The ASRock Z270 Supercarrier Motherboard Review: 4-way SLI and 5 Gigabit Ethernet on Kaby Lakeby E. Fylladitakis on September 29, 2017 9:00 AM EST

Ever since Intel released the Z270 chipset earlier this year, we reviewed several motherboards based on it, ranging from the low-cost Mini ITX ECS Z270H4-I Durathon 2 to the advanced gaming motherboards from Asus and GIGABYTE. As literally dozens of Z270-based motherboards were released, we could not possibly review them all and we centered our choices on products that we believed to be of interest to the largest portion of our readers. However, someone could argue that even though the top-tier market is relatively small, it also consists of the most knowledgeable and demanding users, who cannot fulfill their wants and needs with a mainstream motherboard.
In this review, we are having a look at the ASRock Z270 Supercarrier, a top-tier motherboard designed for professional designers and elitist gamers. Despite its typical ATX dimensions, the Z270 Supercarrier is loaded to the hilt, with a tremendous number of connectors and several features that cannot be found on mainstream motherboards. While the price tag will drive every casual/mainstream user away instantly, the Z270 Supercarrier is one of the few choices with a LGA1151 CPU socket available for professional designers and gamers who are not satisfied with one or two GPUs.
The ASRock Z270 Supercarrier Overview
A simple glance at the list of this motherboard’s features is likely to leave most people in awe. If we were to single out the highlights of the Z270 Supercarrier, these would be the 14-phase CPU power circuitry, the four PCIe ×8 slots for full-size graphics cards and the AQUANTIA 5 Gbps network controller, all of which are features that cannot be found on mainstream motherboards. The number of supported storage devices is immense, with three PCIe ×4 M.2 slots, six SATA connectors and two SATA Express connectors. Each SATA connector may also be used as two standard SATA ports, bringing the maximum number of regular SATA devices up to 10 if no SATA Express devices are installed. There are no U.2 connectors and this is one of the very few features that the Z270 Supercarrier is lacking. This problem can be easily tackled with the use of proper M.2 to U.2 adapters.
The ASRock Z270 Supercarrier also has very interesting controllers installed. The “Purity Sound 4” onboard audio has a popular ALC1220 audio controller supplied by Realtek at its heart, supported by a Texas Instruments NE5532 headset amplifier and other hardware. It has not one, not two, but three different LAN controllers. The first is the Aquantia AQC108 5 Gbps controller, which is one of the highlights of this motherboard. Intel supplies the other two Gigabit controllers (I219V and I211AT), as well as the wireless LAN module (AC3160). We also found several controllers from ASMedia on the Z270 Supercarrier for additional USB, SATA, and Thunderbolt ports.
In summary, the ASRock Z270 Supercarrier is a motherboard primarily designed to entice professional designers, users who usually are seeking to build 3-way and 4-way SLI systems with a lot of storage devices. That is a very limited segment of the market and ASRock’s engineers are clearly trying to expand it by adding features that would also tempt gamers and overclockers with very large budgets. Even in its default configuration, the ASRock Z270 Supercarrier manages to outperform every other Z270-based motherboard that we have tested to this date, while it also displayed very promising overclocking capabilities during our testing. At this point we should mention that the higher overall performance does not come from any magic tricks but, as we found out during our testing, by ASRock’s engineers “cheating” and setting the CPU’s Turbo multiplier at 45 by default, allowing a 7700K processor to reach 4.5 GHz without tweaking any BIOS settings or other options.

Our Latest Best CPU Recommendations
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 do 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.
A Small Note on USB Naming
One thing that we should note is that the advent of the Z270 chipset brought a change on the naming of the USB ports. What we knew as USB 3.0 ports are now being dubbed as “USB 3.1 Gen 1” and the 10Gbps ports are now called “USB 3.1 Gen 2”. We first encountered this change while reviewing the MSI Z270 SLI Plus a few months ago but it seems that most of the manufacturers are following suit, rewriting their websites and reprinting their manuals. Users need to be extra careful when very high bandwidth connectors are essential.

Dr. Swag - Friday, September 29, 2017 - linkYou guys are reviewing so many z270 boards all of a sudden, but it feels a bit like a waste with z370 just around the corner, just saying.
shabby - Friday, September 29, 2017 - linkYa it's kinda funny how the z270 I'll suffer eof so quickly... classic intel.
shabby - Friday, September 29, 2017 - linkDerp eol
ddriver - Friday, September 29, 2017 - linkIt has 5 gbit lan... cuz the poor platform doesn't have enough lanes to drive more...
Timing is understandable, orders from intel hq came to push as much eol products as possible now, because pretty soon they will sell at a significant discount.
saratoga4 - Saturday, September 30, 2017 - linkDMI 3.0 is 32 GBit/s, so 5Gbit ethernet can easily go on the chipset PCIe switch. Which goes to show just how far behind everything else wired ethernet has fallen.
Wwhat - Thursday, October 5, 2017 - linkYou are right, the tech world really needs to massively go to higher because 1gb internet is all over the place now and they can't go higher because the average consumer would have issues plugging that into existing networking equipment.
I suppose they could include a modem with USB-C connector instead of LAN, but you can't assume every USB-C device actually has USB3.0 or higher speeds, sigh.
Plus many want their own router so it would be nice if routers on the market now were a bit forwards looking and did more than 1gbit.
And meanwhile LTE and such reach 1gbit when in fact data prices are such that Joe Average has no use for more than 50mbit or so.
The whole thing seems poorly thought out.
Notmyusualid - Sunday, October 8, 2017 - linkMore 'ddriver BS' - 5Gb/s LAN is seen as a cost-effective alternative to 10Gb/s NICs, that are still expensive to buy / implement.
There is tons more connectivity from the DMI than is required by all the NICs on this board - as stated by others.
Please seek professional psychological help.
SharpEars - Friday, September 29, 2017 - linkThat's right, I want to invest >$200 in a soon to be obsolete motherboard.
Gothmoth - Friday, September 29, 2017 - linkyou may not but anandtech likes to get all this intel money they spend on PR.
Morawka - Friday, September 29, 2017 - linkHey i just sold my z89 Asus Maximus VI Extreme motherboard on ebay for $300, it's not that far of a stretch. a man needs what a man needs.
