ASUS Zenith Extreme
Unlike MSI and Gigabyte, ASUS has a kit for their existing X399 motherboard. The kit comes with a fan bracket, a fan and a SoC heatsink. The kit ensures that there shall be no problems with Ryzen Threadripper WX-series, even with overclocking.
At launch, Zenith was the most advanced motherboard on the market. The premium look and feel accompanied by premium price surely made every reviewer interested. The Zenith was one of the first motherboards to feature onboard OLED display, a technology, which might soon become a standard feature of high-end motherboards.

GIGABYTE X399 Aorus Extreme
This is the highest-end Gigabyte motherboard ever made. It comes with eight reinforced memory slots, four PCI Express x16 slots, three M.2 connectors (each with a separate heat spreader), three Ethernet connections (one of which is 10Gb) and even a full cover backplate. The CPU is fed by 10-phase VRM coming from a pair of 8-pin EPS and 6-pin PEG connectors.
This super high-end motherboard will be available on August 8th for around 500 USD.
MSI X399 Creation
A Ryzen Threadripper 2000 motherboard equipped with a tiny graphics card? No, that’s not a GPU. MSI’s X399 Creation comes with M.2 Xpander Aero. With the expansion card in use, X399 Creation will support up to 7 M.2 SSD devices at once.
The Creation features 16+3 phase design. The power is fed by dual 8-pin EPS connectors, which should theoretically offer up to 720W of power, but of course, so much power is not required, as this motherboard is designed for 250W CPUs.
MSI’s X399 Creation is clearly a motherboard for content creators. With 8 SATA,15 USB 3.1 ports, four PCIe x16 slots, we are looking at a very expandable motherboard, which has everything except a 10Gb LAN port.
