Fantastic motherboard. Drivers a bit slow to load, but sound is great and it has two chasis fan slots
By Jeremy Elliott
Great for my first ever build, affordable kaby lake option
I used this for my first ever build, it is a affordable kaby lake compatible matx mobo that offers many of the benefits and features of a full size, but in a smaller form factor and much more competitive price. I really like the fact that this model has a usb 3.1 port as well as usb c, this will be important in the coming years for device compatibility. Another plus is that it has 4 dimm slots for ram, so you can have a max of 64gb. It comes with the i/o shield, and 2 sata cables. Overall, a pretty well rounded mobo, with some nice bells and whistles, but without breaking your wallet.

Great systemboard for i3
I haven't built a pc in 15 years. I remember setting jumpers and having to struggle through weird quirks during installation. I'm glad those days are behind me. This system board was a breeze to install and configure. The bios uses a very simple and easy to use gui that is controllable via keyboard and mouse. I used this with a 7th gen i3 processor, ddr4 memory and a m.2. Ssd as a boot device. Windows 10 recognized every device during installation. I would definite buy asrock again.
By Marianne Fortin
Looks nice, several flaws.
Decided to buy this asrock b250 motherboard because i've always trusted them to be reliable and full of features. Here's some pros and cons.Pro's:got it at a discount ($70ish)has rear io cover so it looks nice2 pci-e ssd m.2 slotsplenty of fan headerswhite accents that look greatcons:no xmp supportno ram speeds higher than 2400mhz supported, or even possibledifficult uefi to navigatemotherboard mount for second usb 3 header, but no header (see images)significantly higher voltages than my lowly 7100 needs on bios version p1.50
By Lori Caldwell
Great bang for your buck.
Picked it up for 79.99, for a kaby lake, black and white build. My requirements were m.2 for an nvme ssd, support for i7 7700, and ddr4 support. This thing flies!! I swear it boots in 5 seconds. If you don't pick up at least an intel 600p name ssd for a boot drive, your a fool. Note: leave all other hdds unplugged until after you install windows, or it will throw an error. Basically it only wants to install sata0.Really i only have one con. The white io cover prevents installation of my aukey pci-e wireless card in the second pci-e slot. The card won't seat fully, the card has .4 inches of card that is blocked. I think i'll just dremel out a hole so the card fits... I know you can take it off, but i'm not uninstalling everything just to remove the io covering.All in all, i love it. Had everything except built in wireless
By Amalie Madsen
Easy build, feature rich for price
After two boards from another a brand sold by the hen fruit company failed to post, i came to outletpc and bought this. Put an i5 7500 in it with a zotac gt730 and it is fast and quiet. Once you know, you buy from outletpc.

I love
Motherboard e is excellent of easy configuration and with native video card it does not use ram memory besides other uses
