ASROCK B450M-HDV R4.0 Performance Review
The ASROCK B450M-HDV R4.0 comes with a basic VRM configuration, providing 50 A across 5 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 ALC887/897 — 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.
In terms of value, it achieves 89.0% efficiency relative to the best-performing motherboard in its category, making it an excellent choice for users seeking a cost-effective solution.
