Hardware Unbox, a popular channel at Youtube recently tested the VRM quality of a number of $200 AMD X570 based motherboards. The boards in no particular order are the ASUS TUF Gaming X570 Plus, Gigabyte X570 Aorus Elite, ASRock X570 Steel Legend and the MSI MPG X570 Gaming Edge WiFi.
Before the test proceed, Steve provided a VRM design overview of each motherboards. Other brands were using phase doublers, while the TUF Gaming board from ASUS uses a more traditional approach. ASUS just tripled everything for each phases rather than adding a doubler IC on top of the power stages.
Other stuff that Steve checked out is also the physical design of each motherboard’s VRM coolers. The MSI MEG X570 Godlike for example, which is one of the best his recent top-end VRM tests features a heat-pipe enabled design. Similar to that of the MEG X570 Ace we’ve tested before.
The initial test with the Ryzen 9 3900X showed that the Gigabyte X570 Aorus Elite performed the best with a 57ºC MOSFET and 63ºC backside temperature. The MSI motherboard performed the worst here with scorching hot values.
At 4.3GHz with 1.4v at the vCore, the ASUS TUF Gaming X570 Plus took the top spot with the best temperature output. The MSI board on the other hand is still the worst out of the bunch.
Finally, we get to see how the sub $200 USD motherboards stack up with the rest of Steve’s tested X570 motherboards. The ASUS TUF Gaming motherboard with a true 4 phase design sure is a budget champ by the looks of it.
Clearly, the tests done by Hardware Unboxed shows that a simple 4 phase VRM could match or even beat motherboards with higher phase counts. Quality over quantity I suppose is still the name of the game when it comes to components. Shocking.
