ASUS Maximus VI HERO Motherboard

Voltage Regulator

The CPU voltage regulator circuit of the ASUS Maximus VI HERO has eight phases for the. The voltage regulator is controlled by ASUS DIGI+ ASP1251 chip, which uses a digital design. Each phase is driven by a CSD87350Q5D integrated circuit, which incorporates the “low side” and “high side” transistors. This integrated circuit provides efficiency above 93%, as it can switch at up to 1.5 MHz (usually voltage regulator circuits operate at 250 kHz or 1 MHz).

The ASUS Maximus VI HERO uses high-end solid, Japanese electrolytic capacitors, from Nichicon, on its voltage regulator circuit (a.k.a. “10K Black Metallic 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). This allows you to use liquid nitrogen on your CPU without damaging the capacitors.

All coils on this motherboard are high-end models with gold-plated cores. According to ASUS, these coils support up to 60 A.
