Power Consumption

We measured the power consumption of our testbed equipped with different graphics cards using a multifunctional Zalman ZM-MFC3 panel which can report how much power a computer (without the monitor) draws from a wall outlet. There were two test modes: 2D (editing documents in Microsoft Word or web surfing) and 3D (four runs of the introductory “Swamp” scene in Crysis 3 game at 2560x1440 with maximum image quality settings, but without MSAA).

We are going to compare the power consumption of ASUS ROG MATRIX 7970 with that of HIS 7970 IceQ X² GHz Edition, ASUS GeForce GTX 680 DirectCU II TOP and NVIDIA GeForce GTX TITAN:

The ASUS ROG MATRIX 7970 system needs a little more power than the system with the HIS Radeon HD 7970 GHz Edition. The difference is only 20 watts at peak load. The overclocked GeForce GTX 680 from ASUS needs 10 watts less than the HIS-based configuration whereas the Nvidia GeForce GTX Titan turns out to be economical and consumes only 23 watts more than the ASUS ROG Matrix 7970 configuration. By the way, notwithstanding ASUS’s recommendations, a computer with ASUS ROG Matrix 7970 can be powered by a 550-600-watt PSU even if it’s got a well-overclocked CPU.
