Applying the power-consumption handwave estimates from Linux-Fan's larger mail, that would be: > i3-7100T (TDP 35W) supports up to 3 displays up to 4096x2304 35 > 1 2.5" SSD +15 > 2 3.5" Hitachi Deskstars +20 > 1 DVD writer +10 (assuming the same power requirements as a HDD, which seems at least ballpark plausible) > ARCTIC Freezer 7 Pro cooler > 4 fans + some unknown factor. > The calculator showed I'd be using 37% of a 300W power supply, 25% of the > installed 450W PS. 35 + 15 + 20 + 10 is 80. 25% of 450 is 112.5. 112.5 - 80 is 32.5. 32.5 watts for the fans plus the motherboard, and allowing for wiggle room for mis-estimation, doesn't seem terribly unreasonable. > Finding actual power consumption of a motherboard is apparently brutal.
