350 bucks... I can build a whole d*mn system from it ... ... ... ... ... Any way, those "new" power supplies with 5! 12V lanes are cool but so expensive, there are pure quality though. The 1000W version is just a show-off, the 850 would do the same and more then enough for EVERY system, even for 4 4-cored CPUs, 4 cards in SLI, 5 HDDs and some DVD burners . OCing will not make the system THAT much hungry, make it an other 10% or so. If the 620Watt Enermax didn’t had bad reviews I would say go for that one, but I’m wondering why people have problems with it; Almost sure they didn’t split the lines well on the devices! Any way, it’s your choice . (Going to check what that "Fortron FSP Booster X3 300W Power Supply Booster" is, never saw it before...) EDIT: I needed 10 seconds for that to see that THAT thing doesn´t give you any performance but it will make you wallet lighter so YOU can run faster ...
