The VRM here is one of the largest we have seen on any X299 motherboard, ASUS even moved the socket down to fit in all the power stages. This 16 phase VRM is a beast, and meant for Intel's 9980XE and other really high power CPUs that can draw over 1kw under LN2. It is controlled by an IR35201, which is relabeled ASP1405I. There are 16 IR3555M, which are 60A PowIRstages, and no doublers are used so each power stages attaches to one PWM channel from the PWM, this improves transient response.

The CPU VRM gets its power from two 8-pin power connectors. The VCCSA gets its power from two On Semiconductor NCP302045 DrMOS rated 45A, and is controlled by another ASP1405I.

Each memory VRM uses the same On Semiconductor DrMOS, but they are controlled by the ASP1250.
