Can I use Corsair Type 4 PCIE cables for my PSU that uses Type 3 cables?

[kevle6]

I lost the PCIE cable for my Corsair power supply (a CS450M) and I just got a new graphics card. So my friend gave me his Type 4 PCIE cable from his power supply, a Corsair RM850i. It's the red circled end on this connector: https://i.imgur.com/87G2MHP.jpg that I would plug into this end on my PSU: https://i.imgur.com/hyKOuZ7.png 

The pinouts are slightly different with the spare 12V not utilised: https://i.imgur.com/wRw5MnV.png (Type 4 Left) 

Will the Type 4 PCIE cables I got from him work on my Type 3 power supply? 

Thank You!

Type 3 and Type 4 pci-e connectors should be the same.

Only ATX connector is different, rest is the same.

So you can use all but the ATX connector between Type 3 and Type 4 Corsair things...
