The matt black finish, black sleeved cables and black connectors give the CX550M a high-tech look. The clever thermally controlled fan design allows for little or no detectable fan noise during normal use, which gives an 80 PLUS BRONZE certified efficiency rating. This CX550M has been tested to strict Corsair standards for a trouble-free installation. On the CX550M PSU the peripheral power cables are not hard-wired to the power supply, you can connect only the cables you need for your exact configuration of PCI-E cards and storage devices. The rest of the cables stay in the box, and not in your PC’s case where they can add to the clutter and interfere with airflow. Power without safety is pointless, so a full suite of top tier circuit protection is built-in, keeping you running strong and your hardware safe. These include Over and Under Voltage Protection, Over Power Protection, Over Temperature Protection and Short Circuit Protection. This PSU features an 80 Plus certification, ensuring your power supply is not wasting power and turning it into excess heat. Under typical load, this power supply is 85% efficient or higher. Get reliable power and protection for years to come.
