TRX40 Motherboards For 3rd-Gen Threadripper (2021 Update)

AMD’s 3rd-generation Threadripper CPUs still offer the best value by far if you are building a high-end desktop (HEDT) system in 2021.

The closest Intel competitors such as the Xeon W-3175X top out at 28 cores, so AMD’s only real competitor at the moment is AMD itself in the form of its Threadripper Pro platform. However, the 3rd-gen 64-core/128-thread TR 3990X is only marginally bested by the significantly pricier Threadripper Pro 3995WX in common rendering tasks.

For owners of previous-gen Threadripper systems, the downside is that the 3000-series generation uses the sTRX4 socket, meaning that 3rd-gen chips can’t be dropped into X399 motherboards. In other words, you are going to need a TRX40 motherboard to pair with your TR3 CPU.

Here, we will take a look at the alternatives for different use cases and budgets.

Best Value Vs High-End TRX40 Motherboards

Although it may offer much better value than the alternatives, there is no such thing as a budget Threadripper 3 build. All boards are well above the specs of mainstream platforms such as X570 and B550 in terms of the I/O offered. Other than plenty of PCIe 4.0 lanes, you get native USB 3.1 Gen2 and, more importantly, support for up to 256 GB of quad-channel DDR4 RAM, regardless of your choice. Nevertheless, prices and feature sets differ a great deal.

Asus’ TRX40 Flagship: Asus ROG Zenith II Extreme Alpha

Asus has an excellent track record in the high-end motherboard segment. So, we’re comfortable starting off our roundup with the ROG Zenith II Extreme Alpha. This board features eight RAM slots (four channels, as all TRX40 boards), plus four PCIe x16 slots for multiple GPUs or other add-in cards. It also comes with no less than five M.2 PCIe 4.0-based storage slots, including two on a separate add-in card (included).

In terms of connectivity, you get an Aquantia ACQ-107 10G Ethernet port, plus another 1Gbps LAN port, Wi-Fi 6 (802.11ax), and Bluetooth 5. The 16-phase VRM should be up for the task of powering the 3rd-gen Threadrippers up to the Threadripper 3990X with 64 cores, 128 threads, and 280-watt TDP. Note that Zenith II Extreme Alpha is a more recent version of the Zenith II Extreme (without the “Alpha”). The main difference between the two is the Alpha’s improved VRM with 16 Infineon TDA21490 90 A power stages.

Although gaming is not the primary focus of the Threadripper platform, this motherboard is part of the ROG (Republic of Gamers) lineup. If you enjoy light shows, you can “RGB up” the system to your heart’s content using this board’s headers.

Pros:

• Five M.2 slots
• Aquantia ACQ-107 10G Ethernet port
• Five M.2 slots
• Wi-Fi 6/ax and Bluetooth 5

Cons:

Best ASRock: TRX40 Taichi

As per customary, ASRock offers a flagship Taichi board for the Threadripper 3000 platform. The design is similar to the X570 Taichi and features a black and silver theme. The motherboard has plenty of heatsinks that match its overall design.

In terms of power delivery, it has a 16-phase power design with black capacitors that match the aesthetic of the motherboard.

The chipset has dual cooling fans to keep the thermals in check. These should be great for cooling but they are nevertheless additional moving parts that make some noise and may fail eventually. On the other hand, this appears to be very common with PCIe 4.0 motherboards even in the mainstream segment.

Additionally, the board features Wi-Fi 6 for fast wireless speeds. It also supports the Hyper Quad M.2 add-in card, which provides four additional M.2 slots if you need lots of ultra-fast storage space. All these features make this TRX40 motherboard great for 3rd-generation Threadripper CPUs. It also comes with a BIOS flashback button in case anything goes wrong.

Best Value TRX40 Motherboards

None of the boards that support this high-end platform are inexpensive. But by scaling back on some of the less important features, most builders can save quite a lot and still get a very powerful board with everything they will ever use. These are our top picks that compromise the least in the critical areas.

Asus ROG STRIX TRX40-E Gaming

This high-end alternative from Asus might not be the most sophisticated model, but it looks impressive overall. As it’s an Asus product, you get the usual ROG Strix looks with some RGB added. The motherboard has 16 power stages and dual 8-pin power connectors for the CPU.

Moreover, it features a large heatsink and a fan for cooling the VRM. The board’s 8 RAM slots support 4400+ MHz OC speeds. It has three M.2 slots, two of which are hidden beneath the massive heatsink and get cooled from the fan. You also get plenty of connectors for storage.

The Strix comes with Wi-Fi 6 and also has an onboard OLED that can be customized, as well as a premounted I/O shield for easy installation. This is DIY-friendly and ideal for people who want to build their own PCs.

Pros:

• 16 power stages
• Wi-Fi 6
• A bit cheaper than the premium options

Cons:

• A “gaming” design might not appeal to all

The Asus ROG STRIX TRX40-E is a bit more affordable than the other models that we have looked at on this list but it still offers a very nice feature set and lots of I/O.

Manufacturer’s product page

Gigabyte TRX40 Aorus Master

A slight step down in the TRX40 range from Gigabyte, we find the TRX40 Aorus Master. The design and color scheme of the board is similar to other Gigabyte motherboards that we’ve seen. It features the customary eight RAM slots and supports 4400+ MHz memory in quad-channel mode. Its 16+3 phase VRM should be more than capable of handling all Threadripper 3000-series CPUs.

For blazing-fast Internet speeds, you get AQUANTIA 5 GbE LAN and Intel GbE with cFosSpeed, but it also includes Wi-Fi 6. The motherboard features 4 M.2 slots and each of them comes with a heatsink. Additionally, it comes with the USB TurboCharger feature for fast charging of mobile devices.

As with all high-end Gigabyte motherboards, you get RGB FUSION 2.0 in different zones of the motherboard as well as RGB headers for syncing the lighting effects with other supported parts and peripherals. The Q-Flash Plus feature allows the user to update the BIOS without installing a CPU, GPU, or RAM, which can come in handy in many situations.

Pros:

• 5 GbE LAN + Intel GbE LAN with cFosSpeed
• 4 M.2 Slots
• Wi-Fi 6
• Q-Flash Plus feature

Cons:

• Design is very similar to older models

The TRX40 Aorus Master comes with most of the bells and whistles that you can ask for in a high-end motherboard. It should be ideal for content creators who need the extra I/O along with the extra cores and threads.

Manufacturer’s product page

Asus Prime TRX40-Pro

The Asus Prime TRX40 Pro is a somewhat more wallet-friendly option with a relatively clean look as compared to other motherboards on this list. What makes the board stand out is mainly that it comes in white.

It has an integrated I/O shield for easy installation and like all the other motherboards on this list, this one comes with 8 RAM slots that support 4400+ MHz RAM. The VRM components are cooled properly with heatsinks and there is an active cooling fan on the chipset as well.

Other highlights of this motherboard include 16 power stages, RGB lighting headers, and three M.2 slots for fast PCIe 4.0 storage. To keep costs down, you will have to do without Wi-Fi or high-speed LAN, but you get plenty of the usual connectivity including USB Type-C.

Pros:

• Integrated I/O shield
• 16 power stages
• Three M.2 Slots

Cons:

• No Wi-Fi or ultra-fast LAN

Although no Threadripper system can be called affordable, the Asus Prime TRX40 Pro is comparatively cheap compared to the other motherboards on offer for this platform. While it doesn’t have onboard Wi-Fi or ultra-fast wired LAN, far from everyone will be able to utilize (or want to pay extra for) 10 GbE or onboard OLED panels.
