Supermicro just launched four Z390 motherboards that are available to purchase as of today, with the fully loaded C9Z390-PGW leading the pack.
The mini-ITX C9Z390-CG-IW, the ATX C9Z390-CG, the loaded ATX C9Z390-CGW, and the fully loaded ATX C9Z390-PGW for those who want the most feature loaded Z390 we have yet to see. The high-end C9Z390-PGW features the iconic PEX8747, which is now sold by Broadcom and can increase PCI-E lane count from the CPU by 100%.
We get a total of 32 PCI-E 3.0 lanes attached to the chip, which is then attached to the CPU, and this will let you run two cards at x16/x16 or all slots at x8/x8/x8/x8 among other configurations. Supermicro has also revamped their UEFI BIOS, and they offer their SuperO Booster application that allows for simple and easy to use Windows based overclocking, fan control, and RGB LED control.
On top of that, the motherboard features a 10Gbit LAN controller, an Intel 1Gbit LAN controller, and integrated Intel AC 9560 WIFI/BT rated up to 1.733Gbps on the 160MHz channel. Power delivery is top notch with a digital PWM controller from Primarion, Infineon TDA21232 50A integrated power stages, and VITEC high current inductors. On the storage side of things we get two M.2 slots and two U.2 slots, with full support for the latest Optane drives.
Both M.2 slots have large heat sinks on them. Audio has also been upgraded, with an added amplifier for the front panel headphone output. The new Intel Z390 chipset offers a lot of USB 3.1 Gen 2 (10Gbps), and Supermicro has four USB 3.1 Gen 2 ports on the rear IO panel as well as a type-C USB 3.1 Gen 2 internal header. The WIFI M.2 slot also has full CNVi support for easy Intel PHY WIFI upgrades down the line. The sleek gun-metal construction of the heat sinks is complimented with a few integrated RGB LEDs, two RGB LED headers, and black color polymer capacitors. The C9Z390-PGW can be purchased today for $335.
