55W for motherboard/peripherals/CPU AND GPU!!! Nice.
Even my least energy hungry 7770 card uses over 70W on it's own when being overclocked (undervolts) and my 7950 uses wayyyyyy more.
A 55W rig would be great for linking into a solar set-up on the shed roof. Mine only when the electric is free

What is the motherboard? A single board computer with PCIe socket?
