4. MSI MPG X570 Gaming Plus

Price: $298 | Check Latest Price

The MPG X570 Gaming Plus has a slightly superior appearance to its competitors. The PCB is a mix of black and red, and the heatsinks have a dark grey color scheme.   However, the RGB area is where Gaming Plus falls well behind its competitors in this pricing range. There is no addressable RGB lighting on the board, which is a disappointment for our RGB fans. But, still, you can use RGB fans to illuminate your Ryzen 9 3900X Gaming Motherboard.

The voltage regulator has an 8+2 10-phase architecture and is fitted with an IR35201 PWM controller. MSI employs an expanded heatsink layout for efficient thermal dissipation to keep the VRMs cool. This time, though, there is no heat pipe connecting the two. A Frozr heatsink with a dual ball-bearing fan sits on top of the chipset. Furthermore, the fan uses zero frozr technology, which is an AI tuning mechanism that regulates fan speed based on the heat produced by the chipset while maintaining noise levels low.

Memory is such an area where no X570 board falls short, and this board is no exception. It has four DIMM slots and a memory capacity of 128GB at overclocked speeds of 4400+MHz. This board’s storage options are sufficient, including 6 SATA3 connectors and 2 M.2 gen 4 ports.

However, you may be astonished to notice that there is no M.2 heatsink connected to the board. Worry not, MSI has you covered with its M.2 frozr shield included in the box. The generation 4 lanes additionally have 2 PCIe x16 and 3 PCIe x1 ports.

What we liked:

• Supports DDR4 memory @ 4400 MHz
• Integrated with audio boost 4 technology
