ASUS Prime H810M-A WiFi-CSM Motherboard: LGA 1851, DDR5 and what it offers

The ASUS Prime H810M-A WiFi-CSM is a micro-ATX motherboard for Intel's LGA 1851 socket, built around the H810 chipset. It targets compact, mainstream desktops such as home and office PCs, and it is part of ASUS's Corporate Stable Model line. Here is what its main specifications mean when planning a build.

Socket and processors

LGA 1851 is the socket used by Intel Core Ultra processors (Series 2), which ASUS lists as supported. A processor and motherboard must share the same socket, so this board is for those newer chips only and won't take processors from older generations. Check ASUS's CPU support list for specific models and any BIOS update requirement.

Micro-ATX size

Micro-ATX is smaller than a full ATX board. The listing gives 10.8 x 10.4 x 2.1 inches (about 27 x 26 x 5 cm) for the item. These boards fit in micro-ATX cases and most ATX cases, and they are common in compact builds. The trade-off is typically fewer expansion slots than an ATX board.

DDR5 memory

The board uses DDR5, the current generation of desktop memory, which offers higher bandwidth than DDR4. DDR5 and DDR4 modules are not interchangeable, so make sure you buy DDR5. Check the manual for how many slots there are and the supported speeds and capacity.

PCIe 4.0 and storage

ASUS describes a PCIe 4.0 x16 SafeSlot Core+ for the graphics card, a reinforced slot designed to resist the weight of heavy cards. There are two M.2 slots, both PCIe 4.0. PCIe 4.0 NVMe SSDs are typically several times faster than SATA drives, and are more than adequate for everyday work, games and large file transfers.

Power design

ASUS lists a 6+1+1+1 discrete MOS power design, a 4-layer PCB, 8-pin power connectors and durable capacitors, all aimed at stable power delivery to the processor. These figures matter most when you are pairing the board with higher-power processors. In general, a modest processor will be comfortable on a modest design.

Connectivity and ports

The listing mentions Intel 1Gb Ethernet and Wi-Fi 6, so you can connect by cable or wirelessly. For display output, there are DisplayPort and HDMI ports, which use the processor's integrated graphics if you don't add a graphics card. USB covers rear USB 10Gbps Type-A ports, plus a front-panel connector for USB 5Gbps Type-C.

The CSM line and "AI PC" claims

ASUS describes the Corporate Stable Model (CSM) as a commercial program intended to provide stable, reliable motherboards, which suits business and long-lifecycle use. It also says the board is ready for advanced AI PCs, with the power and connectivity for demanding AI applications. How much that matters depends on the processor you pair it with.

Who it suits

It suits builders of compact home, office and general-use PCs, and organisations that want a consistent platform. Those wanting many expansion cards or lots of storage may prefer a bigger board.

What to check before you buy

• Processor: confirm it is an LGA 1851 Core Ultra (Series 2) model, and check the BIOS requirements.
• Case: make sure it supports micro-ATX.
• Memory: buy DDR5 and check the supported speeds.
• Storage: count the M.2 and SATA connections you need.
• Cooler: check compatibility with the socket.
• Power supply: the board needs 8-pin CPU power, so check your PSU's connectors.
• Ports: make sure the rear and front connections cover your devices.
