Bring your system to life with the Thermaltake Toughpower XT TPX-675M power supply. It complies with ATX 12V v.2.3 and EPS 12V v2.91 standards. It also works with the latest CrossFireX system, and is ready to deliver 675 watts of power where you want it – safely and reliably. Active PFC (power form correction) maximizes power efficiency saving energy – and money on the power bill. Industrial-grade protections built into the power supply include defenses against over-current, short-circuit, over-voltage and no-load operating. The +12V output circuit provides stable voltage to your system. One Main connector (20 + 4 pin), one ATX 12V, one EPS 12V, six peripherals, eight SATA, one Floppy and four PCI-E connectors will cover all your components. A large, whisper-quiet 14cm fan keeps the power supply cool and operating at peak performance.
