Corsair Power Supplies CX Series

CX Series™ power supply units provide 80 PLUS Bronze efficiency at a competitive price point featuring black cable sleeving and connectors and a thermally controlled 120mm fan. When you're not planning to put your PC under higher loads, such as a work computer with a basic (or integrated) GPU, a basic and reliable power supply will do the job. You won't be drawing much power from the wall, so efficiency doesn't really impact your PC much. While a PSU delivering only basic power to your components won't make much noise, you should keep in mind that these PSUs do not have a Zero RPM mode.

Corsair Power Supplies SF Series

Corsair SF-L Series Fully Modular SFX Power Supplies with ATX 3.0 and PCIe 5.0 compliance provide the continuous high wattages demanded by the latest PC hardware, all in a space-saving SFX-L form factor. If you're building a small form-factor PC, size isn't everything. SFF PCs face greater cooling challenges since less space restricts airflow, and you don't have the space for a dozen fans to drive it. CORSAIR SF SERIES PSUs are rated up to 80 PLUS Platinum efficiency, lowering the strain on your case temperatures even while keeping to a compact size limitation.

WHY YOUR PSU MATTERS

NOT ALL PSUs ARE CREATED EQUAL

Your power supply is the driving force of your system. It powers all your components, defines your potential upgrades, and ideally does so efficiently while keeping noise to a minimum.

When choosing your PSU, first decide what you expect of it. How much power are you going to need at peak load? How important is power efficiency to you? Always keep in mind that some portion of your power is lost as heat, and pay attention to the efficiency rating.

See below for more details on these factors, and how the CORSAIR PSU lineup measures up with your priorities.

HOW DO YOU RECOGNIZE QUALITY?

Every CORSAIR power supply meets our rigorous standards for the quality of critical components such as transistors and transformers, higher wire gauge cables with built-in capacitors, and more. We stand by that with a 7+ year warranty as your guarantee that your CORSAIR PSU will deliver dependable power long after all your other components have been upgraded.
