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.

      "Cooler Master states that the GX 450W is the hallmark of the GX series, and one simply cannot disagree. Priced at 49.99 USD at MSRP, the price gives more reason for those that are considering a value power supply to consider this as their next purchase."

      "The Cooler Master GX 450W is a good mainstream powersupply, with high efficiency (between 81.3% and 86.4%), very good voltage regulation, and low noise and ripple levels. At a suggested price of only $50 with stores probably offering less than that the Cooler Master GX 450W is an excellent  inexpensive yet safe power supply with high efficiency."

      "The GX450 managed its full power rating at the temperature it was supposed to be able to handle, managed decent voltage regulation in the bargain, and should come in to the market at a relatively competitive price."

      "Pricing is set for about $50 USD for the GX 450W, which is less than we expected when we caught wind of the new unit. This is a very good deal considering what you get here. This power range is loaded with garbage units by questionable companies, but the Cooler Master GX 450W rises above that, offering great value for consumers on a limited budget."

      "I'm very impressed with the GX450.  I honestly didn't think a 450w power supply would power my machine.  It had no problems with my machine, even after some intense Call of Duty: Black Ops battles."
