ASUS Maximus IV Extreme Motherboard

Voltage Regulator

The CPU voltage regulator circuit of the ASUS Maximus IV Extreme has eight phases for the CPU main voltage (Vcc a.k.a. Vcore) and two for the CPU VCCSA voltage (integrated PCI Express controller and memory controller). Therefore, it uses an “8+2” configuration, using a digital design.

This motherboard uses military-grade components, including
solid ferrite-core coils, which present less energy loss than iron-core coils (i.e., they improve efficiency), solid capacitors, and high-end, low RDS(on) transistors (i.e., higher efficiency).

While most motherboards use a two-phase design for the memory voltage regulator, the ASUS Maximus IV Extreme uses a three-phase design.
