Help choosing a PSU

[l4mp]

Alright, so I'm getting another Gigabyte GTX 770 4gb Windforce for SLI and have no idea how big of a jump I need to make in terms of PSU. Would love to hear what would work. I've read multiple things from multiple people with many different setups. I'd love it if someone could quickly glance at my setup and help me decide. Thanks in advance

So here's my specs:
CPU: i5-2500k @ 4.6ghz
CPU Cooler: Hyper 212 Evo
GPU: Gigabyte GTX 770 4gb Windforce
Mobo: GA-Z68X-UD7-B3
PSU: Antec EarthWatts 650W
HDD: Seagate Barracuda 1TB
SSD: Samsung 840 Evo 250GB
RAM: 4x2 G.SKILL Ripjaws X Series SDRAM DDR3 1600
Case: NZXT S340

Edit: Doesn't have to be a specific PSU. Would like to know how many watts I need. Although specific PSU's are welcomed!

try SeaSonic 760W 80 + / XFX ProSeries 750W +
your ideal minimum watts is 700w

BTW I love that case

Awesome. Thank you so much. I love it too. It's simple, sexy, and the perfect price.
