Supermicro C9Z590-CGW & C9Z590-CG

Supermicro is more commonly known for its workstation and server boards, but it does cater to the desktop market too with its SuperO series. It intends to release two ATX models for Z590, the C9Z590-CGW and C9Z590-CG, with the only difference is that the CGW model includes Wi-Fi 6. The design omits any form of RGB LED lighting and instead focuses on the essentials. Both models include a mixture of black, dark gray, and silver aesthetics on the rear panel cover and chipset heatsink, with solid black power delivery heatsinks keeping the VRMs cool.

Both models include two full-length PCIe 4.0 slots, which run at x16, and x8/x8, with two PCIe 3.0 x1 slots. Memory support allows up to DDR4-4000, with up to 128 GB of capacity across four available memory slots. For storage, Supermicro includes three M.2 slots, including one PCIe 4.0 x4 and two PCIe 3.0 x4 slots, with four SATA ports capable of support RAID 0, 1, 5, and 10 arrays. The C9Z590-CGW and C9Z590-CG include a USB 3.2 G2x2 Type-C header, with one USB 3.2 G1 Type-A header (two ports), and one USB 2.0 headers (two ports). For cooling, Supermicro includes five 4-pin fan headers and a single DOM PW connector.

On the rear panel of the Supermicro C9Z590-CGW, it has two ports for the Wi-Fi 6 antenna, which is the only thing the CZ590-CG doesn't include. The rest of the panel is shared between both models, including two USB 3.2x2 Type-C, two USB 3.2 G1 Type-A, and four USB 2.0 ports. Supermicro typical installs premium networking, and both models feature an Aquantia AQC113C 10 GbE and Intel I219-V Gigabit controller pairing. The rest of the panel includes two video outputs, including HDMI 2.0a and DisplayPort 1.4, with five 3.5 mm audio jacks and S/PDIF optical output powered by a Realtek ALC1220 HD audio codec.

Supermicro hasn't shared any information on pricing with us so far.

    I'm a bit surprised they went to an x8 3.0 link on the chipset instead of an x4 4.0 one, even if everything coming off of the chipset is still limited to 3.0 speed. Reply

    Might be because it makes routing the traces easier, they don't have to adhere to the PCIe 4.0 signal requirements. Downside would be that more pins are required. Reply

    Other being quite boring platform , there is noticeable lack of M-ATX offerings. Reply

    Also it seems like even with properly finned heatsinks Gigabyte Aorus master requires a fan to cool VRMs which is not a good sign. Reply
