ASUS TUF Gaming B450M Pro II DDR4 AMD Motherboard

The ASUS TUF Gaming B450M Pro II is a Micro-ATX motherboard built on the AMD B450 chipset, designed for the AM4 socket. It is compatible with AMD Ryzen 5000 Series, 5000 G-Series, 4000 G-Series, and 1st through 3rd generation Ryzen processors, as well as AMD Athlon processors with Radeon Vega Graphics, giving builders considerable CPU flexibility within a compact 9.6 x 9.6 inch (24.4 x 24.4 cm) footprint. Memory support is generous for the platform: four DDR4 DIMM slots accommodate up to 128 GB of unbuffered RAM in dual-channel configuration, with native speeds of 2133/2400/2666 MHz and overclocked profiles reaching up to 4400 MHz (O.C.), subject to processor capability. ECC memory is supported in ECC mode on compatible CPUs. Storage options are well-rounded. Two M.2 slots accept 2242/2260/2280 form-factor drives — the primary slot runs at PCIe 3.0 x4 or SATA with Ryzen CPUs, while the secondary chipset-connected slot operates at PCIe 3.0 x2 or SATA. Six SATA 6 Gb/s ports round out the storage complement, all supporting RAID 0, 1, and 10. Connectivity on the rear I/O panel includes two USB 3.2 Gen 2 ports (one Type-A, one Type-C), four USB 3.2 Gen 1 Type-A ports, two USB 2.0 ports, DisplayPort 1.2, HDMI 2.0b, a Gigabit Ethernet port backed by the Realtek RTL8111H controller with TUF LANGuard surge protection, and three audio jacks. A BIOS FlashBack button enables firmware updates without a CPU or RAM installed. Audio is handled by the Realtek ALC S1200A codec, delivering 7.1 surround sound with up to 108 dB signal-to-noise ratio on stereo line out and 103 dB SNR on line in, alongside dedicated audio PCB layers, audio shielding, and premium Japanese audio capacitors. DTS Custom for gaming headsets is included in the software bundle. ASUS Armoury Crate software provides centralized control of Aura Sync RGB lighting, fan curves via Fan Xpert 2+, and system tuning. Two onboard AURA RGB strip headers let you extend lighting to compatible accessories. The AI Noise-Canceling Microphone feature, accessible through Armoury Crate, improves in-game voice clarity. Protection features include DIGI+ VRM digital power delivery, ESD Guards on USB and LAN ports, Enhanced DRAM Overcurrent Protection, Overvoltage Protection, SafeSlot reinforced PCIe x16 slot, and a stainless-steel back I/O panel. The board ships with a 3-year manufacturer warranty.
