Cooler Master's new Ultimate Circuit Protection 900W power supply makes a great impression when you look at it. The durable metal flake paint is very unique and built to last, it does not take fingerprints and is very hard to scratch. If you plan to use a bigger case this might be the PSU of choice since all cables are 10 cm longer than on most other power supplies. There is just one completely retarded design choice which is the non-standard power connector. It makes your and Cooler Master's life harder without having any benefit other than being "special".
During our testing the UCP 900W showed good voltage stability, especially on the 3.3V and 5V rails. It is safe to say that this unit will power every enthusiast rig you can throw at it. While our testing does not confirm the high efficiency of the UCP 900, the official testing at 80plus.org says 88.14%, which makes this the first 80plus Silver PSU on the market.
Overall the Cooler Master Ultimate Circuit Protection is a solid choice for everyone who is looking for a PSU in the 900W range and is willing to pay the price of around € 220 which definitely includes a small premium for the brand name and the exterior design.
