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.

    Making a CPU that fits in a socket but doesn't work in it is idiotic. Especially considering the target market, did AMD really need to save a few pennies on getting Lotes to make slight modifications to their TR3 tooling? Reply

    "Especially considering their target market"

    System integrators, enthusiasts and experts?

    All of them have fans. Bleh. I remember chipset fans. No thanks. X570 is a piece of shit to me for the same reason (apart from that one gigabyte board that costs way too much). Reply

    Also one Asrock board which costs even more! Reply

    all be cause of a chipset fan ?? thats borderline crazy, have you even heard them ? chances are, the other fans in your case would drown it out and you wouldnt even hear it Reply

    They fail, they're usually a weird size or fitment, and they whine.. case fans are usually much larger and have a far different (and much more pleasant) tone Reply

    i have an Athlon 64 board, with a fan on the chipset, still works just fine, no issues.. nothing.. so those who are wining about these, are unfounded. Reply

    Yeah they do fail sometimes (or used to anyway), and it kinda silly that they they nowadays have these weird shapes because of aesthetics making them hard to replace. Not everyone use windowed cases.

    With that said it shouldn't be a big problem to strap a casefan on in case of failure.

    I have the X570 with chipset fan and do wish they would have solved it with a beefier heatsink instead. Seems like a cost issue (in fact I think there is at least one X570 board w/o chipset fan)

    It's not how 'beefy' a chipset is, but rather, the size of it. PCIE 4.0 is pushing the chipset, on the current node, to it's limits. A die shrink might fix this, or it might actually make the problem worse. Reply

    Chances are IF they fail, they are under warranty. If not, you can replace them. However, I've had (non-chipset) fans last for decades. I still have a fan from an old 386 system that works just fine and dandy. Reply
