Written analysis

ASRock B860M H2 at a glance

The ASRock B860M H2 uses the Micro-ATX form factor, LGA 1851 socket, and B860M chipset. This is a balanced mainstream platform: enough expansion and connectivity for a performance PC without paying only for flagship extras.

Memory support is DDR5 across 2 DIMM slots, with up to 128 GB and rated overclocked speeds up to 8333 MT/s. XMP / EXPO memory-profile support is recorded for easier tuning.

Best fit: a mainstream gaming, home, or office system with moderate expansion needs.

Power delivery

The calculated VRM score is 14.0, placing the power delivery in the basic class. The board lists 5 CPU power phases, 60 A power stages in a 5+1+1+1+1 layout. CPU power input is listed as 1. Keep it paired with lower-power processors and avoid sustained overclocked loads.

Expansion and storage

The expansion and storage score is 54.0: focused on the essentials. The platform supports PCIe 4.0. Physical expansion includes 1 ×16 slot, and 2 ×1.

On-board storage consists of 2 M.2 slots and 4 SATA ports. Supported M.2 lengths are listed as 2280. The two-slot layout covers a typical OS-and-games or OS-and-project-drive setup.

Connectivity and rear I/O

The connectivity score is 32.0, rated essential. There is no recorded onboard Wi-Fi ; wired networking is - Gigabit LAN 10/100/1000 Mb/s - Realtek 8111H at up to 1000 Mbps. The recorded USB provision is 6 rear connections and 7 front-panel connections. The specification sheet below separates every USB speed and connector type.

Display connectivity includes HDMI 2.1. These motherboard outputs require a processor with integrated graphics.

Audio

The audio score is 40.0. This is a standard onboard solution using Realtek ALC897 Audio Codec. It covers normal gaming and communication; demanding headphones or production work still benefit from an external interface. The rear panel has 3 analogue jacks.

Buying verdict

Overall quality is 40.40, a basic but usable result for office, media, and budget gaming systems.

At the recorded Amazon price, the quality-to-price score is 85.3—an excellent value relative to the other boards in the catalog.
