We used a calibrated meter to measure the power at the wall. No monitors were factored into the readings. The system power drain was measured in the following states:
Idle: when resting at the desktop.
Gaming Load: running the ‘combined’ test in 3dMark 11. Processor and graphics card are stressed.
The Wired2Fire Diablo Predator System doesn't require a lot of power at the socket. At idle it demands around 76watts. This rises to around 225 watts under gaming load.
