Good board. Enough fan headers for most people.

A simple and straight to the point motherboard! No flashing lights or anything that'll get in your way when it comes to building. My only gripe is that with the standoffs, there are 3 spots that it requires you to NOT have standoffs installed. Putting it into the case was a little bit of a challenge... but great for what it is already.

Pretty good motherboard which will be able to handle a higher chip later just could use some more USB ports.

It was cheap and has all the features I need. It supports 3000 MHz ram out of the box. But one huge flaw is the brown PCB. Thankfully my Corsair 270R has a tinted side window, so I cannot tell that it's brown when the case is closed. I would not have bought it otherwise.

from completed build My Dad's Gaming PC

This is a great board for the money. It comes with multiple USB 2.0 headers and one 3.0 header, four fan connectors, two PCIEx16 slots, and hefty VRM coolers.

My dad is a bit of an old school guy, so I went with a full ATX board in case he wanted to add extra cards to the other slots (sound, USB cards, etc.)

Great motherboard with multiple fan headers. Supports 3000 mhz ram. Looks nice and simple in my opinion.

Great specs. Great price. The software is valuable and really easy to use. Everything installed during the build with absolutely no problems.

Great board for the price. Only missing features are offset voltage control and better fan control with profiles.

MOBO has all the connections you need, plus more. Easy, intuitive bios. The brown coloring is a little painful to look at, but it is hard to notice in a dark case. Don't get too big a fan though, it might not fit!
