Thermaltake Toughpower 1350W 80PLUS Silver Certified Continuous Power SLI-ready CrossFireX Certified AMD GAME Ready Modular Power Supply TP-1350M. ATI CrossFireX Certified and NVIDIA SLI-ready to support multi-graphic card configuration with up to eight PCI-E power connectors. 80PLUS Silver certified to bring you energy bill saving that you can actually see with 85%, 88%, and 85% power efficiency at 20%, 50%, and 100% loading respectively. Advanced DC to DC converters for 3.3V and 5V rails to achieve highest power efficiency. Oversized and highly effective 140mm dual ball-bearing fan ensures all critical components within the power supply are properly cooled without adding additional noise output thanks to the built-in full-range automatic temperature control system that adjusts the fan speed to adapt to different loading scenarios. Smart cable management not only enables professional-looking system build, but also accelerates airflow through the computer case for highly efficient heat dissipation. Dual +12V rail design with massive 60A on each rails (120A total), power users can now truly enjoy continuous and consistent power delivery to each and every components, even at ambient temperature of up to 50 C.
