Corsair has launched a voluntary product replacement program after it discovered a batch of its small-form-factor power supplies contain a fault that can result in them failing.
As Tom's Hardware reports, the fault was discovered in the SF series of Platinum-certified SFX power supplies. These smaller PSUs are ideal for anyone wanting to build a desktop PC using a very small case. The potential failure occurs when these PSUs are "exposed to a combination of both high temperatures, and high humidity," but luckily the problem is limited to a small batch.
If you own one of these power supplies, Corsair says the affected units have the lot codes 194448xx to 201148xx and were manufactured between Oct. 2019 and March 2020. The lot code can be found on the label attached to the PSU. It's the first part of the number below the barcode as the image above highlights. It's also important to point out that continuing to use the PSU will in no way risk damaging other components in your PC even if it does fail as the fault is isolated from the DC side of the transformer.
Corsair will send out an advance replacement so that you aren't left without a power supply. The company just asks for the original PSU to be returned at their expense afterwards. And requesting a replacement is easy, simply submit a ticket once you've identified you have a PSU with a lot code falling within the range stated above and then wait for your new PSU to arrive.
