FSP's August 2012-launched Raider series of mainstream PSUs got an efficiency upgrade to 80 Plus Silver with two new models, the 650W RA-650, and the 750W RA-750. The two feature single +12V design, handling 50A on the 650W, and 60A on the 750W models. The two are ATX v2.31 and EPS 2.92 compliant, feature most common protection features, 99% active PFC, and fixed cabling. The 650W model features two 6+2 pin PCIe connectors, while the 750W one has four. The rest of the cabling is identical: 24-pin, 4+4-pin EPS, nine SATA, three Molex, one Berg. The two are cooled by a 120 mm temperature controlled fan. Along with the Aurum 92+, the two will be available from some time in February.
