The Asus Prime Z270-A is an ATX motherboard for Intel's Kaby Lake processor platform. It offers a solid mix of features and lower cost, making it a great value, while still providing Asus' respected quality.

In terms of connectivity, this board is very well rounded. It has a wide range of video outputs, with DVI, HDMI and DisplayPort all present. For memory it has four DDR4 slots, allowing up to 64GB of RAM. Drive connectivity includes SATA III, SATA Express, and two M.2 slots. It also has both analog and digital audio outputs, Gigabit Ethernet, a mix of USB 3.0 and 3.1 ports, and even a legacy PS/2 port. In terms of expansion card support, there are seven total PCI-Express slots in varying sizes. SLI and Crossfire are supported as well, though when two video cards are installed the PCI-E slots they are in run at x8 speed rather than x16.

William George (Product Development) Says:
This is a great, affordable motherboard for the Z270 platform - with all three digital video output standards. Since you can use all three of those outputs at a time, this is also a great platform for running two or three monitors without needing a dedicated video card! It also still has a legacy PS2 port for older keyboards or mice, and support for the latest connectivity like M.2 drives and USB 3.1 devices.

This motherboard can support up to (3) monitors with its single-link DVI, which supports up to 1920x1200 @ 60Hz resolution max, HDMI 1.4b, which can carry a 3D 1080p video signal at 120 Hz, and support up to 4096x2160 resolution at 24 Hz / 2560 x 1600 @ 60 Hz, and DisplayPort 1.2, which can support 4096 x 2304 @ 24 Hz / 3840x2160 resolution at 60 Hz.

This motherboard comes with (1) USB 3.1 Type A (rectangle USB shape), and (1) USB 3.1 Type C (new smaller unidirectional) connection available in the back of your system. USB 3.1 Type C is how they should have made USB ports in the first place. They will work regardless of the direction you plug them into the port, unlike how Type A needs to be put in a certain direction to fit and operate properly. This board also comes with (4) USB 3.0 ports, (1) PS/2 hybrid port, (1) Gigabit Ethernet RJ-45 port, 8.1 channel 1/8th plug ports, with (1) Optical S/PDIF output, and includes mounting spots for (2) M.2 drives.
