[SOLVED] Replacement for my CM650X?

[ItsKieranL]

I am currently looking for a new power supply as i'm going to be upgrading my pc in a month or so, my current pc consist of
Specs:
Case - NZXT H500
CPU / Processor - I7 6700k
GPU - GTX 1060 6GB
Power supply - cm650x
motherboard - Asrock z270 taichi
CPU cooler - Hyper 212x evo
ram - 2x4 Corsair vengeance LPX 2400 - CMK8GX4M2A2400C14
1x8 Hyper fury - HX424C15FB2/8

I am going to upgrading my GPU to a 2070 super and i also want some room to OC it, so should i upgrade to a 750W psu, and if so please recommend some. I've been looking for myself and these are the three that i've been looking at:
Corsair RM750X - https://www.amazon.co.uk/Corsair-RM...+psu&qid=1572711960&s=electronics&sr=1-4&th=1
Corsair RM750 - https://www.amazon.co.uk/Corsair-RM...+psu&qid=1572711960&s=electronics&sr=1-4&th=1
Corsair RM750I - https://www.amazon.co.uk/Corsair-RM...+psu&qid=1572711960&s=electronics&sr=1-4&th=1

I don't know the differences between these PSU's but all i want to know is which one is better out the three and which one will fit into my current case, case being the NZXT H500, whilst being compatible with all my other components.

You don't need anywhere near 750W for your proposed build.
