Question What is the difference between these two B550M boards ?

[smalltech]

Hello,

Q1. What is the difference between A and B? It seems like they are the same. Please help me to spot the differences.

A. https://www.asus.com/sg/motherboards-components/motherboards/tuf-gaming/tuf-gaming-b550m-plus-wi-fi/
B. https://www.asus.com/motherboards-components/motherboards/tuf-gaming/tuf-gaming-b550m-plus-wifi-ii/

-----
update, one more question:

Q2. Is it worth the extra money to select A/B over this cheaper model https://www.asus.com/motherboards-components/motherboards/prime/prime-b550m-a-wifi-ii/

Thanks

Just the second revision. same specifications, maybe some changes in PCB trace or other internal components used.

8 phase VRM is not great. I would not suggest this board for 125W+ power draw usage.

What does 125W+ power draw usage mean?

Is using Corsair rm650 ok?

This board works fine for any AM4 CPU. I used one for an 8 core CPU (5800X) until I damaged it moving to another case. It's VRM ran very cool even running days at a time folding (Folding @ Home). But I had to measure VRM temp with an IR thermometer since Asus doesn't expose the VRM temp sensors for monitoring. Neither do they expose the memory voltage. Very cheap of them considering this is the top-of-line B550M motherboard from Asus. Maybe the V2 board fixes that.

While it is 8 phases they are highly efficient power stages, not discrete FET's, underneath a massive heat sink. I'd feel confident running even a 16 core (5950X) CPU on it.

I replaced it with a Gigabyte B550m Aorus Pro. It runs very well too but the VRM (10 phases, discrete FET's) does run hotter. While it's quite good enough for my 5800X I wouldn't put more than a 5900X on this board. But the B550m Aorus Pro V is another matter, very potent 10 phases of power stages and a full complement of sensors for monitoring. If you could find this one it's very much better than the Asus board.

What is the board that you use? I asked about 3 boards, not sure which one are you referring to.

LOL...oh yeah...the B550m TUF Gaming Plus. It was an early model so would be the V1 I suppose.

And also, it depends on the CPU you want to put on it but I'd definitely consider the TUF boards much better than the PRIME boards for more power hungry, high core count CPU's.

I am using AMD Ryzen 5600, would PRIME board be ok?

Is it CPU with more cores will be hotter so need better VRM?

Yes, more cores typically have higher power draw which makes the VRM run hotter. And people generally buy high core count CPU's because they have processing workloads that are very demanding (like image and video rendering for instance) and uses all those cores quite heavily.

The PRIME board would be adequate for a 5600.

DVI-D, D-Sub, HDMI and DisplayPort on the motherboard are they only usable if I am using integrated graphics (e.g. 5600G), no use for these ports if I am using dedicated graphics cards?

That is correct.
