Yes, this is an excellent power supply and an excellent replace for your current.

It is a great PSU, though you can achieve better for cheaper.

Typically, a rig built around a single GPU (in the likes of a GTX 1070/1080 or RX 580) build would only need a good quality 550W PSU (with more than enough headroom already).

The Corsair RMx series, at 10-year warranty, are also something to consider for its great-quality (similar to the EVGA SuperNova G2's).

Yes, 550w is more than enough.

Certainly. The 550W is a good PSU wattage for you (unlike the 600 or 650) that already takes into account the possibility of upgrading that 760 (a 170W GPU) to more powerful GPUs (or other components) in the future.

In fact, even a 450W-500W PSU will power your 760 rig, provided, such PSU has ample PCIe connectors for your GPU model.
