GIGABYTE TRX40 Aorus Pro WIFI
Moving our way down the GIGABYTE TRX40 product stack, we have the GIGABYTE TRX40 Aorus Pro WIFI which represents its entry-level model at launch with a good feature set but drops some of the higher-end components to undoubtedly save users money who may not need or require things like 10 GbE. This doesn't mean the feature set isn't good quality as there is an Intel AX200 Wi-Fi 6 wireless interface, three PCIe 4.0 x4 M.2 slots, and support for DDR4-4400 memory across eight slots.
The GIGABYTE TRX40 Aorus Pro WIFI and TRX40 Master share a very similar aesthetic with black metallic heatsinks on an all-black PCB, although the GIGABYTE TRX40 Aorus Pro WIFI is using a standard ATX sized PCB. There are eight memory slots which support up to DDR4-4400 and up to 256 GB in total, with two sets of four slots flanking either side of the sTRX4 CPU socket. All three of GIGABYTE's launch day TRX40 boards are using the high-end Infineon XDPE132G5C 16-phase PWM controller operating at 12+2. The CPU section of the power delivery is a 14-phase design which consists of twelve Infineon TDA21472 70 A power stages for the CPU. Providing power to the CPU is an 8-pin and 6-pin pair of 12 V ATX CPU power inputs.
Cooling the TRX40 chipset is an actively cooled heatsink, while the boards three PCIe 4.0 x4 M.2 slots each include an M.2 heatshield. For users looking to use SATA drives, the GIGABYTE TRX40 Aorus Pro WIFI has eight SATA ports which support RAID 0, 1, and 10 arrays, and are controlled by the TRX40 chipset. Located around the board is eight 4-pin headers which are split into three main sections; one for a CPU fan, one for a water pump, and six for chassis fans. Utilizing as many of the PCIe lanes from the CPU are four full-length PCIe 4.0 slots which operate at x16/x8/x16+x8, with a single PCIe 4.0 x1 slot for good measure.
Unlike the other models in the GIGABYTE TRX40 product stack, the TRX40 Aorus Pro WIFI has a single Ethernet port controlled by an Intel Gigabit controller. For users looking for wireless support, GIGABYTE has included an Intel AX200 Wi-Fi 6 wireless interface which also features BT 5.0 connectivity. Looking at USB support and there is five USB 3.1 G2 Type-A, one USB 3.1 G2 Type-C, and four USB 2.0 ports. Nestled on the left-hand side of the USB 3.1 G2 Type-C port is a small Q-Flash Plus button, while the five 3.5 mm audio jacks and S/PDIF optical output are powered by a pair of Realtek HD audio codecs; an ALC4050H and an ALC1220-VB.
The GIGABYTE TRX40 Aorus Pro WIFI isn't as high-end as its other launch day counterparts, but it still offers a cheaper alternative to users looking to utilize the high core count and power of the Threadripper 3000 processors with an MSRP of $399. Users looking to build a high-core high-thread-count gaming system will be hard pushed to find a better value TRX40 model at launch.

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.
