ASUS P8Z77-V DELUXE Motherboard
Voltage Regulator
Contents
The CPU voltage regulator circuit of the ASUS P8Z77-V DELUXE has 16 phases for the CPU main voltage (Vcc a.k.a. Vcore), two for the CPU VSA voltage (memory controller), two for the CPU VTT voltage (PCI Express and DMI interfaces), and four for the CPU integrated video controller (VAXG). Therefore, it uses a “16+2+1+4” configuration.

The voltage regulator is controlled by ASUS’s Digi+ EPU (ASP1000C) integrated circuit, using a digital design.
The ASUS P8Z77-V DELUXE uses solid electrolytic capacitors. All coils on this motherboard are ferrite-core models, which can provide up to 20% improvement in efficiency.
