I found the perfect power supplyhttp://www.newegg.com/Product/Product.aspx?Item=N82E16817256086
SILVERSTONE ST65F-G 650W ATX 12V v2.3 / EPS 12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply
Compact 140mm Depth Design for Easy Integration
2x 6 pin and 2x 2+6 pin pci-e
It may be 140 dollars but if you want a fully modular 140mm depth power supply that's at least 600 watts there is really no other option even. I can't find a single other 600+ watt fully modular 140mm depth psu with proper pci-e connectors.
