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.

    My case fans are Noctua NF-S12A running at max 500rpm. CPU and GPU are watercooled with an external pump and radiator sitting a few meters away with acoustic isolation. So I'm pretty sure I would hear the chipset fans.
    I was expecting to shell out ~$1000 for a completly passive Gigabyte board, or even more if it had a PEX chip to use even more PCIe cards, and am very dissapointed that that doesn't exist. Any suggestions for a DIY mod?

    You are nuts if you think a tiny little low RPM chipset fan is bad. Chipset fans are inevitable (though a die shrink may temporarily make this go away until PCIE5), and the fact is, the fan on your PSU, GPU, or case fans, even at low levels, will drown out any noise from a chipset fan. Even if the PSU fan is off and you have water cooling, the case fans, at even 400 rpm, make more noise than the chipset fan. Note that it's not currently possible to have every fan in a system shut off on high end platforms, except the chipset fan itself might shut off. Even with an AIO, there must be some airflow for the radiator. Reply

    It's really more a matter of long-term reliability based on my past experience.
    If a 120mm CPU fan starts to die, get loud, burns out due to dust, or otherwise becomes damaged, it isn't an issue to replace it even 5 years from now. With a proprietary motherboard CPU/heatsink, we are at the mercy of the vendor's long-term support.

    Any motherboard s TRX with ipmi? I mean it would be a workstation or a server, a nice ipmi remote will be nice. Reply

    "the TRX40 chipset, and offers 24 PCIe 4.0 lanes to the system. That being said, eight of those are used for the CPU-to-chipset connection, leaving 16 for ports and other devices. This is on top of the 64 PCIe 4.0 lanes for the CPU: 64 + 24 = 88 PCIe 4.0 lanes total, but the x8 link in each direction between CPU and chipset gives a usable 72 PCIe 4.0 lanes for the platform."

    WHAT???

    howsabout?:

    The chipset uses 8 of the 64 lanes to create (multiplex?) 24x lanes - 8 of which are used for chipset usb & sata ports, leaving 16 lanes for various configurations of additional IO, at the discretion of the mobo maker.

    As I know, some boards have the type-c USB Gen3.2 x2 (20Gbps aggregation). Totally ignored? Reply

    The last thing an audio creator wants is some McGyvered / red-necked USB bridge hack-job of a motherboard. In this regard, the S1220 codec models are the only ones having my attention -the ASUS TRX40-Pro in particular since any Real content creator is going to stick their nose up at Wi-Fi. Does it have a secondary codec though? Thank you very much for the timely post which will, hopefully, prompt much discussion regarding the audio peculiarities. Reply

    I suppose audio creators will want to pay close attention to which socket is better suited to their work: AM4 or TR. Reply

    Can you explain further? Why would an audio creator pay attention to the onboard audio if he will use his own audio interface? Even if it's only a cheap Focusrite Scarlett, why does the S1220 matter? Reply

    Because he's young and ignorant but highly opinionated. Reply
