ASUS PRIME A520M-K, AMD A520 motherboard - Socket AM4 [90MB1500-M0EAY0]

In contrast to the AMD chipsets B550 and X570, 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 ASUS PRIME A520M-K motherboard at a glance:
- DDR4 memory up to 3,200 MHz, using RAM-OC up to 4,600 MHz
- 1x M.2 slot with x4 PCIe 3.0 connection directly to the CPU
- 1x PCIe 3.0 x16 slot for the graphics card
- USB on the I / O panel: 2x USB 2.0 / 4x USB 3.0 type A
- Internal USB ports: 4x USB 2.0 / 2x USB 3.0
- A total of 2x 4-pin PWM headers for fans

The ASUS PRIME A520M-K in detail:
The ASUS PRIME A520M-K is an A520 motherboard in Micro-ATX format. 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. Additional plug-in and expansion cards can be installed in the two PCIe x1 slots.

Connections for drives and peripherals
The Ryzen 3000 CPUs provide four PCIe lanes for direct connection of NVMe SSDs. With the ASUS PRIME A520M-K, these four lanes are used to connect a single M.2 slot for NVMe SSDs. Four SATA 6G connections are also provided via the A520 chipset.

The ASUS PRIME A520M-K offers four USB 3.0 ports with type A socket on the I / O panel. 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 are provided. This A520 motherboard also offers features such as Gigabit LAN (Realtek RTL8111H), onboard sound (Realtek ALC887 Audio Codec) and numerous internal headers. The ASUS PRIME A520M-K provides a VGA and an HDMI connection for processors with an integrated graphics unit. An Bo (a) rd also supports RAM kits up to 4,600 MHz.
