ASRock A520M Pro4 AMD motherboard

Socket AM4 Platform

The ASRock A520M Pro4 is an AMD motherboard built for Ryzen 3000, 4000 G-Series, 5000 and 5000 G-Series desktop processors. It uses an 8-phase digital power design with 50A high-efficiency inductors and a 2 oz copper PCB. The board targets builders who want a reliable foundation for mainstream computing and gaming without overclocking headroom.

Build Integration

Two PCIe 3.0 x16 slots and a dedicated M.2 Key E connector provide expansion for graphics and wireless cards. Four SATA3 ports and two M.2 sockets — one PCIe Gen3 x4, the other PCIe Gen3 x2 and SATA3 — handle storage. Ten USB 3.2 Gen1 ports (five rear, one rear C-type, four front) cover peripheral connectivity. HDMI, DisplayPort and D-Sub outputs support integrated graphics on G-Series CPUs. Buyers who need more storage lanes or a second full-length graphics card should look elsewhere.

Capacity And Headroom

Four DDR4 slots run dual-channel memory up to DDR4 4733+ (OC) with Vermeer and Matisse processors, covering speeds from 2133 through 4733. The Super M.2 slot delivers PCIe Gen3 x4 bandwidth for a primary drive. Realtek ALC1200 codec with Nahimic Audio provides 7.1-channel output. The A520 chipset limits PCIe to Gen3 and offers no CPU overclocking, so enthusiasts seeking Gen4 storage or unlocked multiplier control will hit a ceiling.
