Upgrading from GeForce GTX 980 Ti (Gigabyte) to an Asus ROG-STRIX 1080ti queries.

[laevetiin]

My PC currently has a CX600 power supply, which I believe is rather old and dated considering current market psu's? Granted that's not the intended question but will help in getting specific answers. My questions in reality are do both of these cards use the same pin numbers for power supplies, will I need to upgrade my power supply to power the card, and in GPU-Z the 980ti says the Bus Interface it supports is PCI-Express 3.0 x16 but it's currently running at PCI-Express 3.0 x4. Is there really much of a difference and will that impact the 1080ti at all?
