More about : rail rails Best solution ko888 a c 849 ) Power supply January 6, 2013 4:40:08 AM The OCZ ModXStream Pro Series 500W (OCZ500MXSP) has a maximum combined +12 Volt continuous current rating of 36 Amps and has one 6-pin and one (6+2)-pin PCI Express supplementary power connectors. The Rosewill HIVE Series 650W (HIVE-650) has a maximum combined +12 Volt continuous current rating of 46 Amps and has two (6+2)-pin PCI Express supplementary power connectors. Both models are made by Sirtec (i.e. the OEM). The Rosewill HIVE Series 650W (HIVE-650) is the only one of those two PSUs that is capable of powering a system with two reference design Radeon HD 7850 graphics cards in 2-way CrossFire mode.
