The inductors are most likely the same as on C6H, i.e microfine SMDs.
FPCAPs (10K) everywhere, VDDCR_CPU filtering is taken care by 12x 470µF FPCAP tantalum caps.

any idea why ASUS's X399 boards only have 6 SATA while others such as Asrock has full 8 SATA?

However the Zenith & Prime are coming with heatpipes and fan under the top cover to cool the VRMs. :/
But does the Zenith worth the +55% pricetag over the MSI?

Strictly from a VRM standpoint, no.

NOw if the other features on the X399 Zenith Extreme justify the price, that's a totally different ballgame. Another big question will be which of these motherboard makers has the best BIOS among the X399 board manufacturers. That is also a big unknown.

I found Gigabyte and Asrock to be the best here, but YMMV. It really depends on your system configuration too.

Nick Shih currently has no plans to design a X399 OC Formula unless AMD releases the necessary overclocking information. This is also why there is not X370 OC Formula.

It's good to see that they are adding active cooling. I fear that X399 might need it. With double the cores and less room for VRMs due to the large socket along with the 4 channel RAM, there's little choice but to add more. If only it could be combined with that MSI heatsink ...

Maybe MSI will do so with their high end X399 XPower. Hopefully they will have a second "connecting" heatsink that has a lot of surface area.

At the moment I don't know about what the ASRock VRM is capable off under real conditions but according to OC3D the Zenith VRM is able to output 550W continuously (?) without 'getting really hot at all'.

Excellent. IN that case, we may not need to worry about VRM blocks.

ASUS Zenith


GIgabyte X399 Aorus Gaming 7

I am wondering how much surface area the MSI one has for the VRM heatsink.



It actually looks like a serious heatsink as opposed to a solid block of aluminum.

I'm surprised they didn't use 12K caps which they use on their WS series of boards. Not a big deal though.

As expected though, it is 8x IR3555M. Thanks for confirming. They have used this on the X99 Rampage Extreme, the X299 Rampage Extreme I think, and now the X399 Zenith Extreme.

Upsetting to see Asus only released eATX boards. Finally MSI has relaxed with their obnoxious dragons. I don't like how visible the m.2 slots are. I don't like the Aorus logo just like I didn't like the MSI's dragons. I did like the Designare boards.

The Zenith board is the most appealing to me followed by the MSI Carbon. Hopefully they make an ATX Strix board.

What about the capacitors for VDDCR_CPU and VDDCR_SOC?
You aren't allowed to leak any VRM info for the Designare, aren't you? biggrin.gif IIRC Designare boards weren't focused on a good VRM in the past.
