Cables and Connectors
Fixed/Modular Main 24-pin 60 cm
ATX12V/EPS12V 4+4-pin 65 cm
PCIe 6x 6/8-pin 50 cm (+2x2 6/8-pin 15cm)
Peripheral 3x PATA 40-70 cm / 3x PATA 40-70 cm + Floppy 15cm
2x SATA 50-60 cm / 3x SATA 50-80 cm / 4x SATA 50-80 cm

Similar to the smaller models the fixed connectors (Main, ATX12V 4+4-pin) are sleeved rather cheaply. Apart from that there isn’t much reason for criticism. The flat connectors are supposed to add value to the PSU, even though they don't really improve the airflow in the case. Cooler Master disassociates the PCIe connectors (grey and wide) nicely from the peripheral connectors (black and narrow). On the homepage you can see the connector panel before buying the product. Even beginners should be able to connect the cables easily.

Six 6/8 pin- PCIe connectors can be expected on a 1KW unit, but because of the two Y-adapters eight connections can be used this way. If that’s an advantage you’ll have to judge from configuration to configuration. But it has to be put into consideration, that in case of using a Y-adapter two connectors are sharing a single cable cross-section. All other features are rather conventional. A floppy connector comes via an adapter. Nine SATA-connectors should be sufficient for most systems, but also the number of PATA connectors is acceptable.

    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.

    What a piece of S...

    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.
