ASUS ROG Strix B550-E Gaming Wifi DDR4 AMD Motherboard

The ASUS ROG Strix B550-E Gaming WiFi is a full-size ATX motherboard (30.5 cm × 24.4 cm) built around the AMD B550 chipset for AMD AM4 socket processors, with verified support for 3rd Gen AMD Ryzen CPUs. It is designed to deliver a high-end feature set at the B550 tier, anchored by a 14+2 teamed power stage design that combines high-side and low-side MOSFETs into single packages, paired with ASUS DIGI+ digital VRM control, a ProCool reinforced power connector, alloy chokes, and a 6-layer PCB for efficient heat dissipation. Memory support spans four DIMM slots accepting up to 128 GB of unbuffered DDR4 in dual-channel configuration, with native speeds up to DDR4-3200 and overclocked profiles reaching DDR4-4400 via XMP or DOCP. OptiMem II trace routing and optional ECC support (CPU-dependent) round out memory flexibility. Storage is handled by two M.2 slots — the primary M.2_1 runs at PCIe 4.0 x4 from the CPU, while M.2_2 runs PCIe 3.0 x4 from the B550 chipset — alongside six SATA 6 Gb/s ports with RAID 0, 1, and 10 support. Both M.2 slots accommodate 2242, 2260, 2280, and 22110 form factors and include an aluminum heatsink for thermal management. Expansion slots include two PCIe 4.0 x16 slots (running x16 or dual x8 mode) sourced from the CPU, one PCIe 3.0 x16 slot in x4 mode from the chipset, and two PCIe 3.0 x1 slots. Multi-GPU configurations are supported: NVIDIA 2-Way SLI and AMD 3-Way CrossFireX. Networking is handled by an Intel I225-V 2.5 Gb Ethernet controller with ASUS LANGuard protection, complemented by an Intel Wi-Fi 6 AX200 module delivering 802.11ax (2.4/5 GHz, HT20/HT40/HT80/HT160, 1024-QAM, OFDMA, MU-MIMO) and Bluetooth 5.1. Audio is provided by the ROG SupremeFX S1220A codec — a 7.1-channel high-definition implementation featuring dual op-amplifiers, impedance sensing for front and rear headphone outputs, 120 dB SNR stereo playback, 113 dB SNR recording input, and support for up to 32-bit/192 kHz playback (note: 32-bit/192 kHz is not available at 7.1-channel due to HDA bandwidth limits). Premium Japanese audio capacitors, SupremeFX Shielding technology, and a dedicated rear audio USB Type-C port complete the audio section. The rear I/O panel provides 3 × USB 3.2 Gen 2 ports (2 × Type-A, 1 × Type-C), 5 × USB 2.0 ports (including 1 dedicated audio USB Type-C), DisplayPort 1.2, HDMI 2.1 (4K@60 Hz), 5 audio jacks, and a BIOS FlashBack button for CPU-free firmware updates. Internal headers support an additional 7 front-panel USB ports across Gen 2, Gen 1, and USB 2.0 connectors, plus a Thunderbolt header, AIO pump connector, and 5 fan/pump headers. Aura Sync RGB is integrated with two standard RGB headers and two Addressable Gen 2 headers. Q-Design features include Q-CODE diagnostic display, Q-DIMM, Q-LED indicators, Q-Slot, and a pre-mounted I/O shield. SafeSlot reinforces the primary PCIe x16 slot. Software includes AI Suite 3 with 5-Way Optimization, Fan Xpert 4, Armoury Crate, Aura Creator, Sonic Studio III, Sonic Radar III, GameFirst VI, RAMCache III, and DTS Sound Unbound. BIOS is UEFI AMI with 256 Mb Flash ROM. Backed by a 3-year warranty.
