Seasonic. Corshair. Or NZXT I believe it's called? All 3 are the best. Look at the Build a Pc for $700/$1000/$1300 videos. You'll get a good idea of what is a quality PSU and what isn't.
You're most likley going to be happy with whichever you choose. The only thing speaking for the Corsair is the fact that it has a single 12V rail meaning it's easier to determine exact load limits.
Overall I think people are too narrow-minded about powersupplies. While it is good to stick with products that are known for being good, it's on the same time kinda hilarious to first ignore one product and then suggest another one, when both are made by the same company.
This EVGA powersupply is made by FSP. FSP also makes powerupplies for NZXT, Thermaltake, Be Quiet! and Antec to name a few. There are a lot more good powersupplies to choose from than it sounds from some of the comments.
Just another example, Cooler Master isn't really mentioned much when talking powersupplies. Yet their Silent Pro X series is made by CWT, the same company that makes about half of Corsairs powersupplies.
In fact the only two companies I can think of now that really make their own powersupplies are Seasonic and Enermax.
