Hello, my friend recently had an electrical fire while he was mining with his 2 rigs in his home. I don't how this could have possibly happened because I know he had a surge protector and aren't those things supposed to trip when there's too much voltage going through them? I believe he had 2 rigs in his room but I'm not sure if both rigs were on one wall outlet or if they had separate outlets. Also, one of the computers had a high end 7970 and I know this can generate a lot of voltage. My question is with my own mining setup am I at risk of starting an electrical fire? Right now I have one 5970 (2 gpus not crossfire) with a Corsair 750 watt PSU. I have it connected to a surge protector and it is the only plug on that surge protector. Any tips would be appreciated as I am shutting down my rig whenever I go to work just in case.
