The ASRock B450 Pro4 uses the AMD Socket AM4 CPU socket. Any compatible AMD CPU will have the same socket entry. It uses the DDR4 memory type, with maximum speeds of up to 3200 MHz, and 3 DDR4 slots allowing for a maximum total of 16 GB RAM.
Conforming to the ATX standard, the ASRock B450 Pro4 should fit into the majority of cases. ATX is the most common form factor, and as such has a high degree of compatibility with other components while providing a decent number of slots to widen your expansion options.
The ASRock B450 Pro4 has 6 SATA 3.0 hard drive slots. These allow for theoretical data transfer speeds of up to 6GB/s, as opposed to the 3GB/s of SATA 2.0. Generally speaking, only high performance hard drives, specifically solid-state drives, will be able to take advantage of the bandwidth potential of SATA 3.0 ports, though it is backwards compatible, so you do not have to take advantage.
The ASRock B450 Pro4 does not support onboard graphics. Any system build that uses this motherboard therefore requires a separate graphics card, or a processor that has a GPU on the same die, such as AMD APU processors. There are 1 PCIe x16 slots on this motherboard. This means it is perfectly capable of accommodating the latest graphics cards, although it is important to try and use a graphics card with the same graphics card interface of Not sure, as anything below will not reach the motherboard's potential, and anything above will have its performance slashed to the bandwidth maximum of the ASRock B450 Pro4's Not sure. The ASRock B450 Pro4 does not support multiple graphics cards via Nvidia SLI or AMD Crossfire.
The ASRock B450 Pro4 has 1 USB 2.0 slot but no USB 3.0 slots. While USB 3.0 slots are so far by no means necessary, and with a plethora of USB 2.0 peripherals to choose from, the USB functionality on this motherboard should be fine. With so few slots, however, you would have to use a USB expansion hub. As such, we would highly recommend a different motherboard, preferably with USB 3.0 functionality as well.
