MSI PRO B650M-A Performance Review
The MSI PRO B650M-A comes with a basic VRM configuration, providing 55 A across 8 phases. It is designed for entry-level to mid-range low-wattage CPUs. Overclocking or using high-wattage CPUs may lead to thermal issues or potential damage. This board is recommended for budget builds or users with modest performance needs.
This motherboard includes an entry-level audio chipset — Realtek® ALC897 — which provides basic sound quality suitable for casual use. While it’s acceptable for everyday tasks such as web browsing, video playback, and light gaming, it may not meet the expectations of users with mid to high-end audio setups. Audiophiles and those seeking high-fidelity sound should consider using a dedicated sound card or external DAC.
This board delivers balanced value with a performance-per-price ratio of 54.6%, offering a solid blend of features, quality, and affordability.
