Sapphire Radeon HD 7770 FleX GHz Edition 1GB Graphics Card Review

To test power consumption, we monitor the overall power of the system through a plug-in electricity usage monitor at an idle and load state. This allows us to show the fluctuation between how much power draw the graphics card takes at idle and at load. By monitoring the overall usage of the whole system, it gives an easy comparison if you wish to do the same yourself as opposed to buying very expensive individual testing equipment.

Power consumption is another area where this card really did shine, with very low results of 125 Watts idle and 186 Watts load with only the 7750 Pro utilising less power though the reference 7770 XT wasn’t too far behind, followed by some other 7770’s from a variety of brands.
