ASUS Prime TRX40-Pro

The last of the three TRX40 models from ASUS is the ASUS Prime TRX40-Pro. Part of its Prime series, it blends its usual white and silver aesthetic, with a more professional styling and straight-edge looks. The ATX sized PCB has plenty of features including three full-length PCIe 4.0 x16 slots, three PCIe 4.0 x4 M.2 slots, and eight SATA ports. The Prime TRX40-Pro sits towards the bottom of its TRX40 product stack offering users the basics while remaining competitive with other TRX40 models.

Focusing on the design of the ASUS Prime TRX40-Pro, its main design consists of a silver and white color scheme, with a rear panel cover doubling up as a power delivery heatsink, and a M.2 heatsink which amalgamates into the design of the chipset heatsink. The board has three PCIe 4.0 x4 M.2 slots with two of these sitting underneath a large silver aluminium heatsink, with the other M.2 slot installed vertically; an adapter comes in the accessories bundle. This also includes eight SATA ports with support for RAID 0, 1 and 10 arrays. On the PCIe front, there are three full-length PCIe 4.0 x16 slots, with a smaller PCIe 4.0 x4 slot located at the bottom. Directly below the PCIe 4.0 x4 slot is a power button, and a two-digit LED debugger. Next to this is a 

As with the vast majority of TRX40 boards at launch, the ASUS Prime TRX40-Pro has support for DDR4-4666 and 256 GB of system memory across eight slots. The CPU power delivery looks impressive for a non-enthusiast model with a 16-phase design which is controlled by an undesignated controller. We know that ASUS using teamed power stages as they did with its X570 product stack. Delivering power to the CPU is a pair of 8-pin 12 V ATX CPU power connectors, with one located at either side at the top of the board. For cooling, the ASUS Prime TRX40-Pro has seven 4-pin headers which include two for CPU fans, three for chassis fans, one for an AIO pump, and another for a water pump.

The rear panel includes three USB 3.1 G2 Type-A, one USB 3.1 G2 Type-C, and six USB 3.1 G1 Type-A ports. A handily located BIOS Flashback button sits towards the left-hand side, while on the right-hand side are five color-coded 3.5 mm audio jacks and S/PDIF optical output controlled by a Realtek ALC S1220 HD audio codec. The single networking port is controlled by an Intel I211-AT Gigabit Ethernet controller.

Although the ASUS Prime TRX40-Pro omits things like Wi-Fi 6 and uprated 2.5/5/10 GbE ethernet, it still comes with an MSRP of $450. While it may seem a little off the mark in terms of pricing, the Prime TRX40-Pro has a very subtle and professional design, with a competitive feature set, and plenty of storage support for users building a workstation using the AMD Threadripper 3000 series processors.

    Still just a bit bummed .... that 1st/2nd Gen TRs have been left hangin'

    As we roll into 2020, we gotta love where AMD is going BUT, here's hoping that Dr Su does not make the same mistakes on HEDTs that Chipzillah has been notorious in making in the past. With DDR5 on the horiZen, could sTRX4 be yet another *2 and Done* in the next 18 months?

    I'm all for $800 mobos -- just as long as they don't become $50 moo-boards in January, 2021.

    Based on prior experience of AMD processors, it seems more likely that they'd have to offer new boards for DDR5 support but allow the new processors to run in older boards with DDR4. Reply

    Chances are that the TRX* series of boards will end in 2021 (or 2022 at the latest), when DDR5 is expected to roll out along with possibly Zen 5 (if 2022). That being said, I have an X399 board and a 1950X. I don't see a need to upgrade yet. I may eventually pick up a 2950X next year, but I'm hanging onto this platform. It games pretty much all current games at 4k, with the majority at maximum or high details (even on a 1080ti), and it's excellent for the development and content creation workloads that i do. Don't let the listed benchmarks fool you, the 1950X is capable of much more. Running Linux brings a rather large performance increase due to better thread scheduling among other things. I have no problems running GTA V or any other games that I play, at full 4k and maximum details. Reply

    question,
    is the amount of phases important when it comes to performance or having more devices on the motherboard ? if so how many is overkill for these motherboards ?

    Those power delivery components are only for the CPU package, and take all their power input from the auxiliary CPU power connectors (usually 8-pin, 8+4 or 8+8-pin these days).

    The rest of the motherboard get their power thru the 24-pin.

    More phases typically means better performance (thermals, quality of power, power limits) from the CPU, unless the vendor cheaps out on VRMs. I'd stay away from any board offering only a single 8-pin, as that can be a sign they are using lower quality VRMs, fewer phases, etc. Contrary to popular belief, phase doublers don't really hurt anything. A few in the youtube community have tested this, both with a CPU and also with a CPU 'emulator' that plugs into the socket and measures power output. Reply

    The question was about "devices on the motherboard", which I assume means things other than the CPU. That's why I pointed out that the phases are irrelevant to the question. Reply

    just to say such
    just "cause" the box label as 280w TDP, this does not automatically mean it USES 280w (I am sure Intel or NVDA likely many many others) will lambast the crud out of AMD for this, without giving the "full story"

    eg. Intel will say "our product X only is TDP of Y vs this massive 280w number, choose us, save the world" then when the user actually uses said "product X" they find out either A is much much slower than all review sites list it is and/or B, it shoots ACTUAL power use through the roof therefore not matching the "claims" of said product X TDP being "better" than TR gen 3 280w "listed" TDP

    Intel, NVDA have far more proven themselves on "fibbing" their numbers to make the sales than AMD has "overall" over the many years I have been involved with (consumer or otherwise) in computing

    ............

    Thanks for the review overall, at least it seems the various "partners" are not being overly foolish in terms of pricing and feature set, MSI IMO even "better" than some of the others (such as ASUS)

    I truly hope these turn out to be the "cat's meow" for those whom can afford and use them, it helps AMD, helps their partners, the long run, helps us all
