SuperMicro C7Z370-CG-IW Mini-ITX Motherboard Review

SuperMicro C7Z370-CG-IW

With an impeccable history of creating many of the most trusted and reliable motherboards in the world, we’ve been super excited to check out the C7Z370-CG-IW from SuperMicro. Forget crazy fins and aesthetics, tacked on RGB lighting, and funky graphics, because that’s not the SuperMicro way. Function over form, and reliability and round the clock performance are what matter here. If you want great gaming performance without all the gimmicks, SuperMicro wants your attention here.


It may lack gimmicks, but it’s packing plenty of goodies to keep you sweet. Equipped with support for high-speed DDR4 memory, robust connectivity, dual M.2 mounts, Optane support, and more. I’m really happy to see good Wi-Fi onboard, as well as the properly fantastic ALC1220 chipset for audio.

What SuperMicro Had to Say

“SUPERO’s Core Gaming series does away with the nonsensical features, and focuses purely on the essentials for professionals, gamers, or anyone who seeks a solid, well-rounded board. By utilizing resources to better develop platform features instead of gimmicks, the Core Gaming series offers excellent performance matched with uncompromised reliability.” – SuperMicro

“SUPERO has made its very first mini-ITX form factor motherboard loaded with features that all gamers and enthusiasts would enjoy in a small, portable package. This beast of a motherboard lets you build the most extreme gaming system anywhere with its vast connectivity options and has the power to take on any computing task with Intel’s latest 8th generation Core processors! Don’t forget the customizable RGB LED options you have for this board so you can light up your system to get that flare from the inside out.” – SuperMicro


A Closer Look

For a no gimmicks motherboard, it’s hardly lacking in design. Straight away you can see a tidy looking black PCB that’s sure to compliment any system build.

All the primary hardware is black, so it blends in nicely. However, there’s some reassuring looking armour on the DIM slots, ensuring the motherboard doesn’t flex.

Connectivity is pretty decent, with all the usual headers. There are only two fan headers, but that’s not uncommon for a mini-ITX motherboard.

The CPU takes its power from an 8-pin header, so more than enough any 8th Gen CPU. The power runs through their digital PWMs, with Dr. MOS, and ferrite chokes, ensuring 24/7 reliability.

The first M.2 mount it tucked just above the PCIe 16x slot, and a clever heatsink design should help ensure good performance for the drive, as well as the motherboard chipsets.

More armour on the motherboard for the PCIe slot. With modern GPUs being big and heavy, it’s good to see this motherboard is prepared to take the strain.

Towards the back, a chunky lump of metal to keep the VRM cool, with the Wi-Fi card tucked in behind it.

The rear I/O is pretty straightforward. Of course, you’ll find plenty of USB ports, the audio jacks, and WiFi. I’m happy to see dual display outputs too, with both HDMI and DP on offer for SFF systems.

Finally, on the reverse side, you’ll find yet another M.2 drive mount, giving us two in total. Of course, that’s perfect for those using NVMe storage, and an Optane drive for optimal performance.

Testing and Methodology

Test Procedure

Here at eTeknix, we endeavour to disclose vital information regarding the benchmarking process so that readers can quantify the results and attempt to replicate them using their hardware. When it comes to motherboard reviews, the benchmarks are pretty self-explanatory although there are a few exceptions.

Rember that your choice of motherboard, the silicon lottery, and other factors can yield different numbers, and there’s always a margin for error when using the software. Therefore, your experience may vary. Each benchmark runs three times, and the average figure is taken to try to reduce the effect of hardware variation. Of course, any relevant details regarding the parameters will be listed below.

Test Systems




AM4 Ryzen R3, R5 and R7



Games Used

All games are tested on a 60 Hz display with V-Sync off for all tests. Previously we would use “extreme” presets, but these have now been adjusted to “Medium” or equivalent to better test the capabilities of the CPU, not the GPU.

Software Used


To stress processors to their absolute limit and accurately judge their performance in video editing workloads, we transcode a 7.7GB compilation of gaming footage; this particular file is freely available from here. The captured footage is 22 minutes and 12 seconds long, it has a bit rate of 50.1 Mbps and it uses the Advanced Video Codec. Additionally, the video runs at a constant 30 frames-per-second and opts for a 3820 x 2140 (4K) resolution. Once loaded into Handbrake, we then transcode the 4K MP4 to an MKV file using the “normal” profile.

Other Notes

A rest period of 2-5 minutes is observed between each piece of software allowing the system to return to its idle power usage and temperatures. Background services like Windows Update are checked to not be running during the testing period by setting WiFi to Metered Connection.


Thank you to NoctuaCrucialASUSGigabyteLian-Libe quiet!OCZ, for providing the hardware that helps makes these tests possible!

Synthetic Benchmarks

3DMark Firestrike

A mini-ITX motherboard this may be, but the performance is anything but mini. Straight away, it scored our 5th fastest score for 3DMark Fire Strike, so it can certainly keep up with the big boys. It lost a few places while overclocking but still remained competitive with the high-end motherboards by only a few points.



Unigine Superposition 1080p Extreme

PCIe throughput is easily tested with Unigine and at stock and overclocked, it’s right where it should be. The SuperMicro scored a respectable 5553 at stock, and 5519 while overclocked.



PCMark 10 Express

It seems like the latest from SuperMicro is on a winning streak. It scored strong again, with 6224 at stock, but pushed up to a fantastic 6584 points once overclocked; a great score for any Z370 motherboard.



WPrime 32M and 1024M

The 8th Gen CPUs aren’t the fastest for WPrime, but the SuperMicro motherboard delivered a very competitive score of just 107.843 seconds, and down to 101.540 once overclocked.



Cinebench R15

Again not an amazing score for Cinebench, but still very competitive for Z370 and the SuperMicro motherboard is doing a fantastic job competing with everything else.



Handbrake MP4 to MKV Conversion 4K

For video transcoding, we hit 59.5 FPS at stock and 60.3 once overclocked. It’s great to see this motherboard doesn’t falter under the more demanding workloads.



AIDA 64 Memory Bandwidth and Latency

The memory performance pulled no surprises either, delivering read, write, and copy speeds that are right on track with what we would expect from this chipset. The memory latency performance was superb as well, right where we would have expected it to be.

Gaming Performance

OK, now it’s time to get on to the good stuff, as this motherboard does make a few promises for the gaming market. Straight away, we can see that it’s no slouch, delivering a very competitive 139.2 FPS in Deus Ex, and 199.7 FPS in Rise of the Tomb Raider for our DX12 benchmarks. Moving on from there, it delivered 140.8 FPS and 159 FPS in Ghost Recon and Far Cry: Primal respectively. They’re pretty high scores for any Z370 motherboard, and even better given it’s a mini-ITX motherboard.

Final Thoughts


Unfortunately, we couldn’t find retail stock of the motherboard at the time of writing. Of course, it has just launched this month, and sometimes these things take a few weeks to find their way into the market. Please check with your local retailers for up to date information.


There hasn’t been a single Z370 motherboard that has left me feeling disappointed. Which is surprising, as with most of them basically being Z270 motherboards with a slightly revised CPU pin layout, they didn’t seem that exciting to begin with. However, the new 6-core CPUs are knocking down previous benchmark records left, right, and centre. When it comes to getting great gaming performance, they’re the best around right now, so it’s hard to be too mad about the whole thing.


Given it’s one of the less exciting motherboards on the market, the SuperMicro Mini-ITX didn’t really give me much faith for its performance. However, you shouldn’t judge a book by its cover, as this motherboard managed to set benchmarks well into the high-end of our charts, and gave many more expensive boards a heck of a run for their money too. Mini it may be, but it performed as well as many ATX motherboards, which is fantastic.


It’s marketed as a no gimmick design, and that’s mostly true. However, it still looks neat and tidy and with a bit of armour, a black PCB and some sneaky RGB lighting on the rear right edge, it’s hardly a drab bit of kit. At least you’re not overpaying for a more outlandish design. However, with SuperMicro favouring reliability over much else, I have absolute confidence in this motherboards 24/7 operation capabilities too. Function over form is no bad thing.

Should I Buy One

If you’re looking for a powerful and fast motherboard in a mini-ITX form factor, it’s as good or better than anything else out there. ASUS and Gigabyte all have some competitive options, but likely at a higher price point, so it’s nice to have more options on the market, especially from SuperMicro, who have such a strong reputation for build quality.
