It's hard to say without knowing your whole spec - but if you put it together on pcpartpicker.com, it will tell you, then add an extra 100W or so for overclocking, and buy a good brand:

Good quality Semi-Modular PSU. Has enough power for your overclocked gtx 780 & 4770k.

Ok i'll tell you full specs

Processor - Intel Core i7 4770k

Motherboard - MSI A78M-E45 AMD A78 - Want to upgrade motherboard for a full size motherboard what's got 64 GB ram allowed and alot of fan ports

Graphics card - GTX 780

Ram - 8GB Crucial Ballistix Sport

Hard drive - 1TB Western Digital Black

Case - Corsair SPEC-01 - Should i upgrade to a full size case?

CPU Cooler/Fan - Corsair h100i - Would this be good for overclocking the 4770k?

Case fans - Corsair AF120 - I've added these to the h100i as they are very quiet - Should i upgrade? If i do i need quiet don't care about looks

What watt/power do you guys think i'll need and thanks for everyone's help!

650w should suffice. However the EVGA Supernova 750w g2 mentioned by chris, is a very good PSU & for $90 its a great deal.

Also, you might have a hard time fitting the H100i in your case.

Check out Corsair 500r

Ok Bartholomew will the 650w be ok for overclocking the CPU and Graphic card? and I've got the h100i in my case my case but that 500r doesn't look to bad maybe when i get some more money i'll buy one!

 

[bartholomew]

Yes. But, only go for a good quality PSU!
You don't want to put the safety of your expensive hardware on the hands of a crappy PSU.

 

[George002000]

I'm a big fan on corsair i'll probly go with a corsair 650w
