If you own one of Corsair’s SF Series power supplies, you may want to think about getting it replaced. According to a post on the company’s official forum, PSUs belonging to lot codes 194448xx to 201148xx (and with a manufacturing date between October 2019 and March 2020) could be susceptible to failure when exposed to a combination of high temperatures and humidity.
“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,” wrote Corsair. “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.”
“While this issue does not, and will not, impact every unit manufactured within this time, out of an abundance of caution and commitment to the quality of the SF-Series, we are starting a voluntary product replacement program for owners of SF PSUs within this lot code range.”
If you’re the owner of an affected PSU and would like a new one, you can hit this link and submit a ticket to Corsair’s customer service team. “Where possible, we will endeavour to offer advance replacement of units to minimize customer downtime and disruption,” noted Corsair. “The originally purchased unit will need to be returned to CORSAIR, at our expense.”
