Socket AM4 Micro-ATX foundation
The ASUS TUF GAMING B450M-PRO S is a Micro-ATX motherboard built around the AMD B450 chipset and the AM4 socket. It accepts 1st, 2nd and 3rd Generation Ryzen processors as well as Athlon models with Radeon Vega graphics. Four 288-pin DDR4 slots support up to 128 GB in dual-channel mode with speeds ranging from 2133 to 4400 MHz when overclocked.
Builders who need compact expandability
This board suits system builders who want a smaller chassis without losing four memory slots, two full-length PCI Express slots and three M.2 sockets. Users planning heavy multi-GPU arrays or workstation-class I/O should look at full-size ATX or TRX40 platforms instead.
8+2 DrMOS power stages for sustained loads
The 8+2 DrMOS power-stage design delivers clean current to the CPU, making it the specification that determines whether the board can handle sustained all-core loads on higher-TDP Ryzen chips without throttling.

Questions sur cet article
What is included with the ASUS TUF GAMING B450M-PRO S motherboard and what must be purchased separately?
The motherboard includes the board itself, I/O shield, SATA cables, M.2 screws and driver disc. You must buy a compatible AM4 processor, DDR4 memory modules, storage drives, graphics card if the CPU lacks integrated graphics, power supply, case and CPU cooler separately.
Which DDR4 memory speed should I choose for this board — 3200 MHz or a higher overclocked rating like 4400 MHz?
The board runs DDR4 at 2666 MHz natively. Speeds from 2800 MHz up to 4400 MHz are overclock profiles that require XMP/DOCP support on the memory kit and a capable Ryzen CPU memory controller; 3200 MHz is a common sweet spot for stability and performance.
What does the 2.5 Gb LAN figure mean for actual network throughput on this motherboard?
The 2.5 Gb LAN controller provides up to 2.5 gigabits per second wired bandwidth, roughly 2.5 times standard gigabit Ethernet. Real-world throughput depends on your router, switch, cabling (Cat 5e or better) and internet plan, but local file transfers can approach 280 MB/s.
