ASRock Z370 Killer SLI/ac Motherboard Review

Verdict and Conclusion

In conclusion, the ASRock Z370 Killer SLI/ac motherboard is a decent performer that’s designed and aimed at the mainstream user. Even though it’s not an enthusiast motherboard, it kept up with the Asus ROG Maximus X Hero (a motherboard that costs twice as much) in all our benchmark tests.

What about the extras? Well, it does come with a decent set of features, that will allow you to plug and go right away, but don’t expect to any enthusiasts features. There’s no diagnostic LEDs, power-on or reset buttons. I do like the 2 x M.2 connectors and the PCIE steel slots, as well as the simple plastic hood for the I/O panel.

For overclocking, it was pretty modest. I’m not an extreme overclocking enthusiast … but I was able to overclock the Intel Core i7-8700K from the default speed of 3.7GHz to a acceptable 5.0GHz. Temperatures was extremely high during our full load tests … so I highly recommend a custom water loop (or a powerful AIO) with a large radiator.

Price-wise, the ASRock Z370 Killer SLI/ac is one of the most affordable Z370 motherboard on the market, making it extremely attractive for the budget or mainstream user.

You can buy  the ASRock Z370 Killer SLI from Newegg for USD $150 or buy something similar – ASRock Z370 Extreme4 for around USD $195 from Amazon –



  • Supports all Intel 8th Gen processors (Coffee Lake)
  • Decent performance
  • A good set of features
  • Extremely affordable


  • For that price – none I can think of


Final Thoughts:

Are you on a budget but want an affordable Z370 motherboard for your Coffee Lake processor? And do you want a decent feature set for gaming, with the option to do a little mild overclocking? If the answer is yes to both of these questions … then take a look at the ASRock Z370 Killer SLI/ac . It offers decent performance at a price that’s extremely affordable.
