Gigabytes A520I AC, AMD A520 Mainboard - Socket AM4 [A520I AC]

In contrast to the AMD chipsets B550 and X570, the A520 does not support PCIe 4.0 or 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 Gigabyte A520I AC motherboard at a glance:
- A total of 2 RGB-LED headers for connecting e.g. B. RGB strips
- DDR4 memory up to 3,200 MHz, using RAM-OC up to 5,300 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: 2x USB 2.0 / 2x USB 3.0
- A total of 3x 4-pin PWM headers for fans

The Gigabyte A520I AC in detail:
The Gigabyte A520I AC is an A520 mainboard in mini-ITX format. RGB-LED components can be connected and controlled via a 4-pin RGB header (12V) and a digitally addressable 3-pin RGB header (5V), provided they are compatible with the RGB software of the mainboard.

The Gigabyte A520I AC is equipped with a PCIe 3.0 slot in x16 format, which is directly connected to the Ryzen 3000 processor via a total of 16 PCIe 3.0 lanes. It is used to install a dedicated graphics card, but can also be used for another expansion card when using a CPU with an integrated graphics unit.

Connections for drives and peripherals
The Ryzen 3000 CPUs provide four PCIe lanes for direct connection of NVMe SSDs. With the Gigabyte A520I AC, 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 Gigabyte A520I AC has four USB 3.0 ports 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 a WLAN / BT module (IEEE 802.11ac & Bluetooth 4.2), Gigabit LAN (Realtek RTL8118AS), onboard sound (Realtek ALC887 Audio Codec) and numerous internal headers. Two HDMI and one DisplayPort outputs are provided for processors with an integrated graphics unit. An Bo (a) rd also supports RAM kits up to 5,300 MHz.
