The design objective of the Toughpower Grand series is to create a sportive, exquisite, unique and stylish power supply for high-end gamers. Its tough matte surface and red decorative line display the distinguishing feature of sportiveness, while the large air intake area with honeycomb design is reminiscent of a high-performance sports car, thus decisively enhancing the overall design. Furthermore, the 80-PLUS-Gold-certified power supply unit provides 87 to 93 per cent high efficiency at 20 to 100 per cent loading, which minimises the cost of electricity. Moreover, with its unique circuit board design, the production of wasted heat could be reduced, thus increasing efficiency in order to address the lifestyle trend of reduced carbon emissions. The aesthetic appearance of the dual-ball-bearing, flower-shaped fan enables a longer life span and dramatically lowers overall noise output by through its size of 14 cm.
