ASUS P8Z68-V PRO Motherboard
Voltage Regulator
Contents
The CPU voltage regulator circuit of the ASUS P8Z68-V PRO has 12 phases for the CPU main voltage (Vcc a.k.a. Vcore), two for the CPU VTT voltage (integrated memory controller and L3 memory cache), and four for the CPU VAXG voltage (integrated video controller). Therefore, it uses a “12+2+4” configuration.

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