Well, it's a beefy PSU in general, highly rated for power users and overclockers, so I figure that's going to handle this card OK. If it doesn't, then something is very wrong.
I also picked up the Antec Nine Hundred case, which is loaded to the brim with fans and exhaust vents. Again, rated highly for gamers and such.
The parts all arrive this afternoon. I'll probably be doing a set of articles with pics going through the unboxing, building and testing process on the system.
