Disclaimer: Displayed parts and accessories may not be included in the actual product package.

The UCP (Ultimate Circuit Protection) series is a new generation of power supplies from Cooler Master designed with quality circuits which specialize in efficiency. With first class soft-start circuits, the lives of the primary circuit components are extended. The continuous active clamp forward switching technology and the D/D VRMs circuit design achieves over 88% efficiency which makes this of the best PSUs in the 80 Plus Silver category. The unique appearance of the UCP is made of a special coating that screams high quality and ruggedness and this is the type of things for high end PCs, especially for Quad SLI setup. Cooler Master also provides an extra-long 5-year warranty with the customer in mind!
  • VRM(Voltage Regulation Module) Circuit offers high efficiency and Power density.
  • Ultra-silent operation with intelligent 120mm fan speed control.
  • Eco-design for energy and money saving by Active PFC.(>0.9) / high efficiency(>88%).
  • Power Failure Indicator will light up if OVP /OCP / OPP / SCP / UVP /OTP occurs.
  • 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.
  • Green mode PFC control circuit by intelligent PWM power conversion.
  • 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.
  • Compliance with the newest Intel standard ATX 12V V2.3.
  • Compliance with the newest SSI standard EPS 12V V2.92.
  • Five-year warranty.

      "After removing the cover i was quite surprised to once more see how clean the entire configuration is. Cooler Master left plenty of clear space to create the best possible airflow in the device......The UCP 1100W is the flagship power supply offering from Cooler Master and one of the best power supplies on the market, of that wattage output of course. With the UCP technology Cooler Master managed to create an innovative power supply with six different circuit safety protections which are certain to protect your system by virtually any miss happenings."

      The UCP 1100W is the flagship power supply offering from Cooler Master, but don't let that fool you. It is an innovative power supply introducing several new features and combining several more all within a single power supply. It has the highest efficiency standards available in a consumer PSU, the most PCIe connectors currently available in a PSU (a total of nine), and finally six different circuit safety protections that no other power supply we have found seems to be able to offer.

      When simulating a possible real world scenario, no matter what I did, or how many applications I ran there was hardly any fluctuation when using the UCP 1100. The power provided is stable and reliable from my testing over the last couple weeks. I’ve never had a crash while running my system well overclocked with the UCP 1100 installed, even when using my overclocked Q6600. There are a few hiccups I found with this unit however. Only giving the user 5 Molex connections was a complaint I had, also the amount of wires was intimidating. It took me a bit to sort through them all to figure out what everything was.

      The PSU comes with a hefty price tag, but for this amount of wattage it is to be expected. The 5 year warrantee is very generous and isn’t something you see very much with computer components, and the reason Cooler Master are so confident and are backing it that long is because it has a rated MTBF (average time until it breaks) of over 11 years of 24/7 use, so the PSU should last for a long, long time; and in that sense could be considered a good investment. The power supply feels substantially built and it is a high (88%) efficiency unit so you are getting your moneys worth.

      With this testing method the UCP 1100 showed itself to be a very nice unit, handling the power hungry Dual Xeon Quad Core system without breaking a sweat. The only down side to the UCP 1100 was the lack of modular cabling. This may put more than a few enthusiast off, yes the UCP performs amazingly but when faced with dealing with a mass of unused cables some may skip over the UCP for less efficient and powerful models. This is a shame as the UCP 1100 is one of the best PSUs I have ever hooked up to my V8. If you are looking for something to feed the power appetite of your own voracious system the CoolerMaster UCP 1100 should be at the top of your menu.
