Overview
The ASUS Prime A520M-K is a Micro-ATX form-factor motherboard built on AMD's A520 chipset and designed for the AM4 socket. It provides a reliable platform for DIY PC builders looking to pair an entry-level board with AMD Ryzen desktop processors without sacrificing essential connectivity or stability. Processor compatibility spans AMD Ryzen 5000 Series, Ryzen 5000 G-Series, Ryzen 4000 G-Series, Ryzen 3000 Series, and Ryzen 3000 G-Series desktop processors — making this board a practical choice for a wide range of current-generation AMD CPUs available in India. Memory support uses the DDR4 standard in dual-channel configuration, with a maximum capacity of 64 GB and support for speeds up to 5100 MHz (OC). Two DIMM slots accommodate these modules, letting you start with a single stick and expand later. Storage and expansion options include one M.2 Socket 3 (M-key) slot that accepts 2242, 2260, and 2280 form-factor drives in both SATA and PCIe 3.0 x4 modes, as well as four SATA 6 Gb/s ports for traditional drives. The PCIe expansion layout features one PCIe 3.0 x16 slot running in x16 mode and two PCIe 3.0 x1 slots. Display output is handled by one HDMI port and one D-Sub (VGA) port on the rear panel, catering to builds that rely on AMD's integrated graphics. Connectivity on the rear I/O panel includes four USB 3.2 Gen 1 Type-A ports, two USB 2.0 ports, one PS/2 keyboard/mouse combo port, one RJ-45 Gigabit Ethernet port, and three 3.5 mm audio jacks. Internal headers add two USB 3.2 Gen 1 headers (supporting two additional ports) and two USB 2.0 headers (supporting four additional ports), plus a front-panel audio connector, S/PDIF out header, and SPI TPM header. Cooling is supported by a PCH heatsink, one CPU fan header, and one chassis fan header, with configuration available through ASUS Fan Xpert software or the UEFI BIOS. ASUS's 5X Protection III hardware safeguards are included for component-level protection. The board carries a 3-year manufacturer warranty. — Verified Specifications — Socket: AM4 | Chipset: AMD A520 | Form Factor: Micro-ATX | Memory: DDR4 Dual-Channel, up to 64 GB, up to 5100 MHz (OC) | Storage: 1× M.2 (PCIe 3.0 x4 / SATA), 4× SATA 6 Gb/s | Display: 1× HDMI, 1× D-Sub | USB (Rear): 4× USB 3.2 Gen 1 Type-A, 2× USB 2.0 | LAN: 1× Gigabit Ethernet | PCIe: 1× x16 (x16), 2× x1 | Warranty: 3 Years
