ASUS P8H67-M PRO/CSM Motherboard
Voltage Regulator
Contents
The CPU voltage regulator circuit of the ASUS P8H67-M PRO/CSM has four phases for the CPU main voltage (Vcc a.k.a. Vcore), one for the CPU VCCSA voltage (integrated PCI Express controller and memory controller), and one for the CPU VAXG voltage (integrated video controller). Therefore, it uses a “4+1+1” configuration.

This motherboard uses solid capacitors and ferrite-core coils, which provide less energy loss, improving efficiency up to 20 percent. However, only half of the transistors come with a passive heatsink installed, as you can see in Figure 8.
