First of all, the SuperO C9Z490-PGW and the C9Z490-PG are virtually the same models with the only difference being that the PGW features WiFi 6 support whereas the PG model doesn't feature WiFi 6 capabilities. So with the differences out of the way, let's take a look at what SuperO has to offer.


The SuperO C9Z490-PGW motherboard features an 8+4 pin power connector for the CPU socket that is powered by a high-end VRM. The exact VRM phases are not mentioned for these boards but it fully supports overclocking with Intel's flagship Core i9-10900K and other unlocked chips. There are four DDR4 DIMM slots that can support up to 128 GB memory capacities with speeds of up to 4000 MHz (OC+). The VRMs are cooled by two sets of aluminum heatsinks which feature black color finish. The DDR4 memory slots feature metal shielding and we can also spot a series of overclocker friendly power buttons such as Power/Reset/Memory test.

Storage on the two Z490 motherboards comes in the form of 4 SATA III ports. Expansion slots include four PCIe 3.0 x16, a single PCIe 3.0 x1, and two M.2 slots. Both M.2 slots feature heatsinks and come with pre-applied thermal pads for storage devices to run cool.

There's a third heatsink right below the CPU socket which cools the PLX (Broadcom PEX8748) chip. With this chip, the motherboard can run the PCIe 3.0 x16 slots at x16/x16 mode or x8/x8/x8/x8 mode. This is particularly interesting for the content creator and workstation builders who can use the motherboard to add in several AMD Radeon WX or NVIDIA Quadro graphics cards on this board.

SuperO C9Z490-PGW & C9Z490-PG Z490 Motherboards:


I/O on the motherboard include an Aquantia 10Gbe and an Intel 1Gbe LAN port. There's also 1 USB 3.2 Gen 2x2, 4 USB 3.2 Gen 2x1, 4 USB 3.2 Gen 1 ports on the motherboard. Other I/O includes WiFi 6 (Bluetooth 5.0) for the PGW model, 1 HDMI 2.0a, 1 DP 1.2, Realtek ALC1220 powered 7.1 channel HD audio jack & BIOS switch on the rear panel. The SuperO C9Z490-PGW will retail at $395 US while the C9Z490-PG will retail at $375 US. Expect SuperO Z490 motherboards to hit retail on the 20th of May.
