Those are pretty good pictures. I don't think not mentioning Dr MOS means anything, it's an Intel spec. Any power stage is pretty much Dr MOS. Most likely SiC631/NCP302155 or a different current spec in the same series on -F. The -E does indeed seem to have slightly larger packages, you could be right about IR3555 there. Both are probably teamed as all other Asus solutions.

msi this time follows the trick used by asus--covering up the chokes with pads.
dont know what makes msi changed, in the past they said ithey wanted customers to be able to count how many chokes there visually.
asus does push so hard on x570 and b450 using ir image to show vrm temps. cant wait to see their b550 figthing guide.


and msi claims their 4pin aio pump header could controll the speed of aio pump..
as far as i know at least in the past this kind of header with larger current capabililty still cannot control the aio pump speed like asetek aio.
lots of aio with 3/4 pin header to plug to mobo 4pin fan headers are just for pump speed reading...

hello elmor, do you know why gigabyte claims sic620a on z490 ultra and aorus pro ax to be 55a drmos on official sites instead of 60a rated in the spec sheet?
their latest vrm cheatsheet of b550 even states sic651 to be 55a rated.

My best guess would be that there has been some error in the communication from engineering to marketing. Happens very frequently at all vendors.

As an X570 Aorus Xtreme owner, I can't help but chuckle while shaking my head. That B550 Aorus Master will be a very nice board for the price.

Guess I'll have to hold on to this board until it's not worth anything anymore. Especially because now whatever kind of resale value it had is gone.

They should be around the corner soon enough for release.
