ASUS ROG Strix B550-F Gaming AMD motherboard A

AM4 B550 platform for Ryzen CPUs

This ATX motherboard uses the AMD B550 chipset and an AM4 socket to support a wide range of Ryzen desktop processors. It provides four DDR4 memory slots with a maximum capacity of 128GB for high-throughput workloads. A single PCI Express 3.0 x16 slot and one legacy PCI slot handle graphics and expansion cards.

Sustained load behaviour with VRM cooling

The board’s power delivery is designed to maintain stable voltage during extended multi-core workloads such as rendering or compiling. Heatsinks on the VRM area and the chipset dissipate heat without relying on active cooling, so performance remains consistent over long sessions. Manufacturer refurbishment includes full functional testing under load.

PCIe 3.0 x16 and SATA interface limits

The primary graphics slot operates at PCI Express 3.0 x16 bandwidth, which caps throughput for modern GPUs that support higher link speeds. Storage devices connect through SATA ports limited to 6Gbps, so sequential transfers cannot exceed that ceiling. The rear I/O includes one USB 3.1 Gen 2 Type-A port, one DisplayPort and a single RJ45 LAN connection.
