The CPU voltage regulator circuit of the ASUS SABERTOOTH Z77 has eight phases for the CPU main voltage (Vcc a.k.a. Vcore), one for the CPU VSA voltage (memory controller), one for the CPU VTT voltage (PCI Express and DMI interfaces), and four for the CPU integrated video controller (VAXG). Therefore, it uses a “8+1+1+4” configuration.

The voltage regulator is controlled by ASUS’s Digi+ EPU (ASP1000C) integrated circuit, using a digital design.

The ASUS SABERTOOTH Z77 uses solid electrolytic capacitors. All coils on this motherboard are ferrite-core models, which can provide up to 20% improvement in efficiency.
