Earlier this year, Intel released their latest Kaby Lake processors and the new Z270/H270 chipsets to accompany them. Myriads of motherboards based on these two chipsets have been released during these past couple of months, covering virtually all of the consumer market demand.

In this review, we are having a look at two cost-effective Z270 motherboards that have been designed with gamers in mind - the MSI Z270 SLI Plus and the ASRock Z270 Killer SLI. As their names suggest, these two motherboards mainly place their marketing focus on the SLI support, and both have a retail price of under $140. We will examine their features, differences and performance in the following pages of this review.

In comparison to the older Z170 boards, the new Z270 board on the base specifications are hardly any different. The Z270 ones have four extra PCIe lanes configurable on the chipset, potentially new audio and new networking controllers, and Intel Optane Technology Support. Although four extra PCIe lanes does sound like a huge difference, it is an important upgrade for the implementation of native M.2 slots (on Z170-based motherboards, this usually meant disabling some other device/port on the motherboard). Also, note that Intel Optane drives should still function on other chipsets as drives; the Z270 only allows them to enable their “smart caching” technology.

Individual motherboard manufacturers will be sprinkling on new features onto their Z270 products to aid the transition and provide other tangible benefits over the old platform.

To read specifically about the Z170 chip/platform and the specifications therein, our deep dive into what it is can be found at this link.

MSI Z270 SLI Plus Overview

The MSI Z270 SLI Plus is a motherboard trying to implement as many practical features as possible while keeping the price tag below $140. It has two M.2 PCIe 3.0 x4 slots, with one of them supporting M.2 devices up to 110 mm long, and a total of six SATA 6Gb/s connectors. There are no native U.2 connectors but U.2 drives can be connected to the M.2 slots by using appropriate adapters. The new Z270 chipset allows the two M.2 ports to operate PCIe devices without disabling anything on the motherboard, but the use of SATA M.2 drives will disable one SATA port for each drive. MSI also implemented the new Realtek ALC1220 audio codec, as well as the competitive Intel I219-V Gigabit LAN chipset. A TPM header is also present.

The number and type of USB ports on the MSI Z270 SLI Plus can be a little confusing. The motherboard’s specifications state that the motherboard has one USB 3.1 Type C port and five USB 3.1 Type-A ports on the back panel, plus four USB 3.1 and four USB 2.0 Type-A ports available via headers. Once you read the specifications more carefully, it becomes apparent that the unnaturally high number of USB 3.1 ports is due to MSI dubbing the USB 3.0 ports as “USB 3.1 Gen 1”, while the 10Mbps ports are the “Gen 2”. They have an article posted on why they do so. So, technically, the motherboard has two USB 3.1 ports (one Type-A and one Type-C) that are being provided by the ASMedia ASM2142 controller, while the rest are USB 3.0 ports that are being provided by the Intel Z270 chipset.

ASRock Z270 Killer SLI Overview

Even though the retail price of the two motherboards is very similar, ASRock’s approach is significantly different than that of MSI’s. The ASRock Z270 Killer SLI is a motherboard trying to combine features with aesthetics. It features RGB lighting (chipset heatsink, plus a header for RGB LED strips) and has a painted PCB to identify with the Killer brand. It is almost identical to SLI’s offering in terms of drive support, featuring two M.2 PCIe 3.0 x4 slots with one of them supporting M.2 and a total of six SATA 6Gb/s connectors. The only difference here is that both M.2 slots support devices only up to 80 mm long. Similar to the MSI, both of the main PCIe slots from the CPU come with integrated slot guards to reduce any potential bending or warping from heavy graphics cards.

ASRock also went with the highly popular Intel I219-V Gigabit LAN chipset. To contrast, the audio chipset is the now aged Realtek ALC892, which is a mediocre choice for a gaming motherboard. The motherboard also has no support for USB 3.1 (10 Gbps) devices at all. The ASRock Z270 Killer SLI has one Type-C connector and five Type-A connectors, all of which are USB 3.0 (5 Gbps) compliant. Headers for two extra USB 3.0 connectors and up to five USB 2.0 connectors are available. There is also a header for Thunderbolt AIC connectors (5-pin or 10-pin), which cannot be found on the MSI Z270 SLI Plus.

    Nice article, more mainstream reviews are always appreciated.

    people need to realize that z270 and intel are still a great buy for regular users. its not a bad investment. i just prey that 6core comes in time to consumers.
  • ddriver - Monday, May 1, 2017 - link

    Aside from the fact it is highly unlikely it will accept more than a single generation of processors.
  • Cygni - Monday, May 1, 2017 - link

    Seems pretty likely that Coffee Lake is intended to be compatible with Z270.
  • ddriver - Monday, May 1, 2017 - link

    That would be a new one for intel ;) If that happens, I guess "competition". For years now, intel has been artificially limiting chipset compatibility to squeeze extra chipset sales by obstructing upgrades.

    Thats not what I've been reading....New Intel Coffee Lake 6 Core CPU's will need the 300 Series Chipset which means....New Motherboard !

    The Inter Coffee Lake 6 Core CPU's will need the 300 Series Chipsets which means...New Motherboard !

    Totally agree, more reviews of the volume pieces would benefit far more readers. I won't be buying either of these but at least now I know why.

    It's incredible that they can market something so complex, with so many precision parts, materials, and process steps - not to mention all the ICs - for a delivered price of $140! These are the benefits to us of mass production and sadly low foreign wages. Given that I'd use such a mobo heavily for hours every day, for years, I'd willingly pay more if I knew the workers got more.

    Nice write up Thank You. I just looked the MSI board up at Memory Express in Canada it goes for $209.99 CAD which sounds about right after exchange rate.
