The Toughpower PF1 series is fully modular, 80 PLUS Platinum certified and available in 650 W/750 W/850 W. In addition to the basic features listed below, the PF1 Platinum Series has two other key features - a compact size and our new board technology. With a small footprint of 140 mm (D) x 86 mm (H) x 150 mm (L), the PF1 is particularly impressive and offers plenty of space for cable management. The new board technology offers single-sided SMDs in which all IC chips are placed on one side only, so that the heat is accumulated on one side only and the entire board can be covered and cooled by the extremely quiet 120-mm fan.
