GIGABYTE X570 Aorus Master (AMD X570) Motherboard Review (Page 3)

Circuit Analysis


The X570 Aorus Master shows us the goods with the heat sinks removed!


The VRM is in a 12+2 phase configuration, and it's a true 12 phase that doesn't utilize doublers, the new Infineon digital PWM controller supports up to 16 true phases. GIGABYTE states that by using a true 12 phase VRM compared to other that don't use true phases, they gain 4% efficiency.

While that might not sound impressive, it's the same difference between 80 Plus Silver and 80 Plus Platinum power supplies, so it's a bigger deal than you might think. Both the CPU VCC and SoC VRMs use International Rectifier 50A IR3556 PowIRstages, and are controlled by the Infineon XDPE132G5C digital PWM controller.


The memory VRM is a single-phase controlled by an RT8120D PWM controller and PowerPAK MOSFETs in a two low-side one high-side MOSFET.
