CS Series™ Modular power supplies are ideal for basic desktop systems where low energy use, low noise, and simple installation are essential.

Gold-certified efficiency and modular cabling for low energy use and easy installation

CS Series Modular power supplies are ideal for basic desktop systems where low energy use, low noise, and simple installation are essential. 80 PLUS Gold efficiency reduces operating cost and excess heat. Flat, sleeved black modular cables with clearly-marked connectors make installation fast and straightforward, with good-looking results.

80 PLUS Gold-certified efficiency

The super-efficient operation of the CS Series Modular results in lower energy use and lower operating costs. Since it generates less heat, the fan doesn’t need to work as hard, and you’ll enjoy near silent operation.

Modular cabling with clearly marked connectors

The flat, sleeved black cables are modular, so you’ll only use the cables you need and you’ll get great-looking results. The clearly-marked connectors make installation fast and straightforward.

Supports 4th Generation Intel Core processors

The low-power sleep state of the latest Intel processors can cause performance and compatibility issues with some power supplies. CS Series Modular power supplies fully support the new modes, making them an excellent choice for new PCs.

What are Corsairs replacement options?

Corsair offers the following Warranty fulfillment options:

Standard Replacement:

Through Corsairs Standard Replacement process, Corsair will issue an approved RMA number for the return and replacement of your defective product(s). Our Standard Replacement processing time from receipt of your product(s) to the replacement product(s) shipment is 1-3 business days plus transit time.

Express Replacement:

At Corsair, we understand the need to be up and running at all times! To minimize down time, we offer an Express Replacement RMA process. Through this process Corsair will ship your replacement product(s) prior to receiving your defective product(s). This process requires a valid Credit Card where a holding fee will be applied for the cost of the product until the returning product(s) are received by Corsair. To avoid being fully charged for the Express Replacement product(s), the defective product(s) must be received by Corsair within 10 business days from the date your Express Replacement order is shipped.

Accessory Product Request:

Experiencing a problem with a Corsair Component Product? Many of Corsair products have easy to install replacement accessories which will resolve the issue and prevent the need to return the entire product for replacement.

Where do I ship my items?

Corsair operates multiple RMA receiving locations worldwide. Your RMA confirmation will specify the specific return address you must use when sending your RMA package. This will be your standard return location and should not be changed without prior approval from Corsair. Any packages received at an unauthorized location may be refused and returned to the sender at the senders expense.
