This article covers Asustek Computer Prime A520M.

Overview

The ASUS Prime A520M-E is a microATX motherboard built on the AMD A520 chipset, designed for Socket AM4 processors. It supports 3rd Gen AMD Ryzen CPUs and features two DDR4 memory slots with support for up to 64GB of RAM. The board includes a single M.2 slot for NVMe SSDs, four SATA 6Gbps ports, and a range of legacy video outputs including HDMI, DVI, and D-Sub. With USB 3.2 Gen 2 Type-A connectivity and a 1Gb Ethernet port, it covers the essentials for a budget-oriented builder's essential needs. Positioned as an entry-level motherboard, the Prime A520M-E offers a solid foundation for cost-effective PC builds.

Compatibility Guide

The Prime A520M-E uses the AM4 socket, compatible with Ryzen 3000 series (Matisse) and 4000 series APUs (Renoir). Memory support includes DDR4-3200 (OC) via two DIMM slots for dual-channel operation. The microATX form factor (244mm x 244mm) fits in most ATX and microATX cases. Expansion includes one PCIe 3.0 x16 slot and two PCIe 3.0 x1 slots. Storage connectivity comprises four SATA 6Gbps ports and one M.2 slot (PCIe 3.0 x4 slot. Power is supplied via a 24-pin ATX main connector and an 8-pin CPU power connector. Note that the A520 chipset does not support CPU overclocking, but memory overclocking (XMP) is available.

Product Info

Released in 2020, the Prime A520M-E remains a current entry-level offering from ASUS. Its typical street price is around ¥19,000, making it an attractive option for budget-conscious builders. The motherboard carries a standard three-year warranty. It is widely available through major retailers and online stores. The A520 chipset limits PCIe to 3.0, which is sufficient for most mainstream graphics cards and SSDs. The board's VRM design is modest, best paired with CPUs up to 65W TDP (e.g., Ryzen 5 3600) for reliable operation.

Best Use Cases

Budget Gaming Build: Pair the Prime A520M-E with a Ryzen 3 3100 or Ryzen 5 3600 and a mid-range GPU like the GTX 1660 Super for a capable 1080p gaming rig without breaking the bank. Office & Home PC: Use a Ryzen 5 3400G APU to leverage integrated graphics for everyday tasks, web browsing, and media consumption. The multiple video outputs allow dual-monitor setups. * Compact Server or HTPC: The microATX size fits in small cases, and the four SATA ports provide ample storage for a file server or home theater PC.

Things to Consider

The lack of PCIe 4.0 support means you won't get the full speed from the latest GPUs or NVMe SSDs. CPU overclocking is not supported, so enthusiasts should look at B550 or X570 boards. The two DIMM slots limit future memory expansion; plan your RAM capacity upfront. The VRM is basic, so avoid high-TDP CPUs like the Ryzen 9 3900X for sustained workloads. Additionally, there is no onboard Wi-Fi or Bluetooth, requiring a separate adapter for wireless connectivity. ## Specifications | Item | Specification | |------|---------------| | Chipset | AMD A520 | | CPU Socket | Socket AM4 | | Form Factor | microATX (244mm x 244mm) | | Memory Slots | 2 x DIMM (DDR4) | | Max Memory | 64GB (32GB per DIMM) | | Memory Speed | DDR4-3200 (OC) | | Expansion Slots | 1 x PCIe 3.0 x16, 2 x PCIe 3.0 x1 | | M.2 Slot | 1 x M.2 (PCIe 3.0 x4 & SATA) | | SATA Ports | 4 x SATA 6Gbps | | USB Ports | 2 x USB 3.2 Gen 2 Type-A (rear), 4 x USB 3.2 Gen 1 (internal), 6 x USB 2.0 (internal) | | Video Output | HDMI 1.4b, DVI-D, D-Sub | | LAN | Realtek RTL8111H 1Gb Ethernet | | Audio | Realtek887 7.1ch HD Audio | | Power Connectors | 24-pin ATX 24-pin, CPU 8-pin | | Supported OS | Windows 10 64-bit | | Warranty | 3 years |
