ASUS ROG Strix X870-A Gaming Wifi DDR5 AMD Motherboard

The ASUS ROG Strix X870-A Gaming WiFi is a full-size ATX motherboard built on the AMD X870 chipset, designed for AMD Socket AM5 processors including Ryzen 9000, 8000, and 7000 Series desktop CPUs. Finished with a distinctive white PCB, it fits cleanly into white or neutral builds while delivering a feature set aimed at enthusiast gamers and power users. Memory support spans four DDR5 DIMM slots with a combined maximum capacity of 192 GB. The board accommodates speeds up to 8000+ MT/s (OC) with compatible Ryzen 9000, 8000, and 7000 Series processors, and supports both AMD EXPO and ASUS AEMP profiles for straightforward memory overclocking. The dual-channel architecture makes the most of modern DDR5 bandwidth. Storage options are generous: two PCIe 5.0 x4 M.2 slots (M.2_1 and M.2_2) deliver next-generation NVMe throughput, while two further PCIe 4.0 x4 M.2 slots (M.2_3 and M.2_4) via the X870 chipset round out the total to four M.2 slots. Two SATA 6 Gb/s ports serve legacy drives. Connectivity is a clear highlight. The rear panel provides two USB4 (40 Gbps) Type-C ports with DisplayPort Alt mode, six USB 10 Gbps ports (five Type-A plus one Type-C with up to 30 W Power Delivery fast-charge), and four USB 5 Gbps Type-A ports. Internal headers add a USB 20 Gbps Type-C connector plus headers for four additional USB 5 Gbps and four USB 2.0 ports. Wired networking is handled by Intel 2.5 Gb Ethernet with ASUS LANGuard protection, while wireless uses a 2×2 Wi-Fi 7 (802.11be) adapter covering 2.4 GHz, 5 GHz, and 6 GHz bands, paired with Bluetooth 5.4. Display outputs on the rear I/O include one DisplayPort (max 8K@30Hz per DisplayPort 1.4) and one HDMI port, supplemented by the two USB4 ports that also carry DisplayPort Alt mode. Audio is managed by the ROG SupremeFX codec using a Realtek ALC4080, supporting 7.1 surround sound with 32-bit/384 kHz playback, impedance sense, and jack detection. Overclocking tools include the Dynamic OC Switcher, which automatically transitions between manual overclock and Precision Boost Overdrive profiles based on user-defined current and temperature thresholds. Core Flex allows granular control over clock, power, and thermal limits, and the board features a built-in clock generator to isolate CPU base clock from memory, PCIe, and Infinity Fabric domains. The BIOS uses a 256 Mb Flash ROM with UEFI AMI firmware. Fan and cooling headers include one 4-pin CPU Fan, one 4-pin CPU OPT, one 4-pin AIO Pump, and five 4-pin chassis fan headers. Power delivery uses a 24-pin main connector plus two 8-pin +12 V CPU connectors. Aura Sync ARGB lighting is supported for ecosystem-wide RGB control.
