I'd go with the Corsair if it had to be out of the two of those. I have fairly strict brand preferences so my opinion may not be the best to take. I'm sure there are other great power supplies out there for less, but I would not "settle for less" than a Corsair. If that makes any sense.
Pertaining to my strict brand filters, I only use OCZ on Evga boards. OCZ has proven itself to work in sync well with Nvidia chipsets.
OCZ Gold PC3-12800
EDIT: oh hahaha. Gibson did this earlier. I called the X58 chipset a "Nvidia chipset". My mistake, it's an Intel chipset. I meant to say Evga, but like most, when I hear Evga, I immediately associate the name to Nvidia products as that's mostly what they make.
