The ASRock Z270 Extreme4 motherboard brings features that will satisfy the needs of most users, without bells and whistles that usually only raise the price of the product with no real benefits.
Besides thes basic features of the new chipset, it brings two SATA-600 ports and a pair of USB 3.1 ports (one type A and one type C), and programmable RGB lights.
The Z270 Extreme4 has a high-end audio interface, and the fact it brings three M.2 slots (one for Wi-Fi cards and two for SSDs) is an excellent addition. The twelve-phase voltage regulator brings stability and durability to the motherboard.
The only characteristics that may be missed by enthusiast users are the support to SLI with three or more video cards (which is actually not even recommended) and the presence of auxiliary overclocking features like power, reset and clear CMOS buttons, and a POST error code display.
So, if you want a robust motherboard with high quality audio to build a workstation or gaming PC using a sixth or seventh generation Intel Core i CPU, using up to two video cards, the ASRock Z270 Extreme4 is a great choice with excellent cost/benefit ratio.
