Overview
MSI's Gaming Plus variant covers the same AM4 Ryzen 5000/4000 G/3000 series range as the PRO board, but adds Core Boost VRM tuning, Frozr cooling hardware and a second M.2 slot alongside Wi-Fi 6E.
Where the PRO B550M-P leans toward simple business builds, this Gaming Plus board adds Frozr thermal hardware, including an M.2 Shield Frozr heatsink and a pump fan header, aimed at keeping components cooler under sustained gaming loads. Dual M.2 slots, one Gen4 and one Gen3, give more fast-storage room than the single-slot PRO board.
- Dual M.2, Gen4x4 and Gen3x4
- Core Boost VRM technology
- Wi-Fi 6E and Bluetooth 5.3
- M.2 Shield Frozr heatsink
Who it's for
Suits AM4 gamers who want two M.2 drives, better VRM cooling than a bare-bones board, and current Wi-Fi 6E wireless. Buyers who only need one fast drive and no gaming branding may be better served by MSI's plainer PRO series instead.
Pros and cons
- Two M.2 slots, one Gen4 and one Gen3
- Core Boost VRM plus Frozr cooling hardware
- Wi-Fi 6E and Bluetooth 5.3 built in
- PCIe 4.0 x16 slot with steel armor reinforcement
- AM4 only, no path to newer AM5 CPUs
Performance notes
Core Boost VRM technology targets steadier power delivery under load, backed by thermal pads, an extended heatsink and the M.2 Shield Frozr covering the primary Gen4 M.2 slot to curb thermal throttling on fast SSDs. The Pump-sys fan header is meant for liquid cooling pump control rather than a standard case fan.
