Detailed description：Hi! Please excuse my english.
Does this model supports PCIe Gen 3 x4 NVME SSD disks? Maybe only PCIe Gen 3 x2?
I would like to buy a WD Black SN750 NVME SSD, and its 3x4. I will not be able to return it
Thanks in advance. Best regards.

Hi!
Never mind.
Just bought and installed WD Black SN750 250GB successfully.
BIOS detected the new drive. Windows detected the new drive.
Thanks anyway.
Best regards,
Adrian
