ASUS Prime X570-Pro/CSM DDR5 AMD Motherboard

The ASUS Prime X570-Pro/CSM is a full-size ATX motherboard built on the AMD X570 chipset, designed for the AM4 socket and compatible with 3rd and 2nd Generation AMD Ryzen processors, as well as 2nd and 1st Generation AMD Ryzen processors with Radeon Vega Graphics. Measuring 12.0 x 9.6 inches (30.5 x 24.4 cm), it fits standard ATX mid-tower and full-tower enclosures. At its core, the board features a 12+2 DrMOS power stage design paired with ProCool connectors, alloy chokes, and durable capacitors, ensuring stable and clean power delivery for high-core-count Ryzen CPUs. Memory support spans four DIMM slots accommodating up to 128 GB of DDR4 un-buffered RAM in dual-channel configuration, with native speeds up to DDR4-3200 and overclocked profiles reaching DDR4-4400 (O.C.) when using 3rd Gen Ryzen processors. ECC memory is supported depending on the installed CPU. Storage flexibility is a standout feature: two M.2 Socket 3 (M Key) slots support PCIe 4.0 x4 and SATA modes for drives in 2242, 2260, 2280, and 22110 form factors, complemented by six SATA 6Gb/s ports with RAID 0, 1, and 10 support. Expansion slots — governed by the installed CPU generation — include two PCIe 4.0 x16 slots (x16 or dual x8 with 3rd Gen Ryzen), plus chipset-driven PCIe 4.0 x1 and x16 (x4 mode) slots. Connectivity on the rear I/O includes four USB 3.2 Gen 1 Type-A ports, three USB 3.2 Gen 2 Type-A ports, one USB 3.2 Gen 2 Type-C port, a DisplayPort 1.2 output, an HDMI 2.0b output (both supporting up to 4096×2160 @ 60 Hz with compatible APUs), one Intel I211-AT Gigabit LAN port with ASUS LAN Guard protection, optical S/PDIF out, five audio jacks, and a PS/2 combo port. A USB 3.2 Gen 2 front-panel header extends high-speed connectivity to the chassis. Audio is handled by the Realtek S1220A 8-channel HD codec with Crystal Sound 3, delivering 120 dB SNR stereo playback and 113 dB SNR line-in recording. The audio subsystem uses dedicated PCB layers for channel separation, Japanese-made capacitors, and an EMI shield over the amplifier. The board is part of ASUS's Corporate Stable Model (CSM) program, which provides up to 36 months of product lifecycle support and a 6-month end-of-life notice — making it suitable for commercial and enterprise deployments. Each unit includes ASUS Control Center Express, a centralized IT management application for asset tracking, software deployment, and remote monitoring. Additional features include ASUS Aura Sync RGB lighting with two RGB strip headers and one Addressable Gen 2 header, Fan Xpert 4 with auto-tuning, 5-Way Optimization for one-click performance tuning, ASUS 5X Protection III (SafeSlot, LANGuard, overvoltage protection, ESD guards, and stainless-steel back I/O), and a pre-mounted I/O shield for easier builds. BIOS is a 256 Mb UEFI AMI implementation with CrashFree BIOS 3 and EZ Flash 3.
