I built a brand new PC about a week ago. Today I powered it on and the PSU (Seasonic GX650) was emitting a weird smell. It wasn't really a burning odor but more of an ozone smell but still strong enough to cause concern. Everything was still running fine but I immediately turned everything off and tracked the smell to the PSU. The only thing different is I switched the PSU fan from Hybrid to Always On last night. Is it normal for a power supply to smell like that? I noticed it just sitting in my chair beside the PC.
