So I had the chance to check out our first ITX Z270 board with the Gigabyte Z270N Gaming 5 just last week. As soon as I was done testing, I swapped it out and jumped right into the second board that came in, the Asus Strix Z270I Gaming. This board was sent specifically for an upcoming project build, just like the Asus Strix GTX 1080 11Gbps that I also took a look at last week. While I wait for a few of the last components for the build I wanted to take a closer look at the board and make sure it was going to be what we are looking for.

Packaging and Accessories

The packaging for the Strix Z270I might be ITX sized, but Asus did still get all of the normal Strix branding on the outside, just like with the larger boards. You have the ROG logo up in the top right, the Asus logo in the bottom left, and a large Strix logo in multiple colors across the front. Also on the front is a photo of the board, something I always love to see so that people in retail stores actually know what they are buying. The back of the box has a short specification listing with a photo of the board from the top down. There is a second photo that is at an angle to show the rear I/O connections as well. Then down below are four other photos that highlight key features.

There is something about when you buy a product and you get more than just the basic things. Getting a lot of accessories isn’t seen as often but it really makes you feel like the company didn’t hold back. For the Strix Z270I Asus went crazy with accessories. For documentation, you get a large manual, a CableMod coupon, and a driver/software disc. Beyond that, you get a large sticker sheet and cable labels with the ROG logo on them in different colors.

image 3

For physical accessories, there is a whole pile. The rear I/O panel is standard but the blacked out look and the padded back over the metal springs is a nice touch. You get four SATA cables with two out of the four with a right angled connection on one end. There are two M.2 mounting kits and they also include a CPU installation kit and a ROG coaster as well. Because this board has Wireless you also get an antenna with a magnet inside to mount on your case. Being an ITX board Asus includes a short lead for your front panel connections to let you plug them away from the board then plug it all in at once. Then last but not least is an RGB extension cable.

Board Layout and Pictures

So when it comes to ITX boards, a lot of the designs end up looking a little plain when compared to all of the crazy full ATX options. The reason is with ITX they actually have to work to pack in features, so a lot of the flashy stuff has to go to make that work. With the Strix Z270I, you can see where things aren’t as flashy but they did manage to slip in a few aspects of the Strix styling. The board itself has a flat black finish in the areas that you can see it and they have that medium gray finish on the two main heatsinks as well as the cooler over top of heatsink over the M.2 slot. The overall layout is like most high-end ITX boards, you get one PCI slot, two ram DIMMS, and a CPU socket in the middle with anything else packed in any other gap. After checking out the Gigabyte ITX offering I do with Asus would have gone with a cover for their rear I/O as that makes a big difference when you don’t have the metal I/O against the black PCB.

image 12

image 13

The cooling isn’t as crazy as on an ATX board but the Z270I does have the two small heatsinks around the CPU socket to handle the power circuitry. They have that angular Strix styling, the same finish as normal, and they even put a small Strix logo on one. The M.2 cover was unexpected and it ends up adding a lot more to the look of the board. I’m still a little skeptical of M.2 coolers as a whole, but this one does have full contact with the entire M.2 drive. The ROG logo and the touch of black looks good on it also.

image 14

image 15

Being an ITX board we don’t really have to break it down in to many sections and really most of the connection options are all along the right edge anyhow. You have the two DDR4 DIMMS with the 24 pin motherboard power right next to it up near the top of the board. The four SATA ports are split up but all still mostly in one area and they are next to the USB 3.0 header. The front panel connection almost looks like a USB 2.0 header and is above the SATA ports along with the white RGB header for Aura Sync. There isn’t a USB 2.0 header at all though.

image 18

Up on the top left near the rear I/O panel they slipped in a 4-pin fan header and the 8-pin CPU power. They did also slip the new style USB 3.1 header right up next to the I/O, it is easy to miss.

image 19

The onboard audio has almost no room but you can find it in the bottom left corner of the board just next to the PCIe slot. There is just the one cap visible and then you have a metal cover with the SupremeFX logo on it covering the S1220A Codec based chipset. There are two headphone amplifiers tucked in just above. Then the front panel connection is right above them.

image 17

Then the PCIe slot down on the bottom edge is what brings it all together. Without it, you can't run dedicated graphics and have badass gaming rigs in the small form factor. This is a full x16 slot because what else would it need to share the bandwidth with right?

image 16

The rear I/O has a lot going on. From here we can see a few more of the audio caps next to the standard 5 plus an optical layout. Next to that is the Wireless AC and Bluetooth antenna connections. The wireless card is actually built right into the I/O panel and not visible on the board like Gigabyte’s ITX board had. It not only looks better but saves space as well. Being Z270 we still need display connections, so you get a DisplayPort and HDMI for the onboard video. The red network port means it has Asus’s built in surge protection on the Intel I219V based NIC. Then for USB, you get one new Type-C port and three Type-A ports all running USB 3.0, not 3.1. Then the four USB 2.0 jacks. I love that there are more USB connection options than a lot of boards as that is really important to me. Overall it looks like Asus did a good job filling in the entire Rear I/O.

image 20

The back of the board gives us a better look at that flat black PCB. Beyond that, the second M.2 slot on the back is the only other thing going on. This and the front M.2 both support x4 bandwidth and one of the two is also listed to support SATA M.2 drives as well but the specifications aren’t clear which does.

For the BIOS I finally get to show off our new capture card rather than the terrible BIOS photos I have been using over the years that in addition to being bad, I also have to spend way to much time editing to even get to the level they were. So to celebrate that here is a shot of the boot screen on the Z270I.

Moving into the actual BIOS I was happy to find that Asus takes up into their EZ Mode BIOS first. For some reason, a lot of boards have this feature but then don’t even take you to it out of the box, how is anyone who doesn’t know there way around going to find the mode made for them. Anyhow You have the red and black ROG theme going on. You get a quick way to drag and drop boot drives over on the right (even though I didn’t have a book drive installed when redoing our photos). You can turn on XMP Rapid Storage, and get into your fan profiles. Beyond that everything else just tells you about your setup like the information on your BIOS revision, CPU and memory information, and temperatures and fan speeds.

software 1

Getting into the advanced BIOS basically gets you CPU, Memory, and Voltage information over on the right on every page. The main page has more CPU, Memory, and BIOS information as well as the ability to change your language.

software 2

The Ai Tweaker page is basically where you will find any and all overclocking options from voltage settings farther down the page, clockspeed settings, multipliers, and memory overclocking settings as well. Basically one stop shopping for all overclocking.

software 3

The Advanced tab has a whole list of additional pages you can get into. They basically cover USB settings, onboard device configurations, and other platform specific pages. In other words, every option that isn’t related to overclocking, especially anything run by the chipset.

software 4

The Monitor tab basically lists off every reading your board is picking up. You can flip through and see all of your temperatures, voltages, and fan speeds here.

software 5

The Boot tab is where you need to get at any booting specific settings, especially boot priorities and you can also just go here to one time override and boot from any other drive.

software 6

The last tab basically has all of Asus’s other tools. You have BIOS updating with EZ Flash 3. Secure Erase securely erases hard drives and SSDs. You can save multiple overclocking profiles here, this is nice for having a stable version and something you are testing or just having profiles depending on winter and summer if your PC gets warmer in the summer. Then up on the top edge of any page, you can also get into the EZ Tuning Wizard where it will do a mild overclock for you. Or you can also open up Qfan Control. AI included a photo below, basically, you can change and tune fan profiles for any fans connected to your PC. You can do the same thing with the windows based software, but this way you don’t have to even have the software installed if you want.

I always like to point out that basic benchmarks typically don’t show much of a difference between motherboards with the same chipset. Frankly, a lot of the testing you see in reviews anymore mostly just shows that you ran the board at all. I personally run a few tests to make sure nothing is out of line, but I don’t stress the differences when they are close. All of the boards have been tested with the exact same GPU, CPU, and Memory and unless you are overclocking those are the parts that set our stock performance. That said the Z270I, even though it is a much smaller board than most of the boards tested, performed on par with the others and seems to be in line with the competition.

I did test out the Network performance, both on the wired Intel NIC and the Wireless AC. This is one of the few areas that you see some variation due to different network cards being used and with wireless, even the antennas make a difference. Wired the Z270I was basically right in line with the other fastest board that was also an Asus board using an Intel NIC. On wireless, I saw a bit more performance compared to the other boards tested with wireless AC. More importantly, unlike the Gigabyte board, the Z270I didn’t have weird fluctuations in the wireless signal and performed extremely well in the exact same testing situation.

Overall and Final Verdict

So with Z270, I have been impressed with Asus’s offerings basically across the board. The current Strix styling really fits what I like to see in a board with the color neutral styling, angular but not overly aggressive touches in the heatsinks, and RGB that isn’t too overboard or in your face. Asus managed to keep all of that while shrinking everything down. I didn’t touch on it too much in my testing but the right edge of the Z270 I has Asus’s Aura lighting that has individual LEDs that have a nice effect even set in the basic mode. The performance was as expected and in the case of the wireless it was noticeably better than the Gigabyte Z270 board that I just recently reviewed.

That does bring me to an area that I would love to see Asus work on next generation. The Gigabyte board had a rear I/O cover and it made a huge difference in hiding the metal I/O panels. I didn’t realize it but with ITX boards the I/O stands out even more. Beyond that though, I like that nearly all of the connections were along the right side, that should help keep installation simple in those SFF builds. They also included a crazy amount of accessories with this board. It really makes you feel like you are getting something special.

image 23

image 24

All and all, the Strix Z270I performed well. Because I was already planning on using it in a future build I also went ahead and installed it there. This is where I really ran into the issue of not having an internal USB 2.0 header on the board. While the water cooling for the build will be changing in the near future, I wanted to keep the fans. The problem I ran into though was Thermaltakes fans have to be connected to USB to be configured so I will have to work that issue out in the future.

That said I do think my decision to go with this board for the build is still a good one. It best fits the look I’m going for and beyond the USB 2.0 header issue, it also has all of the features I need. It should also age well. It has the new upcoming USB 3.1 internal header and two full speed x4 M.2 slots for those ultra fast NVME SSDs and to get fast connections up on the front panel of your case in the near future. Really the only other downside is the price. With all of the accessories and features you get, Asus has priced the board to match at $179.99. There are still lots of ATX boards that are more expensive, but when I last looked this is the most expensive ITX offering. I was hoping to see an Impact board on the Z270 chipset but as of yet I haven’t seen anything on one so the Strix Z270 I could very well stay at the top for ITX offerings all year.
