★★★★★Beautiful board but do read my review incase you get atx case!!
Absolutely amazing! Looks great does everything you will need it for. I’m running it with my 4080 strix and 7 5700x3d for 4k gaming in my 011 vision compact. And yes, you will want to vertically mount your card if you plan to use a m-atx in a full sized atx case 😅

★★★★★Not worth it.
Took way longer then noted to get here, seller would not respond to messages, motherboard is very cheaply made and runs very slow.

★★★★★Got exactly what I ordered brand new!
Great AM4 board! Doesn’t come with wifi or Bluetooth so you will have to get adapters, but still an amazing motherboard! Comes brand new in the box with an anti-static bag!

★★★★★Failed to post!
The problem with this motherboard is after everything is installed [ CPU & GPU ] it won’t post, there no indication lights to show you where the problem is. If you plan on buying this, buy the extra warranty otherwise you’ll be disappointed had you not purchased the extra warranty. Nice board but needs work an upgrading.
