ASUS VANGUARD B85 Motherboard
Voltage Regulator
Contents
The voltage regulator of the VANGUARD B85 has four phases for the CPU. It is controlled by an ASUS DIGI+ ASP1253 chip, which uses a digital design. Each phase uses a NFMFS4955N and a NTMFS4737N MOSFETs.

The ASUS VANGUARD B85 uses high-end solid Japanese electrolytic capacitors on its voltage regulator circuit (a.k.a. “10K Capacitors”). According to ASUS, these capacitors have a lifespan five times longer than regular Japanese solid capacitors, and have a higher temperature tolerance (between -55° C and +105° C, making them military-grade components). The coils are ferrite models.
