Corsair has discovered a problem with its SF series of Platinum-certified SFX power supplies that can lead to failure when the unit is exposed to high temperatures and high humidity. Every once in a while, a bad batch will escape quality controls. Unfortunately, this time it is with the SF series. Investigation revealed that the units with a code between 194448xx to 201148xx, manufactured between October 2019 and March 2020, can potentially fail. If you own one of Corsair’s SF power supplies or just recently purchased one, you should make sure that you didn’t get one from the bad batch. Corsair has reassured its customers that the power supply might be defective, but it won’t harm your other components. According to Corsair, not every SF unit manufactured within the time frame is defective. Corsair will replace the unit free of cost and even take care of the shipping fees. We should take positive from a company like Corsair as they are open about their defect and are trying to improve it and also providing for the shipping charges to its customers.
