I have Asus Sabertooth fx 990 R2.0 gen2. I updated new bios (2901) which offers NVMe support.
Can I use the Samsung 950 Pro 512GB as a system disk (via adapter m2-PCIe)?
Welcome at Win-RAID Forum!
If your current mainboard BIOS offers NVMe support, you should be able to use the Samsung 950 Pro as bootable system drive (pre-condition: You have to install Win10 in UEFI mode).
