Really awesome board, beware no USB 2.0 Header for AIO's that require it.

Great board with an overclocking potential of the much larger, and more expensive Apex. No USB 2.0 header for your AIO, but otherwise an absolute gem.

Great motherboard. Perfect for my build. Just a bit pricey.

Great board. I had been waiting a month or so before it became available. With my build I felt the layout of the board was perfect. There were only 2 little minor points. The first was that the mounting bracket for the Corsair H90, collided slightly with the CPU retention bracket screw that protruded through the motherboard slightly more than was needed. I got over this due to the mounting bracket being quite flexible. The only other little minor was the AIO pump fan motherboard connector was slightly difficult to get to.

But the 2 things mentioned were really minor so I give 5 stars.

Nice but USB headers 3.0 and 3.1 not a good combination with Fractal Nano S (3.0) and Corsair H80i v2(USB 2.0). Z170i is better if you are going with these two items.

This board is very high quality and great thoughtful design targeted for iTX/SFF cases. I'm using an M.2 drive and the heatsink is a welcome addition and also the on board audio is very good. I had no issues driving my V-MODAs headphones through the inbuilt soundcard.

I chose this motherboard amid a number of cheaper options for several reasons. At the time it was ordered, I hadn't decided on an OC processor or not and I wanted to have the overclocking alternative to remain open. Another selling point was its dual M.2 drive slots, something unique to all the other 1151 itx motherboards. Most of my other successful builds, even though they were completed 10 years ago, were done on higher-end ASUS mobos and all lasted the life of the systems. Finally, I found a $10 off coupon online that clinched the deal for my first purchase from SuperBiiz for $181 delivered incl. tax.

The MB comes with a CPU mounting tool that is surprisingly useful. The tool allows for perfect alignment of the CPU, minimizing any chance of damaging it during installation. This tool holds the CPU so one's greasy fingers don't touch it and it actually gets installed permanently in the MB along with the processor.

My case has one exhaust fan and two intake fans. The Asus Z270i Motherboard only has three fan headers case, cpu, and AIO pump (not unusual for the small boards). This necessitates buying a splitter to run both intake fans together from the MB. However, the AIO pump runs the fan at 1000-1100 rpm when cold which is a little fast, I think I'll spring for a three-way fan splitter.

POSTing and entering BIOS did not go well initially. My trusty ACER monitor showed no signal for the first half-dozen of attempts but eventually the BIOS screen appeared. Entry into the BIOS was still intermittent but eventually became consistent after about an hour of fiddling. Once Windows 10 was installed, the machine booted consistently every time. Boot times are about 20 seconds from the NVMe drive.

On board sound of this board is very rich and satisfying. Even my high-end Bose speakers made for average noise on my old Dell. This new board features 8-Channel high definition CODEC audio, however, and the sweet Bose have now been unleashed as the booms of my guns and explosions of my impacting shells are very satisfying, as is the in-game music and ambient sounds.

Very pretty and performs well. I'm removing a star because I had to replace the first one for coil whine (on a motherboard? really?) during stress testing. Even the replacement board has a teeny tiny bit of whine during Prime95/Realbench, albeit less loud than the CPU cooler. Since I have another 30 days until my return policy expires, I may RMA it one more time to make absolutely sure, but if I don't then it's still fine.
