ASUS ROG Zenith II Extreme
Moving onto what ASUS has up its sleeve, and it has gone with a trio of new motherboards with each designed for a different target market. The first of the three is the ASUS ROG Zenith II Extreme which is the premier model on TRX40 for the company. Following on from its ROG Zenith Extreme X399 model, the new ROG Zenith II Extreme for TRX40 builds upon it with an aluminium heatsink cover surrounding the PCIe 4.0 slots, an aluminium rear panel cover, and a solid steel backplate on the rear of the board. Some of the main features included are the LiveDash color OLED 1.77" screen integrated into the rear panel cover, support for up to five PCIe 4.0 x4 M.2 drives, a Wi-Fi 6 wireless interface, and an Aquantia 10 GbE controller.
The ASUS ROG Zenith II Extreme is an E-ATX model which sits at the top of the ASUS TRX40 product stack. Its design is very interesting with lashings of aluminium via the rear panel cover, the armor covering the PCIe slot area, and the actively cooled TRX40 chipset heatsink. The rear panel cover has an integrated LiveDash color OLED screen which measures in at 1.77", and can be customized with the LiveDash software in the included software suite. There is integrated RGB LEDs too which are located within the rear panel cover, the chipset heatsink, and on the underside of the right-hand side of the board. A total of four full-length PCIe 4.0 slots which operate at x16/x8/x16+x8, and is accompanied by two PCIe 4.0 x4 M.2 slots on the front of the board, one PCIe 4.0 x4 M.2 slot on the rear, and an additional two PCIe 4.0 x4 M.2 available through the ROG DIMM.2 module within the accessories bundle. There are also eight SATA ports with four controlled by the chipset, and four from a pair of ASMedia SATA controllers; only the four SATA ports from the TRX40 chipset support RAID 0, 1, and 10 arrays.
On the power delivery, ASUS is using a similar design to its X570 models with a 16-phase design with 16 Infineon TDA21472 70 A power stages operating in teamed mode. The large aluminium power delivery heatsink has two small Delta Superflo fans to aid cooling, which the finned heatsinks are designed to optimize surface area with low resistance for airflow. Providing power to the CPU is three inputs which consist of two 8-pin 12 V ATX, and one 6-pin 12 V ATX power connector. Cooling support is extensive with seven 4-pin headers which are split into two for CPU fans, two for water pumps, one for a high-amp fan, and two for standard chassis fans. The board also has an LN2 mode jumper for extreme overclockers, a safe boot button, an OC retry button, a dual BIOS selector switch, and power/reset buttons.
On the rear panel of the ROG Zenith II Extreme is five USB 3.1 G2 Type-A, one USB 3.1 G2 Type-C, four USB 3.1 G1 Type-A, and one USB 3.2 G2 Type-C 20 Gbps port. Networking support is strong with an Aquantia AQC107 10 GbE controller, and a second port powered by Intel I211-AT Gigabit controller. The Wi-Fi comes from an Intel AX200 Wi-Fi 6 wireless interface, and also adds BT 5.0 connectivity for users. On the left-hand side are a BIOS Flashback button and a clear CMOS switch, while on the other side is five 3.5 mm audio jacks and S/PDIF optical output which is powered by a SupremeFX S1220 HD audio codec; this includes an ESS Sabre ESS9018Q2C DAC.
The ASUS ROG Zenith II Extreme has an MSRP of $850 at launch and sits as one of the most expensive TRX40 models, yet one of the most premium. One of the primary benefits is that enthusiasts and power users can use up to five PCIe 4.0 x4 M.2 drives as the ROG DIMM.2 slot makes itself a prominent feature on ASUS's high-end models. There is a lot of enthusiast-level features with a lot going on for extreme overclockers including ASUS's teamed 16-phase power delivery for the CPU, with added LN2 mode and an overclocker's toolkit.

Although the Designare TRX40 is the only Gigabyte mobo that supports TB3 out of the box, I noticed the Auros WiFi has a THB-C port, same as the designare which uses to connect to the titan ridge. Does anybody know of the titan ridge card works with the Auros WiFi as well?PopinFRESH007 - Sunday, December 29, 2019 - link
REF: Page 4 ASRock TRX40 Taichi, last paragraph, first sentence"The ASRock TRX40 Taichi is the premier board for enthusiasts in its line-up with each of the four full-length PCIe 4.0 slots supporting x16 across the board"
The ASRock TRX40 Taichi only has three (3) full-length x16 slots.

@gavbon could you check if you guys have access to a block diagram for the ASRock TRX40 Taichi? Now that the CPUs are slowly becoming available and should be in-stock shortly I've been considering this board to upgrade. My use case is for 2x 2080Ti NVLINK with an Quad x4 NVMe SSD AIB so the Taichi is one of the only boards that can actually support this with its PCIe slot configuration.I also have 2x U.2 NVMe SSDs and I'm trying to figure out if the two on-board M.2 KeyM sockets are coming from the CPU or the chipset and the ASRock manual doesn't include a block diagram.

has anyone had an issue with the XL size of this trx40 Designare board fitting into atx cases. There doesn't seem to be to many out there and they are all terribly bland or built for custom loops. I plan to use a aio and would love to put it all in a Lancool 2 when they ship later this month. Any Case recommendations here?PopinFRESH007 - Saturday, January 18, 2020 - link
There will definitely be compatibility issues with the length of it. Most cases designed for E-ATX should be ok for the width. I have an Enthoo Evolv X case that I would absolutely recommend, however, the TRX40 Designare board definitely wouldn't fit as I have an SSI-CEB spec'd board and it is a sliver away from the bottom case shroud. Based on the dimensions and spec of the Lancool 2 I'd say you'd have the same issue with the TRX40 Designare fitting in that case, e.g. it won't "vertically" fit. Something like the older HAF-X case would fit itaCuria - Thursday, January 30, 2020 - link
There is an error: "ASRock TRX40 Taichi ... four full-length PCIe 4.0 slots"... This board only has 3 full length PCIe 4.0 slots, not 4jangray - Friday, February 14, 2020 - link
Will any of these TRX40 motherboards permit bifurcation of one of the gen4x16 slots into gen4 x8x8? Based on current motherboard users guides, some allow gen4x16 -> gen4 x4x4x4x4 but none seem to do gen4 x8x8 (unlike the Aorus X570 for example). Thanks for any pointers.
