Dual-Stack MOSFET (DSM)
Closeup of the ASRock z390 motherboard's dual-stack MOSFET

Dual-Stack MOSFET (DSM) is another innovative MOSFETs design by ASRock. The silicon die area is increased by stacking two dies into one MOSFET. The larger the die area, the lower Rds(on). Compared to traditional discrete MOSFET, DSM with larger die area provides extreme lower Rds(on) 1.2mO, so the power supply for the CPU Vcore is more efficient.

Combo Caps
