NVM Express (NVMe) or Non-Volatile Memory Host Controller Interface Specification (NVMHCI) is a logical device interface specification for accessing non-volatile storage media attached via PCI Express (PCIe) bus.
The Asus rog g750jm motherboard does not support NVMe storage protocol.
I couldn't find any info that this laptop has an m.2 port. So, no, the 950 pro is not compatible. However, this laptop has 2 hard drives. I would suggest replacing one of the hard drives with an SSD, such as a Samsung 850 Pro.
