Board Layout

The ASRock Z270 Extreme4 looks like no other board does, that's for sure. The Z270 Extreme4 might be white and black, but it is far from simple when it comes to looks. The back of the board seems plain compared to the front.


The socket area is open and ready for all sorts of cooling. There are four DIMM slots as is customary for this type of platform from Intel.


The ASRock Z270 Extreme4 has three PCIe x16 slots and three PCIe x1 slots. You can use two of the PCIe x1 slots when you have two dual-slot VGAs installed, but one will be covered by a VGA. The rear I/O panel has a PS/2 combo port, USB in a couple flavors, LAN, and audio. HDMI, DVI, and VGA are here if you want to use the iGPU built into the CPU.


What you are looking at above is a Wi-Fi port. The ASRock Z270 Extreme4 is ready to support Wi-Fi, but does not comes with it in the box. There are eight SATA connectors here, with six of them powered by the Intel chipset, while the other two are externally driven.


The board's bottom edge has headers for USB, LED strings, and audio stuffs, as well as a fan plug and the front-panel stuff.


LAN on the ASRock Z270 Extreme4 is provided by an Intel I219V controller, pictured above. There is also an ASMedia TMDS chip, the ASM1442K.
