5 Excellent PSUtheonetruewill | 22/01/2008 | See all theonetruewill's reviews (4)Corsair Power supplies are manufactured by Seasonic- one of the best companies that currently make PSU's. These Corsair 450W variants are based off Seasonic's fantastically stable 430W, but are a newer revision as it were. The design uses only a single 12v rail at 33A peak power. However unlike other manufactures this is actually pretty damn correct, not merely a hopeful piece of fiction. For most mid-range dual-core PC's this will be more than sufficient and will probably allow you an 8800GT if you're not too taxing with any processor overclocks.
