To CORSAIR Customers
We have recently identified higher-than normal RMA rates among our SF family of small-form-factor PSUs. Following a thorough investigation, we have found a potential issue that can manifest when the PSU is exposed to a combination of both high temperatures, and high humidity. This regrettably can cause the PSU to fail. This issue potentially affects units in lot codes 194448xx to 201148xx, manufactured between October 2019 and March 2020
This problem can be apparent as soon as the unit is powered on for the first time, or manifest over time as the unit is exposed to a range of environmental conditions. We want to reassure customers that impacted units in no way risk damage to the components and hardware connected to your SF series PSU. This fault can occur only on the primary side of the PSU and is entirely isolated from the DC side of the PSU’s transformer that delivers power to your PC’s hardware.
