Power Draw Tests, Test System Specs

Measuring Energy Efficiency

Energy efficient computers are a good thing, so it helps to know how power efficient, or power hungry different parts of a computer are when stressed with different tasks. Since it is very difficult to isolate a videocard or CPU and measure power draw separately, PCSTATS measures total system power draw with the aid of an Extech 380803 AC Power Analyzer and A-PFC compliant PC Power and Cooling 750W power supply. The meter is placed between the 120V AC outlet and the PC power supply. By stressing the test platform's graphics solution or processor, it's then possible to measure power draw relative to the PC at an idle state.

The test system is measured at Idle (Windows desktop), Graphics Loaded (3Dmark06) and CPU Loaded (Prime 95) states.

Since it's packing a Phenom II 955 Black Edition, the Gigabyte GA-MA785GMT-UD2H still has a fair amount of power draw at idle, and that number will grow a bit when a graphics card is added in. When the system is put under 3D load, the IGP draws 35W over the normal load, which is quite convservative. Pairing a system like this up with a 3D graphics card is also possible, as long as your power supply is rated for at least 400W.
