Pros & Cons
Pros
- ✓ One NVMe PCIe 3.0 x4 M.2 slot on board, no add-in card needed for a boot SSD
- ✓ Three rear display outputs (D-Sub, DVI, HDMI) for Ryzen APU and legacy-monitor builds
- ✓ 4+3 phase digital PWM power delivery on a MicroATX board
- ✓ Q-Flash Plus BIOS updating, 1GbE LAN and RGB Fusion 2.0 lighting control
Cons
- ✗ Only two DDR4 DIMM slots, so memory upgrades mean replacing sticks
- ✗ PCIe 3.0 throughout, no PCIe 4.0 lanes for newer GPUs or SSDs
- ✗ Single M.2 slot; a second NVMe drive needs a PCIe adapter
- ✗ ALC887 is an entry-level audio codec, not a higher-tier Realtek part
Manufacturer description
The Gigabyte A520M S2H is a MicroATX motherboard built for AM4 systems that need current features without paying for overclocking headroom. It supports 3rd Gen AMD Ryzen processors on the AMD AM4 socket, pairs them with dual-channel DDR4 across two DIMM slots, and feeds the CPU through a 4+3 phase digital PWM design that keeps power delivery orderly for mainstream Ryzen chips. Storage and expansion cover the essentials. One NVMe PCIe 3.0 x4 M.2 slot takes a boot drive with no SATA cabling and no add-in card, while a PCIe 3.0 x16 slot handles your graphics card. Three rear display interfaces…

Frequently Asked Questions
Which CPUs does the Gigabyte A520M S2H support?
It uses the AMD AM4 socket and supports 3rd Gen AMD Ryzen processors. Confirm your exact CPU model against Gigabyte's official support list before buying, since support can depend on the installed BIOS version.
How much RAM can I install in the A520M S2H?
The board has two DIMM slots running dual-channel DDR4, so you fill both to get dual-channel bandwidth. Check the product listing for the supported maximum capacity and speed.
Does it have an M.2 slot for an NVMe SSD?
Yes. There is one NVMe PCIe 3.0 x4 M.2 slot for a boot drive, plus a PCIe 3.0 x16 slot for a graphics card.
Can I use this motherboard without a dedicated graphics card?
The rear panel has D-Sub, DVI and HDMI outputs, so a Ryzen processor with integrated graphics can drive a display directly. A Ryzen CPU without integrated graphics still needs a discrete card in the PCIe 3.0 x16 slot.
What does Q-Flash Plus do on this board?
Q-Flash Plus is Gigabyte's BIOS flashing feature, included here to simplify updating the board's firmware. Download the current BIOS file and follow the procedure on Gigabyte's support page for this model.
