B550m aorus pro explained

[Hydoxuos]

Okay so I was wondering how the PCIe thingies work, like how much GPUs and stuff like sound cards can it support, can someone explain it to me in beginner language? 

 

Thank you!

Well the cpu has 24 lanes, on zen 2, 16 is for the GPU and 4 is for an m.2 slot. 

As for the pcie lanes that are wired to the chipset, they're all gen 3, and you can look at the pcie layout on the manual for the board. 

Usually if you place an m.2 in a slot that is wired to the chipset some SATA ports do get blocked.  

As for the second pcie slot, other than it being at 3.0, while it is a x16 slot it isnt electrically, meaning it doesn't have the full 168 pins that a x16 slot has.

top PCIe slot connects to the CPU directly (PCIe 4.0 x16) and is the preferred slot for the graphics card. The only other PCIe slot only has PCIe 3.0 x4 at best and connects to the chipset, which is good for stuff like capture card, sound card and so on.

 

Problem with this board will be weak power delivery, just a Ryzen 7 can already make it sweat a bit

Thank you for answering, but can you explain the weak power part a bit more, the website of the board says it will lower the temperatures or something due to the "ultimate power design" Do you have any idea what this means?

Branding, the board isn't the best but can handle a 3900x or even a 3950x (though at stock i would say) just fine. 

though that is branding and is meaningless, if you're looking to buy this board, i would consider other things assuming you're not limited to it.

Do you suggest any other board for around 100-150 euros, I live in the Netherlands...

100-150 euros,

the b550m tuf plus or the mortar or the a pro are better and are pretty good.

Marketing BS, there's nothing worth praising for its power delivery (which is significantly worse than the ATX variant). Inefficient mosfets and worse heatsinks than its competitors like the Asus B550M TUF and MSI B550M Mortar.
