Now I will look at the parts on the motherboard.
The VRM on this motherboard uses International Rectifier PWMs and power stages. The CPU VCore is a true 4-phase setup while the iGPU is a true 3-phase setup. Each phase gets its own 50A IR3556 integrated PowIRstage and Vitec 45A inductor. Supermicro has focused heavily on power density, and these are very high power components. The board uses two IR35203 6+1 phase digital PWMs to power each set of phases.
The memory VRM consists of a single phase powered by a Primarion digital PWM (PX3143HDM), and a Fairchild semiconductor integrated power stage (DF22CJ). The VCCSA gets its power from a single phase IR3556 integrated power stage which is controlled by the second output of the CPU core PWM.
