GPU I plan on purchasing:

How many watts should I look for in a PSU to run this? Will this 620w be sufficient under a fairly heavy load? http://www.newegg.com/Product/Product.aspx?Item=N82E168...

(CM6870 motherboard, i7-3770 cpu, 16gb RAM)

The link shows an excellent 750W Seasonic. This is enough for 770 in sli. A single 770 needs at least 550W.

I would just get the 750w because it costs the same with the rebate.

(also, does this GPU I linked to have "standard" pins and whatnot to connect to my PC? I don't know a ton about hardware sooo...)

@Zaiderify:
The 620w has a -$20 promo code that expires tonight so I was hoping for a quick decision. :)

The seasonic 620 will be perfectly fine and has the necessary connections to power the GTX 770. I have the Antec HCG 620M made by seasonic.

246 Watts from the following image add that to 77 Watts max tdp of the i7-3770 that is 323 Watts or 65% of 496 (620 Watts at 80% efficiency).

It is 65% load on an extremely conservative estimate of maximum wattage compared to 80% of the power supply's rated capacity

Thank you, all! The PSU has been ordered from NewEgg. Now to decide between EVGA or ASUS for my GTX 770 OC :) 

@Goodeggray:
For some reason the link was refusing to go directly to the 620w version, it was defaulting to the 750w. Sorry
