A brief look at our SeaSonic M12II modular power supply, S12II power supply & Corsair TX850 power supply. Many common branded PSUs are not made by the company that sells them. Most companies that sell PSUs do not actually make them! SeaSonic manufactures their own power supplies, as well as for many other companies. Many of the Corsair models we've used are actually manufactured by SeaSonic. SeaSonic is the #1 power supply company in the world!
