The CX Series Modular CX850M ATX Power Supply from Corsair is an 850W power supply for basic system builds and desktop PC computer upgrades that offers reliability, low noise, and the flexibility of modular cabling. The 80 PLUS Bronze certification delivers up to 85% energy efficiency and helps to reduce fan noise during regular operation, so you'll be able to enjoy a quieter working environment. Additionally, the modular cabling system means the cables are not hard-wired to the power supply, allowing you to only use the cables you need, with the rest remaining in the box and not in your system's case where they increase clutter and interfere with the airflow. Furthermore, in terms of airflow, this PSU has a 140mm fan that is thermally controlled. This helps your system to stay quieter at idle and the larger fan diameter also helps reduce system noise even when it's processing intense workloads.

The CX Series Modular CX850M supports ATX12V 2.3/2.2/2.01 and EPS12V 2.91 standards. It is also ErP Lot 6 Compliant and features an Active Power Factor Correction (PFC) with a PF value of 0.99 that will help protect against over and under-voltage, short circuit, and over-power fluctuations. It also has an MTBF rating of 100,000 hours, a dedicated single +12V rail to help increase component compatibility, 1 x ATX connector, 1 x ETS connector, 2 x floppy connectors, 6 x 4-pin peripheral connectors, 4 x PCI-E connectors, and 8 x SATA connectors. The CX Series Modular CX850M operates on 100-240VAC at 47-63 Hz and includes a modular cable pack.
