GIGABYTE AMD X570 Aorus Motherboard VRM Guide (Page 5)

The X570 Aorus Pro WIFI


The GIGABYTE X570 Aorus Ultra and the Aorus Pro/WIFI have the same VRM component design. They each have 12+2 phases utilizing IR digital power componentry. Both of them also have a 6-layer PCB, which is more than enough.

Like the Ultra, the Pro WIFI features a direct touch copper heat pipe with a copper fin array. The move from a solid heat sink to one with copper fins has been one of the things GIGABYTE has been doing quite right compared to most of the competition over the last few years.

The Ultra features the 5W/mK thermal pads, but here we have normal ones. In this case, we don't have any issues with performance. We can also see how well the thermal pads make contact with the components, as you can see the imprint of the PowIRstages on the thermal pads.

In between the X570 I Pro WIFI and the Master, the Pro WIFI offers an 8+2 pin power connector. While you only need to use the 8-pin connector, the option is there is you want to pump another 150W into the CPU VRM.

While we don't find the same power stages as the other X570 motherboards we have covered, we do find PowIRstages. We find 12 IR3553 40A power stages for the main CPU VRM. These are more than enough for the main CPU VCore VRM. For the SoC we get PowerPAKs, in a 2-high/2-low configuration. Most times, you find a 1-high/1-low configuration, as that's all you need for a full powerstage, but GIGABYTE doubled that count to improve performance for the SoC rail.

GIGABYTE is utilizing the IR digital PWM controller, the IR35201, in a 6+2 phase configuration. It uses IR3599 doublers to double up the phase count. Instead of just using one PWM channel and routing it to two phases, they are producing two separate PWM channels from one from the PWM controller.

Final Thoughts

In the end, GIGABYTE's X570 motherboard line up is extremely impressive when it comes to VRM power delivery.

Any of the motherboards covered here will be more than enough for anyone who wants to overclock their 16-core 3950X.

GIGABYTE purposefully over-engineered the VRMs and cooling for longevity and performance, and we are quite impressed with the four motherboards mentioned in this guide.
