The Silent Pro series is one of the best-known series power supplies from Cooler Master, previously covering range from 500 to 700 watts. The range has now extended to 1000W with two models rated at 850W and 1000W, including flat connection cables found in higher power classes. Today we are looking at the latter. The 1000W model comes with a 5-year warranty, promises a maximum efficiency of 86%, and uses a single +12V rail. Excluding the motherboard connectors all cables are fully modular. Cooler Master also makes note of the high quality of selected components. Even though the housing of the PSU seems to be very similar to the smaller Silent Pro, a different ODM is responsible for the manufacture. On the next pages we will explore the design and topology and see if Cooler Master is able to keep their promises.

    I have this PSU, it has been working ok but computer cannot go to sleep with this psu and fan is definitely audible even when no stress on hardware.

    Don't care for the flat cables at all. They are a PITA and obstruct airflow. With quiet fans available there is little need for noise these days.

    It's too bad we don't see more PSU reviews from this site more often. This is one of the few sites that properly tests PSUs.

    every review of a "cooler master" power supply that i read mentions some defect..

    having half of the air-intake blocked is stupid..

    Heatsinks have way too little surface area.

    Power Supplies this strong are made for CF and SLI gymnastics, right? So if you've got 2 or 3 high end graphic cards stacked how are you going to cool them? Passively?....I don't think so. Now, I dont know how load those coolers are going to be but one can bet they're gonna be loader than this fuss about 20dba being too load is irrelevant or should we say ridiculous...
    If you're building audio workstation...that's another story....but you're not gonna need 1000W, thats for sure...

    Who needs 1000W PS anyway.... 99,9999% of people get nothing with it but bragging rights...
    My 625W Enermax is more than I will ever need and even with that I often ask myself if I ever am gonna need that much power.... taking into consideration that my i7 920 and HD 4870 are not exactly 'power saving components'....

    Agreed. 1kW is far too much for most PCs. One of my PCs has 380W PS and the other has 330W PS. Both have a video card installed. If you have only one video card (read: 90% of PC owners), you don't need over 350W.

    for my next review I got an Antec Earth Watts Green 380W. Hope, you'll like it.
