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.

The Intel Z390 Chipset, What's New? EVGA Z390 Dark

    I currently have the Supermicro C9Z390-PGW awaiting to go on the test bench next week, so from a consumers standpoint, I could potentially shed light on that board. As far as the Chinese/Supermicro/Spy scandal goes, I don't want to speculate without the finer details. Reply

    Ian & Gavin, thanks for the overview.
    @ both - Question: I've read that Intel, to deal with its bad planning/capacity problems on 14 nm, has contracted the fabbing of some of its chipsets out to TSMC, specifically in TSMC's 22 nm tech. Is that correct, and did you have a chance to confirm that the new 390s used by these boards are indeed made by Intel on their 14 nm FinFET tech, or are they made by a contractor (TSMC)?

    AFAIK the chipsets being reverted to 22nm are using Intel's 22nm process in old unupgraded fabs. Doing so would be far less work than porting to a process from a different company; the latter would require massive rework to follow a completely different set of design rules. Reply
  • eastcoast_pete - Thursday, October 11, 2018 - link

    Yes, you are correct, at least for H310c chipsets, maybe more (all?). I looked at the digitimes report on Intel outsourcing to TSMC, and that, if correct, would be about chipsets fabbed in 14nm. I wonder if Anadtech could check the 390s from the newest MoBos and sleuth out if they are also a case of "back to the future - 22 is the new 14 at Intel". Reply

    Still waiting for someone to make a mini-ITX board with 4x SODIMM slots. The X299 one is interesting combined with a 9800X but I'd rather have the newer architecture with better IPC and clocks. Reply
  • gavbon - Thursday, October 11, 2018 - link

    4 x SODIMMs has no performance benefit on Z370/Z390 other than a capacity increase because of the dual channel memory controller. The ASUS Z390 Maximus Gene and Strix Z390-I support the new 32GB double capacity SODIMMs to give more options for mini-ITX users needing more capacity.

    The X299 ASRock board put 4 x RAM slots on it so it could benefit from the quad channel memory controller

    Gavon understands it..

    On ITX its all about how you use the space.. It would be sille to have 4 slots for dual channel.

    BUT! It would interesting to use only 2x SO-DIMM..

    Some of the asrock boards have 8 SATA3, 3 Ultra M.2 but it's a bit misleading as they share lanes. so you can't use 8 sata3 drivers and 3 m2 ones at the same time Reply
  • gavbon - Thursday, October 11, 2018 - link

    Yeah, it's a bit of a pain, but one of the drawbacks of a chipset designed for the desktop. Unfortunately, in that situation, it's one or the other. If I was going to use 8 x SATA drives and 3 x M.2, I would probably be using a HEDT chipset such as X299 or TR4 anyway Reply

    Spelling and grammar corrections. I did not read this whole article. You 2 goofed this one up pretty badly.

    "In the below table a question mark (?) denotes that we currently don't currently have this information available."
    Too many currentlys.
    "In the below table a question mark (?) denotes that we don't currently have this information available."

    "My take on it is that it could be easier to mount a CPU pot for extreme overclockers for some reason, as I'm sure this board is all about the performance marbles and nothing else."
    Sound bytes as a sentence (SBAAS). I've very little idea what you were trying to say. Maybe:
    "My take on it is that it could be easier to mount a CPU pot for extreme overclockers. For some reason they insist on pots. Or maybe not, as I'm sure this board is all about the performance and nothing else."

    "The new gaming themed naming structure consists of three different ranges which make a lot of sense when they deciphered; the MEG is the enthusiast gaming, MPG is performance gaming and the MAG is the arsenal gaming."
    Missing "are".
    "The new gaming themed naming structure consists of three different ranges which make a lot of sense when they're deciphered; the MEG is the enthusiast gaming, MPG is performance gaming and the MAG is the arsenal gaming."

    "The MAG essentially renames the original arsenal range of boards with a name which seems fitting etc rifle mag, a happy coincidence perhaps."
    Stray "etc".
    "The MAG essentially renames the original arsenal range of boards with a name which seems fitting i.e. rifle mag, a happy coincidence perhaps."
