What's Hot


Dual M.2 Slots: Not all B450 motherboards have two M.2 slots, but the B450 Gaming K4 is an exception to this. While every B450 motherboard has one X4 PCI-E 3.0 M.2 slot, most of the ones with a secondary slot operate at x2 or x4 PCI-E 2.0. However, on this motherboard that last slot operates at x2 PCI-E 3.0, which is a bit faster.


Aesthetics: The motherboard's sleek black aesthetic is perfect for those who don't want the motherboard to stand out too much. On top of that, it has some RGBs under its chipset heat sink and supports all types of RGB LED strips, including addressable ones.


SATA: The B450 chipset officially only really supports two SATA6Gb/s ports. However, vendors are taking an optional SATA Express port and making it into two. ASRock went a step further and added a dedicated controller, so you get another two. In total you can have six SATA devices running on this motherboard at the same time, your only limitation is you just can't use the second M.2 slot.


What's Not


Audio: ASRock has cut down the audio on this motherboard in both the controller used (very average) and the rear IO ports.



Final Thoughts


The ASRock Fatal1ty B450 Gaming K4 chimes in at just under $100, and that's a pretty good price for a motherboard with these aesthetics and features. It supports all the latest features such as x4 PCI-E 3.0 M.2 slots, the latest in RGB LED addressable header technology, and USB 3.1 10Gb/s.




It also sports a 9 phase VRM (6+3), but we recommend active cooling if you are going to overclock the 105W TDP CPUs. The motherboard is great for CPU's with an integrated GPU, such as AMD's Raven Ridge CPUs. That is because half the VRM is dedicated to the SoC portion of the CPU and half of the motherboard's rear IO panel is filled with display outputs. If you want a versatile motherboard that feels high-end but won't hurt your budget, take a look at the B450 Gaming K4.
