A lot of the APU's use 100W. And if you get an unlocked model and intend on overclocking you will likely use even more than 100W.
Ah. I didn't realize the APUs used that amout of wattage. That would explain it, then. Thank you. But that raises another question...
100W divided by 12V = 8.33A
Even a tiny #20 AWG conductor is rated at 11A for chassis wiring: http://www.powerstream.com/Wire_Size.htm
And most power supplies use much larger wire size than that for their CPU power cables. Add to that, the fact that the std 4 pin
socket has 2 pair
of these. Doubling that number as in the example I showed would seem to be overkill. Not that I'm complaining about getting the extra capacity... just curious.
