ROG Strix B550-E Gaming

ASUS built ROG Strix B550-E Gaming with an eye towards AMD’s high-performance processors and dual or triple expansion card setups. The AM4 socket is flanked by a 14+2 power stage VRM for reliable performance under sustained loads from many-core CPUs, while reinforced PCIe x16 SafeSlots support multi-GPU action in two-way SLI™ or three-way CrossFireX™ setups for gamers and creators alike.

Strix B550-E Gaming’s six fan headers and dedicated AiO and pump headers allow for setups as simple or intricate as a given build requires. Q-Fan software controls with automatic fan-speed detection and multiple presets make it easy to keep both temperatures and noise levels down. Dual M.2 slots can take in SSDs up to 110 mm long, both covered by heatsinks to prevent thermal throttling under intense I/O loads. Strix B550-E Gaming also features an Intel-powered 2.5 Gbps Ethernet and WiFi 6 controllers, Bluetooth 5.1 support is on tap for wireless headsets, phones and tablets.

USB connectivity is particularly plentiful on Strix B550-E: it includes three USB 3.2 Gen 2 connectors (one Type-C and two Type-A), along with a smattering of USB 3.2 Gen 1 and USB 2.0 ports. ASUS has included a USB 3.2 Gen 2 front-panel connector for the latest crop of cases.

The high-end SupremeFX S1220A audio chip comes with a handy companion in the form of a USB-C Audio port for auto-detection of the device signal type, so the port can be used for both Type-C audio devices and standard USB connectivity as needed. A total of four strip headers are available – two standard headers and two Gen 2 addressable hook-ups with individual LED control, reduced latency and automatic configuration support. All those diodes can be turned off with one click to give the board a stealthy black-ops look. Additional touches include BIOS FlashBack for updating firmware without a CPU and FlexKey reset button remapping.

ROG Strix B550-I Gaming

ROG Strix B550-I Gaming is designed for small builds with big ambitions. By design, Mini-ITX makes room for a single PCIe 4.0 x16 slot, but the compact form factor has other advantages. Strix B550-I Gaming can drive compatible DIMMs at speeds up to 5100 MHz and beyond by taking advantage of the shorter trace length between the memory slots and the CPU. The 8+2 power stage VRM is a fine fit for 3^rd gen Ryzen chips. Active cooling on the VRM and an eight-pin connector with our ProCool II design ensure that power delivery remains stable in the tight confines of Mini-ITX enclosures.

The preinstalled I/O panel is kitted out with USB 3.2 Gen 2 Type-C and Type-A ports, an Intel I225-V 2.5 Gbps Ethernet connector, and an Intel AX200 WiFi 6 and Bluetooth 5.1 adapter. Small machines are more likely to have fast external storage attached, so ASUS engineers added a front-panel USB 3.2 Gen 2 connector for the latest cases. The 3.5 mm connectors are all LED lit in unique colors to allow for easy identification when connecting analog speakers, headsets or microphones. There’s a companion noise-filtered USB-C Audio port for corresponding microphones and headsets, too.

ASUS TUF Gaming B550-Plus
