The Ultra Products X4 1200W PSU is a beast in a small package.  This PSU comes equipped with one massive 85A +12v rail and supports 6 PCIe devices - 3x 6-pin and 3x 8-pin.  It is completely modular and features a nice large fan that provides very good cooling to this unit under normal circumstances.  When pulling 1000W through this unit some components hit 70°C as measured with an IR Thermal probe, but we experienced no stability issues. . .
