The X399 Professional Gaming reveals its goods when we remove the heat sinks.
We get a true 8-phase VRM controlled by an International Rectifier IR35201 working in 8+0 mode. It's a fully digital cutting edge PWM and controls eight IR3555 fully integrated power stages rated at 60A each. While that is all good and dandy, we also need to find high current chokes, and ASRock uses 60A rated ones. The capacitors are tantalum POSCAPs located on the back of the PCB. ASRock also uses a 2oz copper PCB, making it easier to cool the VRM area.
We find another IR35201 digital PWM, but only three of its phases are being utilized to power the SoC VRM. The SoC VRM uses three IR3555 PowIRstages. Each memory VRM uses a UPI Semiconductor uP1647P PWM to control and drive two SinoPower SM7341EHKP dual N-Channel MOSFETs.
The second VRM is pictured above and its identical to the other memory VRM.
