The modular HIPER that I have, is the Type R, which isn't carried by newegg anymore, but I did found it over at NCIXUS.com:
NCIXUS.com - Buy Hiper Type R 580W ATX12V V2 24/20 Pin Black Power Supply 120MM Blue LED PCI-E W/ Detachable Cable - HPU-4K580.
To answer taintedplay's PM, yes it can power the quad, 8800GT, 5 hard drives, and such easily....because my HIPER powered a system just like that a few months ago, without a hitch. And it was overclocked too. And Apokalipse, who has the same exact one, powers an overclocked X2 6000+, 2x HD3870s in CF, 6 hard drives, plus watercooling, and 8 x fans.
