The CROSSHAIR VIII HERO (WI-FI) shows us the goods with the heat sinks removed!
The VRM is in a 14+2 phase configuration, which is achieved by doubling the number of power stages per each PWM phase, so in this case, the IR35201 (custom labeled on the rear of the motherboard) is in 7+1 phase mode. There are no doublers, and ASUS claims there is a benefit in not using doublers here since it should improve transient response. The IR3555 60A PowIRstages are used to power the CPU; even the SoC phases use the high current 60A part.
The memory VRM is controlled by a Digi+ ASP1103, and the MOSFETs are the same PowerPAKs as we have seen for minor rails on previous Crosshair motherboards, and we have a two-phase configuration for the memory.
