Power consumption
The trio of platforms all use the 80 PLUS Platinum-rated Corsair AX760i PSU. Gone are the days of PCs consuming 100W-plus when idling, but the use of a 100W TDP A10-6800K has a negative impact when compared to the 54W Core i3-4330. It's a little surprising to see the Mini ITX ASRock board consuming more than the full-ATX Gigabyte for both 2D and 3D loads, mind.
