i7 6700k GTX 1070 650 watt PSU Enough?

Hi i was curious if a Corsair RM650 would be able to safely support an i7 6700k and a MSI GTX 1070 GAMING X? I am not sure if i am going to be able to afford a new Power Supply and If my budget permits i was going to probably go with an EVGA SuperNOVA P2 850w. Would it be fine if powered by maybe A 750w PSU and would i be able to do a slight CPU overclock? Sorry for all the questions but I just want to make sure I get all the information i can before i make a purchase.

  1. 750W enough for that, also for OC. But choose a good PSU, you can check on PSU Tier List
  2. A good 550 watt PSU will be good enough. I run a intel i7 2700k with a GTX 1070 and a corsair RM750i. But my backup PSU a 550 watt antec was able to run it just fine as well.

    Do you think that i could do a slight overclock on my current Power Supply? It's a Corsair RM650
    EDIT: i mean If i could overclock the 6700k with the GTX 1070 on my 650 watt Power Supply.

    Well, that depends what other components are in your system... HDDs, SSDs, fans, blu-ray etc. but in general common setup of mobo+cpu+ram+gpu+ssd+hdd you have enought headroom for sensible OC, it even should still keep your power consumption below 350 or 400W (which should be around best effectivity spot for 650W PSU). Otoh if you have 8 HDDs, 2 high end PCIe SSDs, 3 blu-ray drives, water pump and 6 big fans.... well, you get my point ;-)
  5. Yes you can overclock with your power supply. Assuming I'm wrong worse case would be a failed overclock. But you don't really need as much power as you think you might.
  6. Ok i accidentally selected that as the answer but that did definitely help to clear everything up, I think that i will stay with my 650 watt PSU. I know this is off topic but does anyone know what tier my PSU is? I couldn't find the RM series in the tier list.

    If its just RM the it is tier 3. If it is RMi then it is tier 1. http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html

    I just upgrade to msi GTX 1070 gaming x and rm650i today
