    Great board

    Great board. Just upgraded to AM5 and sold this on eBay and probably made back close to what I bought it for 6 years ago.

    Second attempt at Z390 Board

    Bought a Asrock Z390 Pro, and was a dud on installation, wasted 3 hours trying to figure out what was wrong. Now with the Gigabyte Z390 Gaming X and I5-9400F. Board installed nicely, liked all the connectors marked and the color coding of the connectors. The Asrock was only black and white. I like how Gigabyte installs the backplate on the board to simplify things. Board comes RGB lighting, which wasn't a critical point for buying the board, but actually enjoy the looks of it. Colors can be changed with app in Windows. Board works good, and I have no complaints. I've found Gigabyte always buil

    Perfect choice. Strong component.

    I don’t really understand the ratings they give for this item, “warmth, thickness and sheerness” none of those describe what this product is meant/used for.I’m very happy with this though. I bought it forever ago and my husband was finally able to put it in my computer with a new processor. I am loving it!It was such a nice upgrade and my computer runs much more smoothly now. I was having trouble with windows crashing every now and then, and updates wouldn’t fully complete, but the first update on this went through just fine!So happy I went with this one rather than some of the others I was lo

    Solid board with a few small bugs. Limited audio, confusing but adequate bios.

    It's a solid board. I installed an Intel 9900k. Looking over the construction, the capacitors look decent and the traces on the board are fine. I would rate the flex as medium, I would prefer a bit more thickness but it is fine.My board arrived used, and the screws and offsets were missing, even though I bought it new, but hey, it works and I'm not going to eat off it Still, weird. Not a great job either by Gigabyte or Amazon, don't know what happened there. I had offsets from a previous build so whatever.The bios still has some bugs even with the latest firmware. It doesn't always remember al

    Great product at reasonable price

    I decided to build my new pc around a used 9600k I got from a friend. Everything worked great.Was able to OC my 9600k to 4.8 Ghz and stay around 75oC under heavy load/gaming with a 120mm AIO.All 4 dims of ram worked, switched from 1-3, to 2-4 just to test 8GB x2, XMP enabled at 3200Mhz.M.2 NVME SSD worked great, and motherboard includes a cooling pad.Gigabyte software RGB Fusion worked to switch color and mode for RAM and AIO.Really liked the design and features and would recommend if you can find it for around $130-140.

    One issue, but fixed now

    A great mobo for this price, has some of the latest features, the only thing i dont like so much is that it only has 1 usb 2.0 header and usb 3.0 header, wish it had more, but for like 20 to 30 dollars i can get a usb hub for it, had 1 issue but has gone away after i boot it a few times, like it would turn on then sit on a black screen, then i would turn off and turn back on and it was fine after. And dont under clock a i5 9600k, i tried and the system failed to boot and i had to clear CMOs to fix, i tried to under clock to see if it would affect the temp's in the system because i was using a

    Quick ship, seller had the right stock!

    I had another LGA 1151 motherboard that many years after purchase we figured out it had a bad memory slot, and this was to replace it. Worked a charm!

    Excellent Amazon Warehouse deal

    I love shopping Amazon Warehouse. It is like a spin of the wheel. When it hits, it usually hits very well. And when it misses? Well.....This one was a hit.Timely delivery and excellent open box deal. Was described as, "Used-Good," but looked near brand new with pack in materials included.I had ordered two other Gigabyte (Aorus) Z390 motherboards from the Warehouse that were defective. I had ordered this one as a safety net and I'm glad I did.I actually really like the minimal lighting on it that is VERY clean in look and design and handled a 5.2 overclock on a 9900k no problem.
