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.

    There is an VERY IMPORTANT ERROR in this article about the Asus Z590 gaming series motherboards - one that has potentially just cost me a chunk of the £320 i paid for one!
    In the article above, it states that the Z590-F Gaming WiFi motherboard will run in either x16, x8/x8 or x8/x4/x4 modes. THIS IS WRONG! The board will actually only run x16 for PCIe slot 1, if you have a card in slot 2, it drops to x8/x4 not x8/x8. for me this is a complete deal breaker as I have an RTX3070 and an LSI SAS RAID card which runs at PCIex8 - and is now running at x4 :(

    Are there any Z590 mobos that do not have a PCIe switch between the socket and the gen4-capable slots?
    If not, what motherboard has the best throughput @ Gen4?
    Looking to plug in something like a Mellanox ConnectX-6DX which can do 1x200GbE / 2x100GbE, and want best possible bandwidth.

    Only one PCIe slot is 4th gen on all of these current motherboards. The other one or two M.2 slots are 3rd gen so you don't need to bother spending more money on your other NVMe storage devices.

    Regarding your z590 Vision D description:
    “ Finishing off the rear panel is a pair of Intel I225-V 2.5 GbE controllers, with Intel's latest AX210 Wi-Fi 6E CNVi, which also includes support for BT 5.2 devices.”

    The article is in need of a correction: this board comes with the AX200 chip, not the ax210.

    Yeww ... a PS/2 port? I didn't know we still live in the 90s. Every time I start shopping for desktop upgrade, my search gets halted when I see PS/2 ports, VGA port, HDMI port or USB 2.0 port - it just makes me want to puke. And what's up with the motherboards that have 5 different video outputs? Pick a standard and stick with it! If I need to switch connectors I will use an adapter.

    P.S. Can we for ONCE see a motherboard with a decent amount of PCIe slots(I would like to see mATX with two x16 and two x4, none of that useless x1), no old USB ports but only the latest USB-C(we know how to use USB adapters and hubs), same type of video output(preferably something that supports the latest video standards), and NO legacy ports !!! Oh and if possible at least 3 M.2 NVMe ports, to allow for a decent RAID.

    Ah crap, I forgot - and a dual 2.5Gb LAN please. Some of us can no longer have their workloads on legacy 1Gb connections.

    Does the Asus Prime Z590-A Motherboard have a Third-Party USB Controller? Gensys Logic? I have an Asus Prime Z590-A it has a Gensys Logic USB Controller. Why would they not use the Intel Z590 Chipset USB controller.
