Spec me a new power supply please

[meh?]

Currently rocking an old OCZ ZS 650w power supply which came with my old prebuilt pc.

I'm in the process of building a new X99 system in a Enthoo Evolve ATX case.

The power supply has to power the following:

6850k i7
1070gtx
2 SSD's
AIO cooler
I would also like to add another GPU sometime next year.

I would also like to use some sleeved cables, I have a budget of £250 for the power supply and the sleeved cables.

As you can see I don't have a clue when it comes to power supplies, so any help would be great thanks!

Thanks for that I'm thinking the:
1 x EVGA Supernova P2 750W '80 Plus Platinum' Modular Power Supply= £132.95

Should suit my needs perfectly, now to find some sleeved cables / extensions

Thanks again for your help!

Thanks for all the help it's greatly appreciated. Because of my budget I'm going to buy the complete kit along with that power supply. Thanks once again
