VRM is absolutely the same on X99-A and X99-PRO, which is kinda weird since PRO does cost a lot more. Sabertooth also uses same low efficiency mosfets and VRM design as these 2.

On the other hand X99-S, X99-Deluxe and Rampage use far better quality mosfets. Even on X99-S which has identical VRM to Rampage, the VRM can go upwards of 65 degrees, that is in a cases with very good flow.

Luckily EK makes monoblocks for all Asus X99 boards, so, that can be easily remedied biggrin.gif

I figure you're referring to X99-A and X99-PRO/Sabertooth?
They have the exact same mosfets - OnSemi 4C85N, which are rather bad. Same driver - IR 3535. Same TUF chockes, 8x 560uF 10k capacitors. PWM chip is ASP 1257. It aint the same, it is bloody identical biggrin.gif


Well you should first inquire before saying something isnt true. As i've had all 3 on testbench, and 2 of them currently in our office.
But should you need pics and links as further proof, let me know smile.gif

Weird... I got the X99-S but it's a EU exclusive for some reason. I thought the X99-A was based on the same core family that the Deluxe, S, Pro follow?

It is generally, but asus has 2 vrm types that it reuses on x99 lineup. Probably due to cost saving as x99 boards dont have that big of sale volume. Everybody does it.

X99-S is THE board to buy if you're in europe. Only vrm difference is that rampage has "server grade" mosfets, which have exact same specs as ir3550 found on x99-s.

My mistake, I was not thinking of the A, actually. Apologies. The boards are by no means identical however.

The Deluxe has a different power delivery setup to the Rampage, but I'm sure you already knew that.

X99-A/PRO are mostly identical, only difference is in additional features - LAN, WIFI, etc. Saber is a bit different, but still same VRM.

How is Deluxe power delivery different to rampage? I'm not aware, aside from the mosfets with same exact specs but "server grade" on Rampage.

This is where you need a deeper understanding of the power up phases and delivery on these boards simply beyond looking at what is in front of you. Bot the X99-S and Deluxe have different power delivery methods to the R5E.

Explaining exactly how this is, I'm not afraid to admit is a little out of my depth - but if watching this space, I'm sure I can find (ask) an explanation to get your head around.
