ASRock A520M Pro4, AMD A520 motherboard - Socket AM4 [90-MXBDU0-A0UAYZ]

In contrast to the AMD B550 and X570 chipsets, the A520 neither supports PCIe 4.0 nor overclocking. Mainboards with the A520 chipset support PCIe 3.0 and offer office and home users a reliable basis for their PC.

The features of the ASRock A520M Pro4 motherboard at a glance:
- A total of 4 RGB-LED headers for connecting e.g. B. RGB strips
- DDR4 memory up to 3,200 MHz, using RAM-OC up to 4,733 MHz
- 1x M.2 slot with x4 PCIe 3.0 connection directly to the CPU
- 1x M.2 slot with x2 PCIe 3.0 connection to the chipset
- 1x PCIe 3.0 x16 slot for the graphics card
- USB on the I / O panel: 2x USB 2.0 / 5x USB 3.0 type A / 1x USB 3.0 type C
- Internal USB ports: 4x USB 2.0 / 2x USB 3.0
 -A total of 6x 4-pin PWM headers for fans

The ASRock A520M Pro4 in detail:
The ASRock A520M Pro4 is an A520 motherboard in Micro-ATX format. RGB-LED components can be connected and controlled via two 4-pin RGB headers (12V) and two digitally addressable 3-pin RGB headers (5V), provided they are compatible with the RGB software of the mainboard.

A PCIe 3.0 slot in x16 format is available for graphics cards, which is directly connected to the Ryzen 3000 processor via a total of 16 PCIe 3.0 lanes. A PCIe x16 slot with two PCIe 3.0 lanes is also available for plug-in and expansion cards.

Connections for drives and peripherals
The Ryzen 3000 CPUs provide four PCIe lanes for direct connection of NVMe SSDs. With this A520 mainboard, these four lanes are used to connect a single M.2 slot for NVMe SSDs. The second M.2 slot is connected to the chipset with two PCIe 3.0 lanes. Four SATA 6G connections are also provided via the A520 chipset.

The ASRock A520M Pro4 offers six USB 3.0 ports on the I / O panel, five of which have a type A socket and one with a type C socket. USB 3.0 or USB 3.2 Gen 1 achieves maximum speeds of 5 Gbit / s per port. In addition, two USB 2.0 ports and a PS / 2 connection for a mouse or keyboard are provided. This A520 motherboard also offers features such as Gigabit LAN (Realtek RTL8111H), onboard sound (Realtek ALC1200 Audio Codec) and numerous internal headers. For processors with an integrated graphics unit, one VGA, one HDMI and one DisplayPort output are provided. An Bo (a) rd also supports RAM kits up to 4,733 MHz.
