With our build guide pairing the SuperO Z590 C9Z590-CGW with the Intel Core i5 11600K out in the wild, we step back to take a closer look at the board at the heart of the build. The C9Z590-CGW is the latest board from SuperO, a subsidiary of Supermicro focused on designing high-quality "gaming" motherboards with decades of experience in the server market.

The SuperO C9Z590-CGW is one of two SKUs available for purchase with the Z590 chipset; the other, the C9Z590-CG, would omit the W in the model and come without WiFi6 and BT 5.1. That said, both SKUs are stacked with connectivity, including 5, 10, and 20Gb/s USB 3.2 on the rear I/O and 10Gbe from the Marvell AQC113C chipset.

Running through the platform specifications, this board does support 11th Gen Intel Rocket Lake CPUs, with RAM support for JEDEC 2133-3200MHz and XMP up to 4000MHz. The maximum memory capacity is 128GB with 32GB DIMMs.

Storage support includes four SATA3 ports, 2x Ultra M.2 slots, and one Hyper M.2 slot.

Pricing

The SuperO C9Z590-CGW carries an MSRP of $379.99 with a three-year warranty.

Cinebench, Realbench and AIDA64

Cinebench R23

Cinebench is a long-standing render benchmark that has been heavily relied upon by both Intel and AMD to showcase their newest platforms during unveils. The benchmark has two tests, a single-core workload that will utilize one thread or 1T. There is also a multi-threaded test that uses all threads or nT of a tested CPU.

Getting in closer to the VRM, we do see a 36c peak temp near the rear I/O.

Final Thoughts

The Supermicro SuperO C9Z590-CGW is a refreshing platform that focuses on reliability and functionality while offering one of the most feature-packed motherboards I have come across. While all Intel Z590 motherboards support USB 3.2 Gen 2x2, most vendors push it through an internal header. The SuperO is the first I've come across to push that connectivity through multiple ports on the rear I/O while offering a host of USB 2.0 for peripherals and standard USB 3.2 for high-speed flash drives and external backup solutions.

10Gbe might be one of the most significant selling features of this platform. The rest of the market focuses on 2.5Gbe as its staple and completing platforms offering 10Gbe, like the Z590 AORUS Xtreme retailing at $849 - Supermicro is doing it at half the cost. In testing, I found the SuperO to be a fantastic board with results on par or better than the average of our last five Intel Z590 boards tested and even more excelling in storage performance.

EFI for the SuperO Z590 is one of the most complete platforms I've seen, with a well laid out EZ Mode for novice users to set XMP settings or enable a preset profile for enhanced CPU performance. Further, the advanced menu system offers a plethora amount of overclocking options broken down into categories. In contrast, further menu options allow you to configure everything from the type of cooling solution you are using to connectivity, CPU and graphics configurations, and even motherboard power settings, to name a few.

Additionally, the SuperO C9Z590-CGW is a rare bird, offering no RGB functionality, something highly uncommon in the current market, making this motherboard a true gem for old-school purists that want a reliable gaming platform to build on from a very trusted motherboard maker.
