No, the X470 Gaming Plus Max does not support ECC.
No, the X470 Gaming Plus Max does not support ECC.
You're building your first PC and the X470 Gaming Plus Max looks great. The main concern is whether it supports ECC SSDs. Since you're using Team Group MP33, which does, you can stick with ECC. You'd prefer to keep that setup and look for a different motherboard instead of swapping out the SSD entirely.
ECC assistance applies to RAM compatibility, not SSDs. Feel free to choose any NVMe or SATA SSD you prefer.
