Hi i'm trying to find out what watt PSU i need. I have the following

CPU: Intel Core i7 4790K

RAM: Corsair Vengance Pro 8GB 1866MHz
HDD: Seagate Barracuda 2TB
SSD: Samsung EVO 250GB
Optical Drive: Samsung DVD Writer
Cooler: Corsair H110

I was assuming somewhere around 630 - 700 W also it was 80+ Gold.

Go for the EVGA G2 750W. It's the best 750W PSU out right now and will give you plenty of headroom to OC. :)

If you look in the manual for your motherboard or the motherboard you are considering purchasing there will be a recommendation for the minimum wattage of power supply that you need. It will be a little hard to find but it's there somewhere. I know from personal experience. And remember when purchasing a power supply don't try to get the cheapest one you can find, get a higher-quality PS with proven reliability. A cheap PS can be dangerous or fail and damage other compliments in your system. There is a very informative and useful article on power supplies here on Tom hardware.

650W will done you fine but 750W would be good for future upgrades
