ASRock, the first series of A520 motherboards aims at small systems
ASRock A520M-ITX / ac The A520M Pro4 is the only one to offer four DDR 4 memory slots, which means you can install up to 128GB of RAM. The remaining motherboards are limited to two slots, so the maximum capacity is 64GB. Regardless of the model, however, all ASRock A520 motherboards support memory modules up to DDR4-4733 and above.
The A520M Pro4 is equipped with an eight phase power subsystem, while the others four motherboards feature a six-phase design. Of the five micro-ATX offerings, only the A520M / ac has Wi-Fi 5 and Bluetooth 4.2 connectivity.
Each of ASRock's A520 micro-ATX motherboards comes with four SATA III connectors and at least one M.2 PCIe 3.0 x4 slot. In the case of the A520M Pro4, the motherboard has two M.2 slots.
The cards offer different expansion options, so you will need to take a thorough look at their technical characteristics to find the one that best suits your needs. For example, the A520M Pro4 only provides two PCIe 3.0 x16 slots, while the A520M-HDVP is more generous and offers one PCIe 3.0 x16 slot, two PCIe 3.0 x1 slots, and even one regular PCI slot.
ASRock A520M / ac ASRock A520M-HDVP The A520M-ITX / ac should prove to be a good option for small form facto r (SFF) PC builders looking for a quality product. The motherboard employs a capable eight-phase power subsystem to accommodate the latest and future Ryzen CPUs effortlessly. Memory support is the same as that of micro-ATX cards, but thanks to shorter lines to the processor, the A520M-ITX / ac should offer good performance for RAM overclocking.
