SuperMicro is a well known leader in server technology world wide, putting quality and reliability at the top of their list. This philosophy enabled SuperMicro to gain the respect of its customers, business partners and everyone inside the ICT industry. Now Supermicro entered the gaming motherboard territory a while back with the introduction of their Z87 motherboard. After generations of chipset technology, the company decided to brand their consumer products under SuperO – and thus the C7270-CG was born.

The Supermicro C7270-CG is an ATX gaming oriented motherboard that offers all the best of the Z270 chipset, backed with SuperMicro’s quality, and reliability. Noteworthy features included are the dual U.2 ports, the 15µ gold plated CPU socket, Intel LAN, the Texas Instruments powered audio solution, and the server-grade VRM power design. This thing also got dual M.2 ports for your consideration.



This green Z270 motherboard is loaded with features and connectivity out of the box, and if you wish to learn more check out its official product page.

Intel Z270 Platform

The Intel 200 Series Platform, specifically the Intel Z270 chipset is all about connectivity. While it isn’t much different compared to the Z170, it features an upgraded Intel Rapid Storage Technology (IRST) version 15, native support for the Intel Optane Technology, and Four additional downstream PCI-E 3.0 lanes compared to the last generation. Those down stream lanes could be configured by the board partner to either support additional storage, audio, or even networking options.


The platform is the official chipset for the Kaby Lake CPUs, but it will still support the Sky Lake CPUs. That said, system builders who are still using Windows 7 and the 6th Generation Intel CPUs wanting to go with the latest platform are not required to upgrade to the latest OS Microsoft has to offer. That’s right, Kaby Lake will officially end Intel’s support for Microsoft’s Windows 7 OS.

Intel Kaby Lake Processors

The Intel Kaby Lake Family of processors is the 9th generation of Intel’s Core Series CPUs. The Kaby Lake Family is practically identical to the Sky Lake architecture wise with small underlying differences. It is still based on the 14nm node, has the same Instructions Per Clock, and is just basically a repacked Sky Lake.


Now the differences, while not astounding are just proper for Intel to refresh their annual product line-up. Intel is able to put a 12% maximum performance gain via an improved design process, which basically means that they are able to push higher frequency envelope without touching the TDP. The Intel Core i5 7600K for example, features a 91W TDP with a 3.8GHz Base Clock and a 4.2GHz Turbo Clock. That is 300 MHz higher over the Core i5 6600K’s base and turbo.

Another thing worth noting is the updated Intel Speed Shift technology. It allows the Kaby lake CPUs to jump at Turbo Clocks faster than older generations. That, together with a new video decode unit, the Intel HD 630 IGP, is why Intel is marketing the Kaby Lake as a 14nm+ micro-architecture. The “+” is just too important for them to state that this is indeed a flushed 14nm package.


The SuperMicro C7Z270-CG comes in a rather unique packaging with a sliding color box, and a hard matte-black packaging. This is a premium looking presentation that I haven’t seen so far utilized on motherboards. Features and specifications are well laid out at the back.

Inside, you’ll find a manual, a software DVD, the back panel I/O shield, and a few accessories sealed inside an air tight plastic. These accessories are 4x SATA III cables, and a flex SLI bridge that is able to reach even the 4th PCI-E slot. There’s also a medium sized pack of silica gel to keep the moisture checked.

The SuperMicro C7270-CG is a full ATX motherboard that bleeds with green themed design. It certainly is a nice contrast over the other Z270 motherboards released so far. As for cooling, the board features L-shaped heat-spreaders for the VRM, and a huge PCH heatsink that lights up – providing accent to the huge SuperO logo. There are 5 PWM fan headers located at the board and they are more than enough for most gamer’s needs. Although I may like how it looks, SuperMicro will have a tough time penetrating the rest of the market with this board’s aesthetics. Gamers do love green, but an edgier design similar to their Z170 boards would fit better.

The board features a marketed 10+1 phase digital power design. It features VITEC’s PR72-151 which is a high frequency power inductor. These chokes are rated with operating temperature ranges of -40°C – 125°C which is rather pleasing indeed. The CPU socket features 15µ gold plated pin-outs by the way. This means that it wont rust under normal conditions. Virtually no oxidation should occur with this feature.

Going down and below allows us to check out the PCI-E area of the board. We’ve got Three full sized PCI-E slots here configured at x16, x16, and x16 electrically as long as you’ll use just one at a time. There are Three more PCI-E slots in a x1 package. The full size PCI-E slots are configured in 16+0+0, 8+8+0, and 8+8+4 respectively. You can see one of the M.2 slots here that also supports NVMe devices and RAID 1/0 configs.

Bottom end headers from left to right are as follows: HD Audio, 3x USB 2.0 headers, 1x USB 3.0 header, TPM, the front panel header, and another USB 2.0 header. There are lots and lots of extra jumpers we skipped here that you shouldn’t be concerned with – just yet. Most of them are for BIOS recovery, clear CMOS, and to electrically disable stuffs such as the audio. Pretty neat actually.

Now the back panel features 2x USB 3.0 ports, a DVI+HDMI+DP combo, and a USB 3.1 Type C & A port. Network connectivity is provided by a single Gigabit LAN port featuring the Intel I219V. Audio is provided by a Realtek ALC1150. A combo PS/2 port is also situated here as well.

Supermicro C7Z270-CG Motherboard (5)

Overall, the SuperMicro C7Z270-CG is a nice board full to the brim with connectivity options out of the box. We love the addition of U.2 ports, the 5 PWM fan headers, and the inclusion of Debug LED + onboard buttons.


SuperMicro goes with an allegedly simple looking UEFI but it is not as simple as it looks. To be honest, this is far from the best interface that I have used so far. It feels cramped, and I think I could design better. Mouse and keyboard navigation are too rough for my liking – adding insult to the injury. That said, it is still usable. Rather deep too, but it’s not just friendly by any means.

Supermicro C7Z270 UEFI BIOS (2)

There are 6 main menus to navigate, but you’re most likely going to dive into the CPU, and memory menus. The CPU menu features more sub menus and one of them pertains to overclocking. Here you can adjust your CPU’s ratio, voltages, and even load SuperMicro’s OC presets. Boot frequency can be adjusted too so you can enter the BIOS with a stable clock setting.

The memory menu is where you could overclock your memory kits, as well as to disable the banks that you do not require – or perhaps, disable for single channel config. A feature that is particulalry useful for overclockers. You can set your customs timings here too. Lots of options to be honest.

Supermicro C7Z270 UEFI BIOS (8)

The advanced mode is where you could tinker with your chipset and connectivity options. The onboard GPU can be configured here as well – with overclocking options too.

Supermicro C7Z270 UEFI BIOS (6)

Overall, the C7Z270-CG’s UEFI is full of options and settings to play with but is hampered by the cramped design and a not so user friendly navigation. We hope that SuperMicro could fine tune this UEFI in the near future to better suit most user’s appetite.


As if the UEFI isn’t enough, SuperMicro’s softwares are not best represented either – featuring a somewhat old school interface. These are functional, but the installer’s interface isn’t the best. There are minimal SuperMicro exclusive features thrown in too such as the Super Doctor 5.


For a gaming oriented motherboard, I expected even a single gaming software included.

Test Setup

The motherboard’s performance will be evaluated by various benchmarking tools, and applications with the CPU, memory, storage, and audio performance being the focus of the tests. We are testing this motherboard with the high performance settings enabled at the OS, with the default UEFI configuration, and XMP enabled if possible. No extra softwares or applications are installed and running during the benchmarking process. The test system specifications are laid out below:


Unfortunately, our Crucial Ballistix Tactical 2666 MHz is not fully compatible with this board yet. We can run it at JEDEC specifications of 2400 MHz, but it cannot boot with its XMP profile enabled nor have it set manually. Thus, we decided to go with the G.SKILL TRIDENT Z 3200 MHz kit. That said, this board could feature a better overall performance compared to the other boards tested.


Please do note that we are in the process of rebuilding our motherboard benchmark database. The charts that you will see here will be updated from time to time.


The AIDA64 Extreme Edition’s System Stability Test is used to stress the system to gauge its overall power draw. We selected all the the stability test options available with a 15 minute run time. Sleep (S3) and soft-off (S5) states are also tested.



Thermal results of the VRM and the PCH are also monitored during those tests. Do note that this represents the VRM and PCH’s heat-sink temperature during idle and at load.



The Intel Core i5 7600K follows a familiar overclocking procedure with the Sky Lake CPUs. With that said, a little nudge over the core voltage at 1.150v and the CPU’s multiplier at x44 are enough to bring this CPU at 4.4 GHz. This board featured better voltage control over the Extreme4 we tested a while ago. That one required us 1.248v to get a stable 4.4GHz.


We did go as far as 4.8 GHz with a vCore at 1.328v. This is a little higher than the one we got from the ASRock board so I guess our chip isn’t that good after all at higher frequencies.

The C7Z270-CG might be using an older audio solution from Realtek but it is no slouch when it comes to audio performance. Using high quality Japanese audio capacitors, and well isolated audio paths did payed off well for SuperMicro.


The C7Z270-CG is rock solid board from SuperMicro. Made to clad the latest Intel Kaby Lake Processors, this iteration of the Z270 platform is full on with features that you would expect from Intel’s top consumer chipset of the generation, with extra connectivity options to boot. That includes the RAID 1/0 compatible U.2 slots for blazing fast storage, and the dual M.2 solutions onboard.

Performance is good but even with a 3200 MHz kit onboard, our ASRock Extreme4 still manages to win on some benchmarks. That being said, it could be just the memory kits having little to no effect on some of the benchmark suites we tested or perhaps it is the board itself. Anyway, you’re still getting a proper performance margin with this board out of the box. Just don’t expect miracles.

Build quality is top notch, with a server grade VRM and a thick PCB to start with. SuperMicro markets this motherboard with server quality control so there’s that for your convenience. Overclocking is no slouch either, able to hit 4.8 GHz with ease.

As for hardware specific features, you’ll get a great audio solution, solid connectivity options, 5 PWM fan headers and a whole lot more. Software on the other hand is lacking – with basically nothing included that the gamers could utilize. The UEFI’s not so friendly interface is also something to consider. We do hope the SuperMicro could address these issues in the near future.

Pricing for the SuperMicro C7Z270-CG has yet to surface locally, but you can have this for 240 USD which should be equivalent to around 11, 000 Pesos. That’s a stiff competition for SuperMicro, where established brands have already flooded the market. Without a good bundle of software to back it up, it’s not easy to recommend this board. But, if all you need is a robust, and a functional board built with server quality in mind, then look no further. The SuperMicro C7Z270-CG is one rock solid motherboard that you should consider.

Update: Local pricing is set to 15, 290 PHP
