X570 Power Delivery Specification & Comparison

One of the most talked about aspects of any high-end motherboard lately is the quality of its power delivery system. At a high level, all X570 motherboards have to adhere to a couple of factors, the most important of which is support for the upcoming Ryzen 3950X 16c/32t processor. This means manufacturers needed to work even harder in creating suitable and efficient power delivery systems to ensure full compatibility with the Ryzen 3000 series.

Meanwhile, we're also keeping a look out for any cases where manufacturers may be embellishing their power delivery claims, advertising a board as being more capable than it really is. After some bad history and what has happened in the last two years there, we hope to (and expect) to see less of that with the X570 chipset.

As power delivery is usually one of the most requested items for any of our motherboard content, prior to the launch we reached out to all the motherboard vendors to find out what power delivery systems each of their new X570 boards are equipped with. Below is a table of the official information we have compiled from each of the vendors, with a question mark (?) denotes when we don't have information available.

Please note that this information is self-reported, so until we can review any given X570 board, we're operating on the honor system, trusting vendors to supply honest and upfront information. And we will be checking, and we will be keeping this page up-to-date as more information becomes available.

As we get more information from vendors or reputable sources, we will update the table. As we get more and more X570 boards in for review, we can go deeper into the analysis in each individual review over the upcoming months.

    Nope, I really do need that many USB ports! In the past I've used various add-in cards and hubs to achieve this, but my experiences with these devices, and their drivers, and compatibility has been spotty at best, and they also take up space or PCIe slots - hence why I'd much prefer if it was all just integrated on the board.

    Just to be clear, I don't need 10 USB 3 ports - 8 USB 3 and a pair of 2.0 would be perfect. Considering almost all of these boards have a pair of USB 2.0 headers for 4 ports in total, but cases today don't offer more than a single USB 2.0 front-panel connector - plus that these boards' IO panels have plenty of extra room - I don't see why manufacturers can't drop one of those headers and just give us an extra two rear 2.0 ports as standard.

    why not pick up a usb header to slot plate adapter, im sure you have unused card openings on the back of your case under the video card
  • DanNeely - Wednesday, July 10, 2019 - link

    More ports on the back mean fewer available headers for internal connections. x570 has 12 total USB 3.x ports; so most boards maxing out at 8 on the back and 2 headers (2 ports/header) internal seems about right. Going higher means adding either USB3 controller chips (eats PCIe lanes but gives independent ports for greater total system throughput) or on board USB3 hubs; both of which drive up costs. With making the boards PCIe4 capable already driving up costs a lot the board makers are looking to economize elsewhere.
  • shabby - Thursday, July 11, 2019 - link

    I noticed the cheap asrock boards have 8 usb3 ports in the back.

    THANK YOU SO MUCH for the VRM information! i don't even OC but i like to keep an eye on what VRMs boards are using... hopefully will help with longevity if i'm going to thrash either Vcore or SoC (keeping components like caps cooler)
  • thomasg - Tuesday, July 9, 2019 - link

    In my opinion, all those boards are just silly.
    All they bring over the 2 years old X370 platform is PCIe 4.0 support, a bit more USB 3 Gen2 as well as often a second m.2 slot.

    On the other hand, the southbridge fan is a ridiculous idea, especially consindering all the silly enormous heatsinks they mount to everything BUT the chipset.

    And for that, they go for a premium of about 60% over X370 when it was fresh.
    I paid 170 dollars for my PRIME X370-Pro day 1 (over 2 years ago), now the successor is 270 dollars.

    The WS is the only board looking buyable, but then again, it also is actively cooled and doesn't even bring NBase-T.
    I could forgive that, wouldn't they charge well above 300 dollars for it (while the other boards are close to MSRP in germany, the WS is already far below its MSPR).

    Nope, thanks, I'm skipping X570.

    "I paid 170 dollars for my PRIME X370-Pro day 1 (over 2 years ago), now the successor is 270 dollars."
    Take that up with ASUS. I can get the X570 Phantom 4 from AsRock with (4x2) power stages (which means easier 3950X oc vs your x370 Pro) for 170€.
    And for me, I'm starting to think that having 3 whole x4 slots (2 M.2, one x16) of 4.0 speeds is a nice addition versus the one 3.0 x4 M.2 and one 3.0 x2 or 2.0 x4 slot with another 2.0 x4 slot all the 4xx and 3xx mainboards offer. If I'm spending ~500€ anyway (32GB and 8 core), I might as well just spend another 170 on the mainboard vs 100 on a B450 (I need mATX, so only the MSI Mortar and AsRock Pro4 suite my needs).

    And if you need Thunderbolt or over GbE speeds, these boards are the only way to go, frankly, since the 2.0 chipset lanes of the older chipsets are just terrible for this.

    This doesn't satisfy your niche? Great, move along. That's the incredible thing about AMD supporting AM4 for this long. But no need to shit over a product that is pretty great overall, just because you don't need it's features.
  • thomasg - Thursday, July 11, 2019 - link

    Indeed, it doesn't satisfy my niche, I'm just complaining about the new downsides of the new X570 platform, and specifically the available implementations.

    I'm not telling anyone not to get one, anyone who wants to take advantage of the extras is of course free to adopt the new boards.

    I think I should be able to freely "shit over a product" as I wish without you having to take personal offense.
  • fearby - Tuesday, July 9, 2019 - link

    Being in a hot climate I'd love to know what one has the best chipset cooling.
  • gavbon - Wednesday, July 10, 2019 - link

    We are doing X570 chipset thermal analysis in our motherboard testing ;)
