ASUS Prime A520M-K DDR4 AMD Motherboard

The ASUS Prime A520M-K is a Micro-ATX motherboard built on the AMD A520 chipset, designed for AMD AM4 socket processors including 3rd Generation AMD Ryzen and 3rd Generation AMD Ryzen with Radeon Graphics. It offers a practical, well-rounded feature set for daily-use desktop builds and DIY PC builders who want reliable performance without overcomplication. Memory support is generous for its class: two DIMM slots accommodate up to 64GB of unbuffered DDR4 RAM, with native speeds of 2133 through 3200 MHz and overclocked profiles reaching up to 4600 MHz (O.C.). Dual-channel memory architecture is supported, and ECC mode availability depends on the installed processor. For storage, the board provides one M.2 Socket 3 slot (M Key, Type 2242/2260/2280) capable of both PCIe 3.0 x4 and SATA modes, delivering transfer speeds up to 32 Gbps via the PCIe interface. Four SATA 6Gb/s ports with RAID 0, 1, and 10 support round out the storage options. Display outputs include one D-Sub and one HDMI 2.1 port (4K at 60Hz) for integrated graphics connectivity. The single PCIe 3.0 x16 slot accommodates a discrete graphics card, while two PCIe 3.0 x1 slots provide expansion flexibility. Audio is handled by the Realtek ALC887 codec, offering 7.1 surround sound, up to 24-bit/192kHz playback, and dedicated audio PCB layers with audio shielding for cleaner output. Networking is provided by a Realtek RTL8111H 1Gb Ethernet controller, complemented by ASUS LANGuard surge protection. USB connectivity totals twelve ports across the board: six rear-panel ports (4x USB 3.2 Gen 1 Type-A and 2x USB 2.0) and internal headers supporting six additional front-panel ports (2x USB 3.2 Gen 1 and 4x USB 2.0). The board carries ASUS 5X Protection III, which includes DIGI+ VRM digital power delivery, overvoltage protection, SafeSlot Core, LANGuard, and a stainless-steel back I/O panel. An aluminum heatsink supports thermal management, and Fan Xpert software enables per-header fan curve control referencing up to three thermal sensors.
