Socket Type Intel LGA 1151
Chipset Z270
Form Factor ATX
Year Released 2017
CPU Support Kaby Lake / Skylake
Expansion Slots 6 PCIe, 6 SATA, 3 SATA Express, 2 M.2, 1 U.2
RAM Slots 4 x DDR4
Maximum RAM 64GB

The Z270X-Gaming 5 by AORUS won't break your budget and it comes packed with a lot of sought after features and a strong spec list.

To begin, this model features an 11-phase CPU power design. It has three reinforced steel PCI-E 3.0 x16 slots and support for 3-way CrossFireX or 2-way SLI. It also features PCI-E 3.0 x1 slots, and multiple SATA 6Gb/s ports one U.2 port, and a two full-speed PCI-E 3.0 x4 M.2 slots. It supports Intel's Optane SSD line of products. As far as USB goes, there are two USB 3.1 ports, a Type-A and Type-C port. It comes with several USB 3.0 ports, a couple of USB 2.0 ports, and headers.

RGB Fusion

It has a vibrant and exciting LED light implementation that makes it stand out from other similar motherboards. You will find RGB LEDs located under the audio section as well as beneath the chipset cooler and between the PCI-E slots and CPU socket. These can be programmed for each to display a different color or lighting effects.

It is also possible to add aftermarket lighting. This is unique as it negates the need for an external controller or power strip. This streamlined "we thought of everything" approach not only saves you money but allows the system to perform more efficiently.

The Fusion application makes it possible for users to fully control all of the LED lights. You can create cool effects such as timing it to blink in time to music, fade on and off, cycle through, or strobe. The effect, overall, is visually stunning.

Onboard Audio

With fewer consumers purchasing sound cards, this feature is more important than ever. The Z270x Gaming 5 was tested for quality in a number of areas including noise level, dynamic range, THD, IMD and stereo performance. The analogue signal quality of the unit is good to excellent across the board.

M.2 PCI-E 3.0 x4

The high-performing NVMe PCI-E combines Samsung's state-of-the-art UBX controller with the industry favorite 3D V-Nand and as such has the capability of matching or exceeding the average transfer rates. One cool feature of the Z270x is that it has two M.2 connectors, which means fewer cable management problems. You can also RAID the two together.

The performance of the M.2 slots is excellent. They perform with consistency coming close to that of the PCI-E slot. Transfer rates are consistent regarding IOPS, as well. This factor indicates that you can expect optimal performance when using an M.2x4 solid state drive.

Auto Overclocking

This model of the Z270x features three types of auto overclocking. Two are software based, and one is BIOS based. Use the EasyTune app to access the OC presets and the auto-tune feature. The preset is simple and straightforward, just click, and the system reboots applying the overclock. When using auto tuning you can slowly increase the system frequencies, perform stress testing at each level until the limit is reached. The entire process takes fewer than 10 minutes.

It also looks good with the attention given to detail in the RGB lighting array. Regarding overclocking ability and audio quality, it overachieves, making the Z270X Gaming 5 a best in its class pick for the mid-level range of motherboards.

Pros Cons
The RGB Fusion system allows complete customization of the LED lighting on the board No DVI-D port
Strong overclocking capabilities  
Six onboard temperature sensors and two temperature sensor headers  

200 Series Chipset Features

Intel’s upcoming 200 series chipset motherboards are expected to be released at the same time as Kaby Lake CPUs, which looks like being January 5, 2017. 200 series chipsets, such as the Z270, H270, Q270, Q250 and B250, will allow compatibility with Kaby Lake processors. Crucially, they are also compatible with Skylake CPUs, and Kaby Lake CPUs are compatible with Z170 motherboards with a BIOS update. This kind of cross-compatibility is a very handy thing indeed, and gives PC enthusiasts and gamers more options when upgrading or building a new machine. Intel’s Cannonlake and Coffee Lake lines of CPUs, due to be released in late 2017, are said to be compatible with socket LGA 1151 motherboards.

While there are no major improvements to the 200 series chipsets over the 100 series chipsets, there are a few minor updates that are worth mentioning. Intel Rapid Storage Technology (RST) has been upgraded to version 15 which should lead to improved performance and reliability of SSDs and SSHDs.

Intel Optane Technology Support

The new line of chipsets also have support for Intel Optane Technology, which will feature in upcoming SSDs based on 3D XPoint memory technology. Optane SSDs are expected to provide 5 – 10 times improvement in performance over standard SSDs. Intel will release some Optane Storage devices in 2017, however they are likely to be small in size (32GB) and expensive meaning it will probably be sometime before the technology is mainstream.

200 Series Chipsets Feature More Storage Options

Another improvement in motherboards that feature Z270 and H270 chipsets is the increase in PCI-E 3.0 lanes, with an extra 4 lanes compared to the Z170 and H170 chipsets. These allow for additional high bandwidth connections to be used, such as extra Thunderbolt, USB 3.1 or graphics cards. Z270 has a total lane budget of 30 compared with Z170’s 26, with the total PCI-E 3.0 lanes up to 24, compared with 20.

Z270 chipset motherboards can support a maximum of 3 M.2 slots, which is the same as Z170 chipset motherboards. H270 doesn’t have any increase in the maximum M.2 slots over H170, staying at 2.

Intel make the distinction between Z270 as an enthusiast platform and H270 as more of a budget platform by allowing overclocking and multiple GPU setups on Z270 chipset based motherboards only. H270 motherboards are relatively cheaper as a result.

Kaby Lake Features

core i7 7700K is the best kaby lake cpu

Kaby Lake is the codename for Intel 7th generation processors, succeeding the Skylake line of CPUs. It has faster clock speeds than Skylake, and higher turbo frequencies. While the i7-6700K is the top processor for Skylake, the i7-7700K is the CPU at the top of the Kaby Lake range. Kaby Lake’s Core i5-7600K is the direct replacement for Skylake’s i5-6600K.

Kaby Lake Uses A 14nm+ Process

The Core i7 7700K is a quad-core hyper-threaded CPU that uses the same 14 nanometer manufacturing process technology as the i7 6700K Skylake CPU. Intel is actually calling this process 14nm+, and it is currently the most advanced form of the 14nm node which will bring up to a 12% increase in performance over Skylake.

USB 3.1 Gen 2, Thunderbolt 3 and Improved Graphics

Kaby Lake features a number of improvements over Skylake, with fully integrated support for USB 3.1 Gen 2 enabling bandwidth of up to 10Gbp/s rather than 5Gbp/s, and native Thunderbolt 3 support added too. HDCP 2.2 support has been added to Kaby Lake processors, along with a new graphics architecture which improves performance in 3D graphics and 4K video playback.
