Contact Silverstone, their tech support engineer said they made an engineering change to fix the OCP prematurely tripping and they will RMA your PSU.I had two SX650G power supplies which would constantly reset my computer. First one would do it usually when I tried a small overclock. The second replacement unit was even worse. I now run an EVGA 650 GM with no issues. This is with a 9900k + 2080 ti.
