What wattage PSU should i get for my new build?

Relevant specs are as follows:

-intel i5 2500k cpu
-evga gtx 780 gpu
-asus P8Z77-V Pro motherboard
-corsair vengeance ddr3 2x4 memory

I'm planning on overclocking like there is no tomorrow. Well i mean i havent built it yet so hopefully there is indeed a tomorrow but you get the point.

The thing is im pretty sure i could get away with a 650 ish watt PSU, but i know if i low ball it too hard i could really kill my system. On the other hand i dont want to go overboard and get a 1200w PSU because id rather spend the extra money on exotic coffee beans. So what would yall recommend for a build like mine?

  1. if you are planning for this system . so a good 700 to 750w PSU is enough for OC . . like if you have high budget so ax760 or if low so seasonic
  2. Go for Antec EarthWatts Platinum 650W 80+ Platinum Certified ATX Power Supply, as it will be good enough for your build with overclocking.
  3. You can just get a antec 900w hcg or a corsair 850 for like $10 more that will allow for future sli. both are high quality the corsair being 80+ gold... just some food for thought.
  4. If you are planning for SLI then definitely go for 850W otherwise 650w with 80+ Plat is good enough.

    With a single card setup , this is more than enough even with overclocking.
