The high-end ASUS ROG Strix B850A Gaming Wi-Fi motherboard is made for enthusiasts who want to assemble a robust and aesthetically pleasing Ryzen system. Its design, featuring a white motif and black and silver accents, creates a dramatic look that complements contemporary construction.

By turning the PCB itself white, ASUS has gone one step further and achieved a smooth contrast with the integrated components and silver heat sinks.

Design of the Board

Due to its thoughtful design, the motherboard is both aesthetically pleasing and well-suited for high-performance systems. The combination of silver heat sinks, white accents, and a few black highlights makes it one of the best-looking B850 motherboards available.

The top heat sinks cover critical components, including the power delivery system, while maintaining a clean and stylish appearance.

CPU Socket and VRM

At the heart of the board is AMD's AM5 socket, supporting Ryzen 9000, 8000, and 7000 series processors. Surrounding the CPU socket, ASUS has implemented a 14+2+2 power phase design with 80A power stages and high-quality alloy chokes.

Two silver heat sinks cover the power delivery components, with the rear IO cover partially overlapping one of the heat sinks. This all-white cover, featuring the ROG logo, contrasts nicely with the silver heat sinks, enriching the overall aesthetics.

Top-Edge of the Board

There are two eight-pin EPS connectors in the upper corner. Installing both guarantees more reliable power delivery for high-end processors and overclocking, even though only one is required for everyday use.

Three four-pin fan headers are provided across the top: an optional CPU fan header, an AIO pump header, and a CPU fan header. If these headers are not being used, ASUS provides protective covers to keep them looking neat and tidy.

Slots for DDR5

The motherboard's DDR5 DIMM slots support up to 256 GB of DDR5 8000 memory. The slots' notable lack of bottom-side locks makes it simpler to install and upgrade RAM, even when a large graphics card is mounted.

Front-Edge Connections

Along the front edge, users will find a three-pin addressable RGB header, a power button, a 24-pin ATX power connection, a USB 3.2 Gen2 header, and a USB 3.2 Gen1 header. Two SATA 6Gb/s ports are positioned at a 90° angle to prevent interference with expansion cards.

Bottom Connections

The bottom half of the motherboard houses additional headers, including front panel audio, two four-pin fan headers, two three-pin addressable RGB headers, a Thunderbolt header, two USB 2.0 headers, and front panel headers. Heat sinks occupy much of the bottom half, featuring multiple ROG and Strix logos.

Designed for PCIe 5.0 NVMe SSDs, the top heat sink features the M.2 Q release system for simple screw-free installation and removal.

M.2 Slots

The remaining M.2 slots function at PCIe 4.0, but removing the top heat sink reveals a PCIe 5.0 slot. The M.2 Q latch system is used in all slots, simplifying and eliminating the need for tools during drive installation. The M.2 drive is locked in place when the latch is pressed down, and it is released when it is lifted. Upgrading and maintaining M.2 is made easier using this system.

Slots for expansion

The motherboard comes with two PCIe x16 slots: a metal-reinforced PCIe 5.0 slot at the top and a PCIe 4.0 slot at the bottom, both with X4 electrical connectivity.

Instead of a traditional release button, ASUS provides the PCIe Slot Q Release Slim system, allowing users to remove graphics cards easily by lifting in a specific direction. The system works flawlessly and eliminates the need for levers or buttons.

Rear I/O

The integrated rear IO shield is white, matching the board. It includes DisplayPort, HDMI, four USB 3.2 Gen 1 ports, three USB 3.2 Gen 2 ports (including Type-C), two USB 2.0 ports, a clear CMOS button, a BIOS Flashback button, 2.5Gb LAN, Wi-Fi 7 connectors, and audio connections. The Wi-Fi 7 antennas are white and feature simple press-in Q connectors for easy installation and removal.

RGB Lighting

RGB lighting is minimal, limited to the ROG logo on the rear IO cover. Additional lighting can be added using the three onboard RGB headers for system customization.

Final Thoughts

ASUS ROG Strix B850A Gaming Wi-Fi motherboard is feature-rich, offering Zen 5 support on the top PCIe slot and top M.2 slot. With four M.2 slots, it can accommodate storage-heavy builds with ease. Building and upgrading are made easy by the M.2's unique graphics card release system and tool-free installation.

Wi-Fi 7 and USB 3.2 Gen 2 support are among the connectivity options, and the antenna positioning is thoughtfully planned for a simple setup. The board looks great for builds with a white theme.

It offers great pricing for Ryzen builds, even though it lacks some of the more sophisticated capabilities available on X870 or X870E boards, like more reliable VRMs, USB4, or Thunderbolt 4. This motherboard is highly recommended for most customers due to its overall good performance, ease of use, and stylish design.
