Whats Difference Blue PCI-E and Black PCI-E

[kemalettinabluka]

I have Asus P8H77M-PRO. I want buy Asus GTX 1050 Ti but SATA port dimension is problem. I think if I use black PCI-E port maybe compatible with motherboard.

1 x PCIe 3.0/2.0 x16 ((Blue))
1 x PCIe 2.0 x16 (x4 mode, (Black))

The black port only runs at pci-e 2.0 4x speeds while the blue is pci-e 3.0 16x. The sata ports will not get in the way of a gpu if you are using a sata cable(s) with a straight connector as the card will sit above the ports.
