TX Series is guaranteed to deliver its full rated specifications in environments up to 50° C. High-quality Japanese capacitors provide uncompromised performance & reliability. It keeps up when you push your PC hard. High Efficiency Efficiency is important — less heat is generated, so your system stays cool & your energy bill is lower. TX Series PSUs are 80 PLUS certified to operate at a guaranteed 82% or better efficiency, even at maximum load. Cool & Quiet The 140mm double ball-bearing fan automatically adjusts its speed to deliver the proper amount of airflow, so high-performance power delivery isnt at the expense of noise. In fact, when youre just surfing the web, doing light office applications or otherwise keeping your TX Series PSU at less than 50% load, the fan doesnt even spin. The fan doesnt even spin at low loads, so youll enjoy virtually silent operation. & when youre pushing it hard, the double ball bearing 140mm fan adjusts its speed according to temperature, so it only works as hard as it needs to. 80 PLUS Bronze certified efficiency TX (TXM) Series delivers up to 85% efficiency under real-world load conditions. Dedicated single +12V rail A single high-amp +12V rail offers simple configuration & greater compatibility with the latest graphics cards & other high-draw components. Dependable power delivery Power ratings are for continuous delivery – not peak. Over-voltage, under-voltage, over-current & short-circuit protection provide maximum safety for your critical system components.
