ASRock Fatal1ty X370 Gaming K4 Motherboard Review (Page 11)

Here are key points about the ASRock X370 Gaming K4.

What's Hot

Component Selection: From the IR PWM to the Intel NIC, ALC1220 audio chip, and proper USB 3.1 hardware, ASRock didn't cut corners when choosing components for the motherboard. When we drop below the $200 price point, we usually encounter vendors who cut down on PWM, audio, and networking to save a few bucks, but ASRock isn't doing that.

Two M.2 Slots: While the second M.2 slot does run at x2 PCI-E 2.0, it's still great for an SATA-based M.2 drive. Having two M.2 drives isn't something that is common, but it's a welcome addition.

RGB LED Support: The motherboard has two RGB LED headers at the bottom of the motherboard with another near the mid-point of the motherboard. The built-in RGB LEDs are also very subtle, so they don't overpower the motherboard's natural aesthetics.

Dual Internal USB 3.0: We usually tend to find only one USB 3.0 internal header on X370 motherboards, but the X370 Gaming K4.

POST-Code Display: ASRock has forgone other OC features, but they kept a POST Code display, which is an excellent move on ASRock's part to maintain value.

What's Not

Only Two Full Sized x16 Slots: ASRock decided to leave out the x4 PCI-E slot and give some of that bandwidth to the second M.2 slot. It's not a big deal, but you won't be able to use an x4 card and not use CPU lanes.

Final Thoughts

The ASRock Fatal1ty X370 Gaming K4 is a crazy good value. At $150 it encapsulates all of the X370's platform features while maintaining quality in many areas such as audio and networking. The UEFI is also solid. I wasn't impressed with the VRM power stage components, but for $150 I was surprised to find IR's control hardware in place. Compared to the Taichi you are still getting a good value.


ASRock is probably planning for a higher-end model in line with some of the Taichi's features. I saw a few empty solder pads for an extra audio codec and a bus speed clock buffer. It's also clear that ASRock has a model in mind with the WIFI card slot filled in and antennas installed. However, those features aren't required for a great motherboard, and ASRock's execution of the X370 Gaming K4 is excellent.
