    Excellent Mother Board!!!! Gigabyte Hit a home run with this board!!!!

    Excellent GIGABYTE Z390 UD (LGA 1151 (300 Series) Intel Z390 SATA 6Gb/s ATX Intel Motherboard Mother Board!!!! Gigabyte Hit a home run with this board!!!! Yes, it's a no frills board. No huge heat sinks, blinky cute lights, double bios or double RJ45 ports But........ It is a rock solid board with a computer user savy Bios, and downloadable win11 Bios's apps, drivers, as well as easy tuning & Overclocking tools. A well thought out board that is easy to setup & start up the first time. I noted in the reviews people having issues with heat... Not me. I set up my system with the following: Therma

    High quality, no frills.

    I purchased this for a new build centered on an Intel 9700K. I was a bit worried about power-handling as some reviews had other brands struggling to provide power to the high-end 9th generation processors. The word was that this one wouldn't have a problem, even though I favored another brand. I'll do this review in reverse.What you're not getting:USB-C - Even though it's a feature of the chipset, there is only a connector here. If you really need USB-C you would have to buy an accessory card from Gigabyte, which, I'm sure, would put the price over the cost on a board that included it. I perso

    Best Budget Board Available for Intel CPUs

    This was a solid, very forgiving board for a first-time build. Everything snapped into place easily, and after double-checking, the system booted up perfectly on the first power-up.I used the following on my build, all of which so far is working nicely:- Cougar MX330-G Mid Tower Case, w/ tempered glass window- Intel Core i5-9400 (6-core 2.9GHz w/ on-chip graphics)- Corsair CX550M 550-watt 80+ Bronze Semi-Modular power supply- 2 x Corsair Vengeance LPX 16GB DDR4 (3000Hz) RAM - yeah, I like having a lot of memory- Samsung 860 EVO SSD (250GB)- Acer SA230 FHD monitor- a Corsair gaming mouse and Lo

    Great BUT If you use it with an i7 (95W) you will need to plug the 4-Pin ATX for the CPU

    Except for the pain of having to figure out what was causing my computer freezing while gaming (which is that you need to give a little more power to the mobo, using the additional ATX 4 pin near the 8-pin one), the motherboard is pretty solid. I used it with an i5 9500 and now an i7 9700K, no issues. Great memory compatibility. It's a value motherboard but has all I need for a fraction of the cost of competitors. Taking one star off as Gigabyte should have specified the caveat about the additional power cable needed in the documentation.

    Great mid-range board for the money.

    I bought this motherboard for an upgrade build (upgrading from an ASRock e3 and and OCed i5-2750k) on Black Friday, but just got around to installing the new hardware a few weeks ago. I have to say I am very pleased with this product. I would argue this is probably your best bet for a 390 chipset motherboard if you don't want to spend > $150. The components are high quality, good slot arrangement, good features, and it will support 9th gen Intel chips if you want to upgrade lader (may require a BIOS update). Further, everything worked perfectly on the first boot, I had zero issue getting any o

    Seriously dissapointed. Chinese board Dead on Arrival.

    The product box came crushed, and full of holes. The board came warped. so warped in fact that you couldn't fit a cpu cooler on it. everything on this thing was in Chinese, and the serial number on the box didn't match up with the board.the system wouldnt post, and had a burning smell while trying to power on.I suggest taking a serious look at this seller before buying anything from them. who knows where they are getting this stuff from.

    Used for my first ever complete build, very user friendly

    I just finished completing my first every gaming build last week using this motherboard in combination with:Intel i5-9600K Processor16GB Corsair Vengeance DDR4-3000 RamEVGA FTW3 1080Ti HybridCorsair H100i Liquid Cooler512GB HP nVME SSDCorsair ML120 FanCorsair Spec-Alpha CaseThe motherboard was very easy to install for a first timer and it was easy to work my way through the manual to figure out where everything needed to go.
