If you’ve got 24.4 x 24.4 cm worth of motherboard tray to fill, which Z370 motherboard should you get? Well, your options here are extremely limited, there are three ways to go that I’m aware of, and just one of them makes sense.
The Asrock Z370M Pro4 is the obvious choice as it’s the MicroATX version of the similar sounding Z370 Pro4 that we looked at earlier. Priced at $130 you get a very solid VRM, 4-DIMM slots, 6-SATA ports, Intel Gigabit LAN and two PCIe 3.0 x16 slots, though of course the second is only wired for x4 bandwidth.
For considerably more, the Asus ROG Strix Z370-G Gaming can be had at $185, but you’ll be hard pressed to work out what you’re getting for the extra $55. Asus does have a better audio solution, you also get wireless networking and a few extra USB ports. That said you also get tightly packed PCIe x16 slots and VRM heatsinks without proper fins.
Then there’s the insanely underwhelming EVGA Z370 121-KS-E375-KR. You have to wonder how EVGA came up with that name, but that aside, for an expensive $200 you get Intel Gigabit networking, no wireless, a basic Realtek ALC1220 codec, standard storage and basic a USB configuration, no Type-C. Crazy, but not at this price point, thank you very much.
So Asrock and their practical Z370M Pro4 win this category, almost by default.
