Hello guys, im in search of a new PSU my corsair ax860i as failed. I'm not sure what power requirements I need.

I was looking at 750w, but I'm not sure if that overkill brands and model I was looking at

Seasonic prime 750w
Evga 750 g2 /g3.

I will be overclocking my cup to 4.5 to 4.7 and overclocking the 980ti.

Either the Seasonic Focus Plus 650w or Antec High Current Gamer 650w (both are esentially the same psu in a different case) would be my choice. Both are Gold rated, fully modular and have 10 year warranties.

My basket at Overclockers UK:

1 x Seasonic Focus Plus 650W 80 Plus Gold Modular Power Supply= £92.99
1 x Antec HCG Gold 650W 80 Plus Gold Modular Power Supply= £92.99

So reckon 650w is enough?

More than enough. The pc in my siggy along with 12x 120mm fans, 4x 200mm fans, 2x fan controllers, 2x Temp monitors and a couple of leds for the reservoir only pulls 128-275w at the wall while gaming (depending on the game) and the very max I have managed to make it pull was 367w at the wall while using OCCT's psu torture test. Idling/ internet browsing is 72w at the wall. I have live power draw displayed in one of my fan controllers which is how I know what is being drawn all of the time.

Graphics card is biggest power hog.
And that's 280W max at stock.

During gaming those parts will struggle to draw 350W.

Unless just going for max overvolting it to space heater there's plenty of room.
