The same as all SUPERO motherboards, also the C9Z590-CGW is well-equipped. There are two LAN ports, WiFi 6, Bluetooth 5.1, multiple fast USB ports, and even a COM port.

On the motherboard is also a power and reset button, diagnostic LED display and multiple monitored fan connectors. There is everything that gamers may need, except maybe ARGB/RGB connectors which are common on gaming motherboards nowadays but we won’t find them on the C9Z590-CGW.

On the next page, I will show you product photos and will tell you some more about some motherboard components.

Product Photos

The C9Z590-CGW arrived in a retail package, which is a typical flat box that looks similar to the one from the previous SUPERO motherboard series. The box contains everything we may need for installation. Inside, we can find a manual, driver’s DVD, I/O shield, cable stickers, WiFi antennas, SATA data cables, and screws for M.2 SSD.

I like the professional looks of the motherboard. It doesn’t look like a toy and doesn’t have any weird logos in every possible place. On the other hand, it also lacks RGB or ARGB connectors what is already a standard on gaming motherboards. The SUPERO logo has a white backlight and besides that, we can see a red light from the diagnostic display on the bottom of the motherboard.

Power design is about the same as in the C9Z490-PGW motherboard so it contains 12 phases, which proved to be strong enough to handle a 7GHz processor. For daily work, we can count that 5.2GHz on the i9-11900K processor will be more than possible. We can only worry about the CPU cooling as these new chips are running really hot and it’s hard to set anything above 5GHz.

The C9Z590-CGW doesn’t have any fans but it still runs cool. Looks like Supermicro/SUPERO team made good work with the design. The same situation was with the previously reviewed SUPERO motherboard which as one of not many higher series motherboards didn’t have any active cooling because it didn’t have to.

Even while the CPU is loaded to the limits, then there are no electric noises called “coil whine”. It sometimes happens on cheaper motherboards or more often on graphics cards but not on SUPERO motherboards.

The C9Z590-CGW is a well-equipped motherboard. It contains everything that higher competitive motherboards have and also some more like 10Gb/s LAN which is available only on the most expensive motherboards.

The motherboard also supports three M.2 PCIe sockets. One of them is in PCIe 4.0 x4 standard while the next two are PCIe 3.0 x4. All M.2 sockets and SATA ports give us a chance to configure RAID 0/1/5/10 what is maybe less popular in the last few years but still, a good option.

The C9Z590-CGW has two PCIe 4.0 x16 slots which are perfect for new graphics cards. I won’t hide that I wish to see a larger space between these slots as a single slot space is problematic if we wish to use two, higher-performance graphics cards. All of the new graphics cards are at least two or more slot thick. For example, the Radeon RX6800XT graphics card used for tests takes nearly three slots of space.

I’m glad to see the 10Gb/s LAN controller on the motherboard. This time it’s Marvell AQC113C chip. Most motherboards for gamers have 2.5Gb/s LAN controllers which are somehow weird standard nowadays as on the market are widely available 5Gb/s switches and routers but also 10Gb/s devices are getting more popular. Even less expensive NAS like TerraMaster reviewed a couple of weeks ago, was equipped with the 10Gb/s port.

On the motherboard, we will also find multiple USB ports, including the latest 3.2 Gen 2 20Gb/s standard, audio and COM headers, and many more. As I mentioned earlier, everyone will find something interesting.

The CZ590-CGW has a diagnostic LED display and a set of power, reset, and clear CMOS buttons on the motherboard. This is again available only on the most expensive motherboards and overclocking series so I’m happy to see it.

On the next page, we will take a look at BIOS/UEFI.


BIOS/UEFI is a mix of well-known settings and options which we can find mostly on more advanced server motherboards. Actually, we won’t find so many options on most server motherboards. It works both ways. Enthusiasts and overclockers will find it really interesting as there are various options to tune the PC. On the other hand, less advanced users may feel lost as there are simply a lot of options, and some are pretty advanced.

To less advanced users or simply those who want to plug and play easily, I recommend EZ Mode. It’s the starting window of the BIOS/UEFI. We can find here everything to run our PC, set basic options, and enable XMP.

BIOS Update

unnamed file 922

Presented screenshots were taken from 1.0 BIOS/UEFI. It’s a stable version that doesn’t cause issues.

Performance: CPU and Memory

Tests were performed on the Intel Rocket Lake-S platform which contains the i7-11700K, 8-core processor, Ballistix MAX RGB 32GB DDR4-4000 memory kit, ASRock Radeon RX6800 XT Phantom Gaming OC graphics card, Crucial P5 500GB, and Silicon Power US70 1TB NVMe SSD, Patriot PXD 1TB USB 3.2 SSD, Abconcore 850W Gold 80+ PSU, and Enermax Liqmax III 360 AIO CPU cooler.

Let’s begin the tests.

The CPU is highly limited by the cooling but it’s hard to find any better cooler on the market unless we start to build our own, custom water loops. The CPU is running without issues at declared 5GHz on single cores and at up to 4.6GHz on all cores. Overclocking is highly limited as I already said, but we were able to stabilize our i7-11700K CPU at 4.9GHz on all cores. Just as a comparison, on previously reviewed ASRock Z590 Extreme, we could only reach 4.8GHz.

unnamed file 924

RAM works well up to DDR4-3600 at which it uses a 1:1 memory controller ratio. We are able to set anything higher but will work at a lower ratio so the performance will be also lower than expected. This is a new setting in the Rocket Lake processor series.

The performance is as high as expected. Below is our 32GB kit in AIDA64 Cache and Memory Benchmark.

unnamed file 925

More important seems performance in daily applications and this situation simulates PCMark 10. Our results are great for the PC specification so of course, we are happy to see so high scores.

unnamed file 926

On the next page, we will take a look at 3D benchmarks, which are the most important for gamers.

Performance: 3D Graphics

All 3D benchmarks from UL are showing us exceptional results. Considering that in use is the RX6800XT graphics card, I wouldn’t expect low scores. Our tests confirm that the performance in these benchmarks is high and the CZ590-CGW motherboard has no problems with stability.

unnamed file 928


Some more 3DMark benchmarks and PCI Express feature test which is showing over 21GB/s bandwidth.

unnamed file 931


There is also a set of VRMark results. All confirm there are no problems with performance in the VR environment.

unnamed file 934


Below there are some results at higher and lower screen resolutions in Final Fantasy XV, Superposition, Shadow of the Tomb Raider, and Assassin’s Creed: Valhalla.

unnamed file 936


No problems in all tests. All fast and smooth.

unnamed file 938


Assassin’s Creed Valhalla at 2560×1440 and maximum display settings.

unnamed file 939


Shadow of the Tomb Raider at 2560×1440 and high display settings.

unnamed file 941


Performance: Storage and Network

Let’s start with NVMe SSD in PCMark 10 Storage tests. The first result is showing the performance of the Crucial P5 500GB SSD which is using a PCIe 3.0 x4 bus, while the second one is Silicon Power US70 1TB SSD so a PCIe 4.0 x4 bus. Both drives are fast.

unnamed file 942

Below are some more storage tests but this time in CrystalDiskMark.

unnamed file 943

Above is Silicon Power US70 1TB and below is Crucial P5 500GB.

unnamed file 945

Here is also Patriot PXD 1TB USB 3.2 Gen2 SSD. USB results are about as high as they can be.

unnamed file 946


Now it’s time for a couple of network bandwidth results.

unnamed file 948

Above is WiFi 6 connection and bandwidth between two computers and a Netgear router. Walls are thick and we can still see up to 1.5Gb/s bandwidth.

Below is a wired connection which is using 10Gb/s Marvell LAN. The average bandwidth is around 5-6Gb/s while every now and then we can see up to about 9Gb/s. The connection is between two computers in a local network where background services and other devices may slightly lower the results. It’s still an exceptional result.

unnamed file 949

At the end, 1Gb/s Intel LAN so a standard connection with an average of around 750Mb/s.

unnamed file 951

The CZ590-CGW provides multiple fast connections and it’s one of its strongest sides. If you are searching for an affordable motherboard that you can use for gaming but also as a workstation then it’s the way to go. The SUPERO once again delivered a well-equipped and fully stable motherboard.

unnamed file 953

Conclusion and Verdict

SUPERO once again offers a product that is a bit unique, but well-designed and well-equipped motherboard. A mix of server and gaming features that gives us a fast and reliable motherboard, which can be used as a solid base for an exceptional PC build.

The motherboard offers us various connection options, dual LAN, WiFi 6, and Bluetooth 5.1. Everything is perfect and the connection is fast on every controller.

There were no problems with stability or performance during all our tests. The CPU overclocks well and even higher than on some other motherboards. However, I wish to see better compatibility with higher frequency memory kits. RAM is stable and for most users, DDR4-3600 is still more than enough but the competition offers much higher speeds.

Gamers may also want RGB and ARGB connectors which are not available on the CZ590-CGW. For me, it’s not an issue as I’m not a fan of flashy PC and I know that many users dislike RGB lighting too. It’s just a standard nowadays that gaming motherboards have these connectors onboard.

Again a kind reminder, we’ve received an early sample so we don’t have a retail price of the CZ590-CGW, and currently popular stores don’t have this motherboard available yet. It will be updated soon, and hopefully in a couple of days these motherboards will be available … you can count on it!
