ASRock B450M PRO4 AM4 AMD B450 SATA 6Gb/s USB 3.1 HDMI Micro ATX AMD Motherboard

This motherboard, even small is in par with most of the ATX motherboards with the same B450 chipset. The B450 chipset features the AMD StoreMI technology, StoreMI moves frequently-accessed files to the faster drive to improve important things like boot and program loading times, providing users flexibility. Overclocking is still supported with this chipset. Supports AMD AM4 processors (Pinnacle Ridge, Summit Ridge, Raven Ridge). DDR4 memory compatible, up to 3200+ MHz (OC) (depends on your processor). Four SATA 3 interfaces and a single Ultra M.2 slot and a regular M.2 slot.
