amix, are you saying you're feeding the 12V power with 5V? That can't be good for it Wink Oh and watts are watts no matter the supply voltage. In fact, if you feed it less than the required voltage, current draw hence power consumption will go up! Not down. Sorry, matey!
Say you who feed a 12v fan 5v from the usb port!
itll draw the current it needs to run, regardless of its supplied voltage. in theory it should go slower.
wiht voltage current CONVERSION as you up/down one the other changes in repect (energy can not be destroy only converted from one form to another - physics 101). so up the voltage ampage goes down. drop the voltage ampage goes up. wiht a conversion, say 12v conversion to 5v conversion - as appears to happen wihtin the grids.
Im not converting 12v to 5v im marly supplying 5v to start with.
and hashing away at 650 - easy break in - its drawing a steedy 0.79A.
At 5v * 0.79A = 3.95 Watts
Compared to 12v at 0.6A (i think but that was just startup never measured the current draw for 650 hash rate!) = 12v*0.6A = 7.2 Watt.
So already its less wattage. oh at startup it pulled 0.47A
5v *0.47A = 2.35 Watts
