Overview

The performance, reliability and convenience of modular cabling


With high reliability, low noise and flexible cabling, the CX Series modular power supplies are an excellent choice for assembling basic systems and upgrading desktop PCs. The modular cabling system allows you to use only the cables you need. For a cleaner looking assembly and better airflow, save space and reduce clutter.

The semi-modular CX range is manufactured and tested to strict standards for smooth installation and operation. The intelligent fan design and 80 PLUS Bronze certified efficiency means that noise levels are virtually undetectable during normal operation. The matte black finish and black sheathed connectors and cables contribute to the clean, high-tech look of your system.

Modular power supply

Every Corsair power supply is designed by the California engineering team and assembled to exacting specifications. The Modular CX Series benefits from the careful design and testing of the renowned Enthusiast high-power power supplies. Power cables from peripheral devices are not soldered to the power supply. So you can connect only the cables you need to configure your PCI-E cards and storage devices.

Unused cables stay in the box, not in your PC case where they would add to the clutter and impede airflow. Once the power supply is installed, it should be hidden from view. The use of a thermally controlled fan makes the CX modular range quieter in standby. Its large diameter reduces noise, even when you put a lot of strain on the system.

    To be informed!

    Corsair quality.
    Never been disappointed with the brand, several power supplies mounted in different configurations.
    It is reliable and robust, for a secondary configuration R5 5500, B550 and RX6600.
    So far so good. Everything is running smoothly!

    What can I say about a power supply except that it seems to be sufficient to power a PC. Once again, thank you LDLC.

    Practical...

    Installed in a Sugo 11 case, the fact of having only the necessary cables is an undeniable advantage. Silent, and discreet when loaded, For my configuration, power largely sufficient (no big graphics card, and two HDD, + 1 dvd, and a SSD M2, and a processor ryzen 7, 2700, 2 RAM DDR4.
    Satisfied with the product

    No noise

    Despite the sleeve bearing fan, it does not make any noise, and over time when the fan starts to wear out, it will not be heard as it is at the bottom of the case, especially for those using a case with a compartment. The fan only starts at a certain wattage, which will increase the time before it starts to make noise.

    The cables are black, you have to pay a premium to have this rather than multicoloured cables, especially as it's only 450 watts, 57€ just for black cables surrounded by a mesh, but it's worth it because multicoloured cables are really despicable.

    Modular and silent

    I took this model after a change of case and ventirad and I am not disappointed at all. I'm not disappointed at all. Quiet, promising (future change of graphics card to be expected), modular which is practical. I've been using it for a while now and I'm not disappointed at all, but it's a great piece of equipment.

    Long live quality semi-modularity

    This power supply allows you to manage your cables intelligently for a space-saving configuration.
    I have no problems with noise. The cables provided were more than enough to power my motherboard, SSD and HDD.

    I also chose this brand because I'm confident of its durability (but then again, that's not something I can judge after only 2 weeks of use).

    So it's a good choice on a micro ATX configuration.

    Very noisy

    Semi-modular power supply at an affordable price. Black cables quite aesthetic.
    In short, everything of a good mid-range power supply with a good quality-price ratio except that it is much too noisy!
    It remained silent for the first 2 weeks then without warning it started to make a lot of noise after a few weeks of use, the only remedy being to switch off the PC... And then there is the coil whine which is not at all pleasant.
    I was happy with my purchase but after a few weeks I regretted it.

    Great food, but...

    Power supply bought to power a desktop configuration.
    It powers my Intel Pentium G4400 and an MSI B150 PC MATE.

    Power supply works perfectly, nothing to complain about, 80+ bronze certified, the fan is relatively quiet.
    Its semi-modularity allows a good enough cable management to be as clean as possible!

    However, it's a shame that the 4 SATA connectors are on the same cable. Impossible to connect a drive if it is far away (on Atx tower). A second SATA connector cable would be nice!

    The pluses

    -Sufficient power for a common configuration (desktop)
    -Quiet
    -Semi-modular
    -Price

    The -

    - only one SATA cable with 4 connectors and no possibility to connect the HDD and the drive at the same time!


    To solve this problem, there are two solutions:

    -Use the cable with the Molex connectors + a Molex/Sata adapter
    -Get another SATA cable from another power supply.

    4.5 for this power supply because of the only SATA connector cable supplied with it.

    Works but...

    The power supply works perfectly at this level, nothing to say, the fan is relatively quiet and there are enough different cables for a configuration with several hard drives or other.

    The power supply is very quiet and there are enough different cables for a configuration with several hard disks or other.
    (This is a very common problem at Corsair after a quick visit to their forums...)

    the pluses
    -Does the job

    the -s
    -Noise of a drill in your PC after a few hours
