Update: Just finished inserting the VRM Phases Diagram on the Power Section of the spreadsheet. These diagrams will complement the text-based data on the quantities of MOSFETs/Power Stages, Gate Drivers, and Phase Doublers (if any) used per motherboard model, and shows how the PWM Controller's signal flows to the CPU and SoC VCC phases, respectively.

I have a small request for the sheet. Some of the motherboards don't have a VRM-temperature reader such as the ROG Strix B550-F, while the B550-E has a VRM-temperature reader. It would be very helpful if it was possible to omit the motherboards without one.

  1. uP1961S is a dual driver with doubler. Thus it has real phases that should be marked as "X+X"
  2. Phases can not be doubled "via Parallel Power Stage Layout". It doubles power stages not phases.

any particular reason the Asrock Rack boards aren't on here? not demanding anything or upset, just curious if there was a reason...

thanks for the spreadsheet, tho. freakin' loooove it!

Hello! Just regged so i could say thank you for this amazing list! And coupled with a question or so.

Earlier today i got a good deal for Asus strix b450-f gaming II. Due everything else was out of stock i initially wanted. But i liked the feature set on the board and connections.
I know the orginal F was considered bad, hence i hesitated abit.

i've now googled to try find review on this thing but there's none yet due it's only been out for 1 month or so.

But yea i ended up buying it due it was 110$ish and for what it offers it seems like it even beat the tomahawk max i initally was going to buy. (physically in the store)

Can't wait to test this out, i've been buying piece by piece items once money allows it. So for now it'll rock a 3400g so i'm not conserned about VRM for that.

However my question now lies in. Asus claims 8+4 phase vrms. On this tier list it says 4x2 / 2x2 but is this correct? wondering due it has 0 info about anything else "to be determined"
So i wonder if it's true 8+4 or if its doubled. Not that it matters to much i suppose.

I want to know what you/you guys think about this new VRM setup for this uppgraded board. Reason i wonder is eventually i'll be going with 5000 series once support comes for it. Or stick to previous gen top end with OC on it if possible.

You guys recon this can hold up new gen or atleast previous gen? Asus claims in a reddit post that it handles ryzen 9 no problems.

I've previously been watching pretty much every single review for b450/x470 boards, to determine best for me vs budget and so on and i'm just generally interested.
But this time i'm abit unsure due i gambled on this new released board. I'd love to see a review or more info about it. (Altho i've already bought it, will be assembled next month or the one after that depending...)

Thanks in advance. :)

Hi, thanks for the message. The B450-F II is a recently-released board, thus, most information I had at the time of posting (October) were to be confirmed/determined. At that time, the initial (pre-release/marketing photos/info) may have included the same phasing scheme similar to that of the older B450-E (i.e., ASP1106/Richtek RT3667BE 6-phase PWM controller, no doublers, Richtek RT9611C single-phase drivers -- but with Vishay FETs).

I have now updated the above information based on actual product reviews (see here: https://www.profesionalreview.com/2020/11/11/asus-rog-strix-b450-f-gaming-ii-review/ ), included all other specs that were previously "to be determined".

As it turns out, the B450-F II employs a phasing scheme that uses dual-drivers WITH integrated doublers (uPI uP1961) that took the place of the single-phase RT9611C in the B450-E and the original B450-F. The PWM controller is now a uPI uP9505, similar to what Asus uses in their other "II" models (instead of the Richtek/ASP), and is located at the back of the B450-F II motherboard. The FETs employed are the same as that of the older boards -- ON Semi 4C10 and 4C06 (not Vishay).

Thus, the B450-F II does have [4+4] phases for the Vcore and [2+2] phases for the SoC -- as said in the Asus official website (8+4).

I can't comment on this board's actual performance versus the older models (as I don't test boards) -- maybe others can chime in. Though, as far as the difference in VCore VRM is concerned, the following may be surmised:

B450-F = 4 phases | 1H2L FETs per phase | 1 choke per phase
B450-E = 4 phases (faux 8, "doubling") | 2H2L FETs per phase (due to "doubling") | 2 chokes per phase (due to "doubling")
B450-F II = 8 phases (4+4) | 1H1L FETs per phase (due to dual-driver/doubler) | 1 choke per phase

Note that the B450-F II also features an additional heatsink/plate located at the back of the motherboard for most of the MOSFETs (in 6 of the 8 VCore phases).

Thanks too! No particular reason though ... maybe time constraints (or unfamiliarity with the Rack line-up, probably). Will most likely include those soon as I have already the infos on hand.

Thank you for all your hard work on creating this spreadsheet and then continuing to keep it up to date. It's amazing for picking out the differences between different motherboards and picking the right one!

Hi RaisonJohn,

First of all, thank you SO MUCH for creating and maintaining this spreadsheet. It was an amazing resource for my system build this year. I only have one comment on something it's lacking: there is no column for Bluetooth support. I know at least a few of the boards listed support Bluetooth, and it would have been really nice to be able to filter on that feature. If you could add it, that would be amazing.

Thanks again!

Any news on another update?

I'm really curious about the ASUS Tuf Gaming x570-Pro, it seems like a really good deal but I'm curious/worried about how good a deal it looks like and how much better the memory OC is compared to the "Plus" model.

Here's a couple of reviews: https://www.tomshardware.com/reviews/asus-tuf-gaming-x570-pro
