Z390 Power Delivery Specifications & Comparison

Prior to the launch of the new Z390 chipset, we reached out to all of the motherboard vendors to ask what power deliveries each board is equipped with. The setup and capabilities of the power delivery system on a motherboard are becoming an ever popular buying requirement, and manufacturers have taken notice of this. Especially as we have reported in a couple of our reviews now, that some boards are being embellished with claims above and beyond what they can actually support.

As it's been one of the most requested aspects of our Z390 content, we compiled as much information as we currently have in hand. This is what we've been able to pull from manufacturers in terms of specification sheets (directly from source), as well as other board information. In the below table a question mark (?) denotes that we don't currently have this information available. We don't want to speculate on what might be there, but when we get more information we will keep this table updated.

As we get more information, we will update the table. We also have some motherboards in for review, so we can go into a deeper analysis on each individual article over the next few months.

    I love your table on "Power Delivery Comparison".
    But how do you tell how many phases each board has from your table?
    E.g. "GIGABYTE Z390 Gaming SLI" has 5+2 ISL69138 but then has 5 ISL6617A doublers leading me to the conclusion that it is a 25 + 2 phase design.
    Thanks!

    I've updated the table to make it more clear :) - The PPaks are dual channel MOSFETs so each of the GIGABYTE boards is running 10 phases, with 5 doublers = 2 phases per channel. This is the data we received directly from GIGABYTE. Reply

    Are they ALL made in China? What happened to the ones made in Taiwan from a few gens ago? :/ Reply
  • gavbon - Friday, October 12, 2018 - link

    Unfortunately, I cannot confirm this. The ASRock Z390 Taichi I have in my hands says 'designed in Taipei', but that's about it. Reply

    Gigabyte apparently has a factory in Taiwan. It seems all the rest moved production to China. Reply

    The MEG Z390 Godlike looked like such an interesting board until I checked the MSI Specifications page and realised it actually does not have the PLX chip as suspected. The PCI Express slots on the board are configured as 16x / 4x / 8x / 4x instead of 16x / 16x / 8x / 4x or 16x / 8x / 16x / 4x. It seems after PLX sold to whomever owns them now, that the price hike stopped their usage on consumer boards completely.

    I really really hope somebody comes out with a board that has a PLX chip on board.

    The Supermicro C9Z390-PGW has a Broadcom 8747 PLX PCIe switch :) Reply

    It would be a nice touch including in next MB review what pheriferals stop funcioning when too much PCI-E lanes are used. Some motherboards disable SATA ports when M.2 slot are used; others may require limiting bandwith to one PCI-E slot... etc. Before byuing a motherboard I would like to be warned that is not possibile to use all the features they are advertising.

    I wish we would get better thunderbolt support. Only one board has it built in? I'm thinking of a Taichi board and see a Thunberbolt AIC connector in the manual, but then I can't really find enough good quality posts of people having success putting it to use. I'd like to get a new external nvme ssd thunderbolt drive to run my vms off of so I can more easily take them on the road with me and use from my notebook. Reply
