ASUS ROG Strix B850-A Gaming WiFi

A striking white-PCB ATX motherboard for AMD Ryzen 9000 — 14+2+2 80A VRM, PCIe 5.0 GPU and Gen5 M.2, Wi-Fi 7 and SupremeFX audio.
AMD B850 · AM5 · White Wi-Fi 7 + 2.5GbE PCIe 5.0 + Gen5 M.2 USB 20Gbps Type-C

The ASUS ROG Strix B850-A Gaming WiFi is an ATX motherboard for AMD Ryzen 9000, 8000 and 7000 series desktop processors on Socket AM5, designed around a striking white PCB with matching metallic heatsinks for clean modern builds. It pairs a 14+2+2 stage 80A VRM with ProCool 8+8-pin CPU power, four DDR5 DIMM slots up to 256 GB with EXPO and AEMP support, one PCIe 5.0 x16 SafeSlot for the latest GPUs, and four M.2 slots — one PCIe 5.0 x4 plus three PCIe 4.0 x4, all with substantial heatsinks. Networking covers 2x2 Wi-Fi 7 (802.11be) with Bluetooth 5.4 and Intel 2.5 GbE LAN, plus a rear USB 20 Gbps Type-C port and ROG SupremeFX ALC4080 audio with Savitech amplifier and Dolby Atmos.

Compatibility Note: ATX form factor — confirm your case supports ATX. AM5 socket — only AMD Ryzen 9000 / 8000 / 7000 series desktop CPUs are supported. The M.2_3 slot shares bandwidth with the secondary PCIEX16(G4) slot — when that PCIe slot is in use, M.2_3 is disabled.

Frequently Asked Questions

Which CPUs does this motherboard support?
AMD Ryzen 9000, 8000 and 7000 series desktop processors on Socket AM5. PCIe 5.0 x16 mode and PCIe 5.0 x4 M.2 are enabled with Ryzen 9000 / 7000; Ryzen 8000 series operate at PCIe 4.0. A BIOS update may be needed for the very latest Ryzen 9000 SKUs.
Is the white finish just the PCB or the heatsinks too?
Both. The board uses a white PCB with matching silver-white metallic heatsinks and an integrated I/O shroud, designed to coordinate with white cases, GPUs and air or AIO coolers.
Can I use all four M.2 slots simultaneously?
Yes for normal use, with one caveat: the M.2_3 slot shares bandwidth with the secondary PCIEX16(G4) slot. If you populate that PCIe slot with a card, M.2_3 will be disabled.
What's included in the box?
Motherboard, 2× SATA 6Gb/s cables, ASUS WiFi Q-Antenna, M.2 Q-Latch and Q-Slide packages, 4× M.2 rubbers, ROG keychain and stickers, cable ties and quick start guide. CPU, RAM, SSD and OS are not included.
Singular Expert Insight
Choose this board if you want a ROG-tier ATX AM5 platform in a clean white aesthetic — the 14+2+2 80A VRM is one of the strongest in the B850 class, easily handling Ryzen 9 X3D chips, and you get four M.2 slots with PCIe 5.0, Wi-Fi 7 and a USB 20Gbps Type-C port. If you don't need the white look or care about the strongest VRM at this tier, the ROG Strix B850-F Gaming WiFi (black) is the closest sibling. If you want USB4 / Thunderbolt and stronger 16+2+2 power, step up to the ROG Strix X870-A or X870E. For a more affordable AM5 path without ROG branding, the ASUS TUF Gaming B850-PLUS WIFI is worth a look.

Buyer's Guide

Buy it if
You're building a white-themed AM5 ATX gaming rig with Ryzen 7000 / 9000, want PCIe 5.0 GPU and Gen5 NVMe, ROG-tier audio, Wi-Fi 7 and a serious 14+2+2 80A VRM that can comfortably handle Ryzen 9 X3D chips.
Skip it if
You need USB4 / Thunderbolt, 5GbE LAN, two PCIe 5.0 x16 slots, or you prefer a black/dark aesthetic — the white finish defines this board's intent.
Also consider
ASUS ROG Strix B850-F Gaming WiFi (black equivalent with 16+2+2 stages), or step up to the ROG Strix X870-A WIFI for USB4 and a higher-tier feature set.
