B450 motherboards support M2 slots for expansion cards.
You're looking to assemble your first PC with a Ryzen 2600 and a B450 motherboard. You have a Corsair NVMe SSD with M key interface and noticed some M.2 SSDs use M+B keys. Most motherboards support both M and M+B, so you don’t need to worry about compatibility. For a budget-friendly option under 90 EUR, the ASRock B450M Pro4 mATX is a solid choice. Since you're ordering from Amazon.de, it’s convenient and cost-effective.
Generally, most motherboards support both keys in the same slot.
It's acceptable if the SSD has additional keys while the slot lacks them, as long as the device itself doesn't have extra keys.
