Seasonic is one of the older companies producing consumer power supplies having been founded in 1975 and entering the PC power supply production market in 1980. During that more than 30 years as a company Seasonic has cultivated lines of power supplies that are today some of the standard bearers for efficiency and quiet computing. This focus, and its reputation for quality, has lead to an explosion in production as Seasonic can be found providing OEM services on various model lines for Antec, XFX, Corsair, PSU and Cooling, and of course under its own Seasonic brand.

Efficiency

The percentage of the power drawn from the wall that is actually transferred to the components within the PC. When the components use a total of 400 watts, a system with a power supply featuring 80% efficiency would consume 400 / 0.80 = 500 watts worth of power. If you were to equip the same PC with a power supply boasting an efficiency of 90%, it would only draw 400 / 0.90 = 444 watts from the wall. This could potentially make a difference on your energy bill, but it also has other benefits. Disregarding its fan, all power that is lost inside the power supply is converted into heat. The more efficient the power supply, the lower its temperature will be, resulting in a decreased need for cooling and an increased life expectancy.

We measure an average efficiency of 89.30%, which is slightly lower than the Corsair CS-M 450W. The peak at 300W is 89.67%.
