The hallmark of the GX Series of power supplies is that they feature a single, highly robust 12V rail that efficiently and consistently delivers clean power to all of your critical components such as your processor, drives, RAM, motherboard, and graphics cards. An included double-layer EMI filter, intelligent 120mm controllable fan, and an active PFC/PWM combo controller all contribute to the overall efficiency of the power supply. All of the many features found within the GX Series contribute to its 80 Plus Certification. This efficiency allows the power supply to utilize most of the power it takes in with minimal waste, saving your electric bill. It makes the GX450W a perfect addition to a home theater PC or mid-range computer setup. Features: Compliance with the latest Intel standard ATX 12V V 2.31.
