The CS Series Modular CS850M Power Supply from Corsair is an 850W power supply for basic desktop systems where low energy use, low noise, and simple installation are essential. There is support for 4th Generation Intel Core processors (Intel Haswell and Z87 motherboards), and the 80 PLUS Gold certification delivers over 90% energy efficiency and helps to reduce operating costs and excess heat. Less heat means that the 120mm fan won't need to work as hard, so you'll be able to enjoy a quieter operating environment. Additionally, flat, sleeved, and black modular cables have well-marked connectors to help make installation straightforward. The modular cables also mean you'll only use the cables you need, and their low-profile design helps to reduce air friction and helps to maximize airflow through your computer's chassis.

The CS Series Modular CS850M meets ATX12V v2.4 and EPS 2.92 standards and it is backward compatible with ATX12V 2.2, 2.31 and ATX12V 2.01 systems. It features an Active Power Factor Correction (PFC) with a PF value of 0.99, is multi-GPU ready, will help protect against over and under-voltage, short circuit, over power, and over temperature irregularities. It also has 1 x ATX connector, 1 x ETS connector, 2 x floppy connectors, 8 x 4-pin peripheral connectors, 4 x PCI-E connectors, and 8 x SATA connectors. The CS Series Modular CS850M operates on 100-240VAC at 47-63 Hz.

Over-voltage protection, under-voltage protection, short circuit protection, over power protection, and over temperature protection help provide safety to your critical system components
