Product Description

Coolermaster 900W UCP (Ultimate Circuit Protection) PSU - 80% Silver Certified Efficiency

The new Coolermaster 900W UCP PSU - Certified with 80% Silver Efficiency Rating

CoolerMaster UCP (Ultimate Circuit Protection) re-defines the standard for efficient and durable computer power supplies. The UCP 900W takes center-stage as the world's 1st 80 Plus Silver certified high wattage power supply; powering systems with enough juice at 88% efficiency.

Innovative circuitry layout has resulted in industry-leading efficiency levels, thanks to the high performance active clamp switch design, dual-VRM circuit boards for maximized 12V conversion to 5V and 3.3V and re-design of circuit board layout.

The UCP series is meant for powering the high-end system setups; with circuit protection in mind to prolong the life-time of the power supply. Features that enable this includes: soft-start circuitry to limit inrush currents (a Cooler Master unique feature) and the usage of quality components such as solid capacitors and intelligent fan control.

With ever increasing global demand on, it is becoming more important as a power supply provider to offer efficien energy. We are ecstatic to have accomplished this with the introduction of the UCP 900W.


   1. VRM(Voltage Regulation Module) Circuit offers high efficiency and Power density.
   2. Compliance with the newest Intel standard ATX 12V V2.3
   3. Compliance with the newest SSI standard EPS 12V V2.92
   4. Ultra-silent operation with intelligent 120mm fan speed control
   5. Eco-design for energy and money saving by Active PFC.(>0.9) / high efficiency(>88%)
   6. Power Failure Detector will light up when OVP /OCP / OPP / SCP / UVP /OTP occur
   7. Soft-start circuit A protection mechanism that limits the input inrush current by delaying the actual power-on of the PSU to prevent damage to it.
   8. Green mode PFC control circuit by intelligent PWM power conversion
   9. By using a single 12V switching circuit design you get a more efficient AC to DC conversion which leads to an overall more efficient PSU
