ASUS TUF B450M Pro Gaming DDR4 AMD Motherboard

The ASUS TUF B450M Pro Gaming is a Micro-ATX motherboard built around the AMD B450 chipset, designed for AMD AM4-socket processors including Ryzen 2nd Generation, Ryzen 1st Generation, Ryzen with Radeon Vega Graphics, and Athlon with Radeon Vega Graphics. Measuring 9.6 x 9.6 inches (24.4 x 24.4 cm), it fits compact mid-tower and small form-factor cases while delivering a feature set suited to extended gaming sessions. Memory support spans four DIMM slots accommodating up to 64 GB of unbuffered DDR4 in dual-channel configuration. Native speeds run at 2133, 2400, and 2666 MHz, with overclocked profiles reaching up to DDR4-3533 depending on the installed CPU. Storage flexibility is a strong point. Two M.2 Socket 3 slots (M-key, supporting 2242/2260/2280 form factors) are present: one connected to the CPU lanes supporting both SATA and PCIe 3.0 x4 mode (with Ryzen processors), and one from the B450 chipset supporting SATA and PCIe 3.0 x2. Six SATA 6 Gb/s ports round out the storage complement, with RAID 0, 1, and 10 support. Audio is handled by the Realtek ALC S1200A 8-channel HD codec, which achieves a 108 dB signal-to-noise ratio on the stereo line-out and 103 dB SNR on the line-in. Dedicated audio PCB layers, audio shielding, and Japanese-made audio capacitors contribute to signal clarity. Exclusive DTS Custom software delivers positional audio presets — Aerial, Soundscape, and Tactical — via stereo headphones. Connectivity at the rear I/O includes one USB 3.1 Gen 2 Type-A, one USB 3.1 Gen 1 Type-C, two USB 3.1 Gen 1 Type-A, two USB 2.0 ports, HDMI 2.0b (up to 4096×2160 @ 60 Hz), DVI-D, Gigabit LAN via Realtek RTL8111H with TUF LANGuard surge protection, a PS/2 combo port, and three audio jacks. Internally, a 19-pin USB 3.1 Gen 1 header and two USB 2.0 headers add further expansion. The TUF Protection suite encompasses SafeSlot PCIe reinforcement, DDR4 overvoltage protection, DIGI VRM for precise power delivery, stainless-steel back I/O shielding, and ESD guards. Fan Xpert 2+ provides granular thermal control via one 4-pin CPU fan header and two 4-pin chassis fan headers, including GPU temperature sensing for ASUS graphics cards. Two Aura Sync RGB strip headers allow lighting coordination with compatible peripherals. The UEFI AMI BIOS (128 Mb Flash ROM) supports ACPI 6.1, SM BIOS 3.1, CrashFree BIOS 3, EZ Flash 3, and multilanguage operation. AMD StoreMI storage-acceleration technology is supported on compatible Ryzen platforms.
