Power Delivery Specifications & Comparison

One of the most discussed aspects on motherboards is the power delivery, with users generally favouring those with good specifications and efficient designs. The AMD X570 chipset heralded some appreciated improvements to its desktop range, but with AMD's 7 nm architecture stretching to the HEDT side of things , these improvements are expected of the higher-specification TRX40 models. The TRX40 chipset is similar in design to that of X570 with 'spare' PCIe 4.0 lanes designed to allow manufacturers to implement its own unique mixture of specifications through extra USB 3.1 G2 connectivity, and more PCIe 4.0 M.2. 

Please note that this information is self-reported, so until we can review any given TRX40 board, we're operating on the honor system, trusting vendors to supply honest and upfront information. As we review the hardware we will be checking, and we will be keeping this page up-to-date as more information becomes available.

Note: We reached out to ASUS about its PWM controller, and they stated that it doesn't have a part number and is made exclusively for them. As we find out more information on this, we will update the table below.

    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
