ASUS TUF Gaming B450-Plus II DDR4 AMD Motherboard

The ASUS TUF Gaming B450-Plus II is an ATX form factor motherboard built on the AMD B450 chipset with an AM4 socket, supporting AMD Ryzen 5000 Series, 5000 G-Series, 4000 G-Series, third, second, and first-generation Ryzen processors, as well as Ryzen with Radeon Vega Graphics and Athlon with Radeon Vega Graphics CPUs. Designed for builders who prioritise stability and longevity, the board features an 8+2 DrMOS power stage configuration. DrMOS integrates the high-side MOSFET, low-side MOSFET, and driver into a single package, improving power efficiency and thermal management for high-core-count Ryzen processors. Memory support extends to four DIMM slots accommodating up to 128 GB of unbuffered DDR4 in dual-channel configuration, with native speeds of 2133/2400/2666 MHz and overclocked profiles reaching up to DDR4-4400 (O.C.). Storage is handled by two M.2 Socket 3 slots — the first (CPU-side) supports SATA and PCIe 3.0 x4 devices in 2242/2260/2280/22110 form factors, while the second (chipset-side) supports PCIe 2.0 x4 devices up to 2280 — plus six SATA 6 Gb/s ports with RAID 0, 1, and 10 support. Connectivity on the rear I/O panel includes two USB 3.2 Gen 2 ports (one Type-C, one Type-A), four USB 3.2 Gen 1 Type-A ports, two USB 2.0 ports, DisplayPort 1.2, HDMI 2.0b, a Gigabit LAN port via the Realtek L8200A controller with TUF LANGuard surge protection, five audio jacks, and a BIOS FlashBack button for CPU-free firmware updates. Audio is delivered by the Realtek ALC S1200A 8-channel HD codec with a 108 dB signal-to-noise ratio for stereo line output and 103 dB SNR for line input. Audio shielding, dedicated PCB layers for left and right channels, and Japanese-made capacitors contribute to audio signal integrity. DTS Custom for gaming headsets is included in the software bundle. Thermal management is supported by VRM heatsinks, a PCH heatsink, and Fan Xpert 4 Core with four fan/pump headers (one CPU, three chassis, one AIO pump). RGB aesthetics are handled through Aura Sync with two onboard Aura RGB strip headers. Protection features include SafeSlot reinforced PCIe x16, overvoltage protection, ESD guards, and stainless-steel back I/O.
