Just got an MSI B450M PRO-VDH MAX board for a new build, and I thought I would get an NVMe drive to fit on the board and use it for my boot drive and main OS.

I have several SSDs I am hoping to use the SATA ports for, and don't really want any disabled, and I was led to believe from my reading that MVMe would leave the SATA ports all useable.

After reading up on this again a few minutes ago, it occurred to me that the board also has only one PCIe 16x slot for a graphics card that I can't afford to have disabled, and MVMe apparently can disable or share certain PCIe lanes, depending on the particular model of board.

There are two of the small PCIe 1x slots on the board as well, that I have no intention of using, and I'm wondering if MSI made it possible to disable those for the NVMe M.2 slot to be active.

I have no use for those two slots and no intention or need to use them for my machine.

Can anyone please advise as the the likelihood of the NVMe drive messing with the PCIe slots?

The box says 1x Turbo M.2 slot, supports 4 x SATA 6Gb's and 1 x PCIe 3.0 16x slot

Am I in actual fact worrying about nothing, and I can fill the board with all the components, or am I going to have to compromise and forget about the M.2 slot?

You're worrying about nothing. Throw the NVME in and call it good.

As said here just mount that SSD and don't look back. Mine is filled with what i could find, and my graphics card still has it's x16 lines available. It's only when you go to play with bifurcation settings in the bios that you can loose lanes. But you need a special riser card card for this that can hold multiple NVMe SSD. In your setup that is not the case, so just mount that SSD and enjoy your rig! And leave the settings on Auto in the bios as default.

It only matters more when you want to setup a big RAID system with multiple SSD, then you should look out that you don't take lanes away from your Graphics Card.
But for now, just use your mobo where it's made for! ;)
