Voltage Converters: Asus The Economizer

This picture shows a bus controller with four switch transistors. This is Asus A7M266's two-phase-controller.

This picture shows a bus controller with six switch transistors. This is Gigabyte GA-7DX's three-phase-controller.

When you compare the three candidates' bus controllers, you will notice a serious difference: Asus A7M266 is equipped with a less elaborate two-phase-controller while Gigabyte and Biostar rely on a three-phase-controller. The advantages of a three-phase-controller lie in the significantly lower heat production at high voltages.
