The manufacturer informed that the P750GM power supplies with a range of serial numbers from SN20243G001301 to SN20453G025430 and P850GM power supplies with a range of serial numbers from SN20343G031011 to SN20513G022635 are subject to a free replacement program at Gigabyte and its official distributors and resellers. The remaining units, the manufacturer claims, are already properly configured.
