No wonder, the power supply is the most overlooked component when someone is building a PC. But very few know that it is the most essential component that determines the overall performance of your PC. That’s why we have made these Corsair power supply review to help you know better.
A Power Supply Unit is the hardware of a computer that provides other computer parts with power. It converts 110-115 or 220-230 volt AC to low-voltage regulated DC power for the other computer components. Whether it is your CPU or your graphics card, all of their performance and reliability are dependent on the power supply. Without a power supply, your computer cannot even run. If a power supply goes wrong, it takes everything with it. So, choosing the power supply for your PC is the main concern here.
Corsair is one of the most reputable vendors in the field of power supply units. All their products are of good quality and more functional than any other brand in the PC world.

Zero RPM Mode- Ensures Nearly Silent Operation
Zero RPM enables quiet operation while operating under light load and moderate load. This feature makes this PSU capable of having a nearly silent operation at low and medium loads. The thermally and load-controlled fan does not spin until the PSU reaches a certain load or temperature. It started spinning above 40% load.
Fan Technology- Magnetic Levitation Bearing
This series features a magnetic levitation bearing that gives low bearing noise and the highest reliability. The magnetic levitation fan is for quiet airflow within a PSU.
