-case 166.2 W, not the
previous estimate/approximation at 80.

The 166.2 (motherboard W really doesn't include the CPU?)

So no it says it is is worst-case 277 W, and with +30% wiggle
room it is 361 W :(

back to passive 400W I guess ...


  device  model/category                     max W   note               ref

  fans     80 mm (3K RPM)                      9     3*3W =  9W
          120 mm (2K RPM)                     12     2*6W = 12W        [ii]

total:

with +30% wiggle room:
