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.

    looks like the two ASRock and at least two, if not three of the three MSI use LOTES sockets. i expect FOXCONN to be the same trash that freaked me the f out trying to screw down the CPU cover on my X399 Designare EX (see HardOCP's Kyle having the same difficulty tightening his down, but mine seemed even worse).

    Although ASRock TRX40 Creator is classified as ATX, the last PCI slot probably cannot take a double-width card (even though the manual on page 41 talks about installing 4 SLI double-width GPUs). ATX size specification says 7 PCI slots; but 4x2=8. Am I right? Reply

    Good review, thank you. Reply

    do you guys think that the MSI TRX40 Pro would be a good candidate for a 3960X with some light overclocking? i've had multiple really bad experiences with gigafail, and if you check gigbayte x399 reviews on newegg, amazon and other places, other people did too. so gigabyte is a hard pass for me.

    Prices are going up and up with AMD, much more than anything Intel had ever priced. Zenith II is $850 and TR flagship model is expected to be at least $4000. AMD "wins again" but will AMD fans win yet? Reply

    dwade123, and look what intel did to the prices before they released zen. how much were you paying for QUAD core cpus, where the performance increase over the previous gen was 10% or less. intel cant complete with amd in multi thread performance, the ONLY way intel has any performance advantage over amd, is due to clock speed, thats all..

    imagine where intel cpu's would be if there was NO Zen....

    dwade123 " Prices are going up and up with AMD, much more than anything Intel had ever priced " you sure about that ?? intels top end i9 chips were VERY expensive here, most of their i7 line was also expensive... but yet.. HOW was intel able to drop the prices like they HAD to do with the 10xxx series over the 9xxx series ??? people now complain that amd is priced to high, where were all of these people when intel was priced just as high, if not higher ??? it seems.. its ok for intel to do something.. but when amd does it.. all of a sudden its wrong and its a crime?? come on...intel cant compete with amd in almost everything now, the ONLY thing intel has left, is single thread performance, and even that, isnt by that much, and its ONLY cause of clock speed.. its about time amd was able to charge what they are for some of their chips, because the performance is there.. when intel catches up, intel will probably charge the same.. dwade123, you better be complaining about intels prices then as well....

    Why the heck would you use the same physical socket keying. Reply
  • Korguz - Monday, December 2, 2019 - link

    the socket is the same.. but the pins i think are different Reply
