搭載DrMOS的板子在低負載下小贏對手，高負載下則是大輸（高負載下對手不用開省電機制都把DrMOS的轉換效率完全壓制住）：

Despite sparingly sipping power at idle, the MSI board has nearly the highest power draw of the lot under load. The GD70's relatively modest 4+1 power-phase arrangement looks to be considerably less efficient when all six of our Phenom's cores are fully utilized.

Of the three 890FX boards, the Asus clearly has the lowest power draw under load. You don't even need to bother with Asus' EPU software, which at best only knocks off a couple of watts. Gigabyte's EasySaver app, on the other hand, shaves a good 20W off the UD7's power draw under load. If only those power savings could be realized without keeping the EasySaver app running in the background.
