Z390 Motherboard vrm topic

Asrock:

Asrock Z390 Taichi.

The vrm on this particular board isnt really something new.
Its very similar to what we have seen on Asrock boards before.

Main vrm:

  • PWM: IR35201 which runs a 5+2 phase mod configuration.
    5 phases are being doubled to 10 using IR3598 phase doublers for Vcore.
    And the +2 phases for the igpu are straight phases no- doubling.

  • Mosfets / powerstages: Texas instruments CSD87350D 25A / 40A Ti-nexfets.

  • inductors: 60A.

  • Caps: 12K.

Vccsa and Vccio get their power from single phase vrm´s controlled by a Richtek RT8120.
And using Sino power SM7341EH Dual-N fets.

Memory vrm:

  • The memory vrm is a two phase configuration controlled by a uPi semiconductor uP1674 pwm.
    And using the same Sino power SM7341-EH Dual-N fets.
