I've been getting some errors occasionally with my GPU, and in the process of figuring it out, I've narrowed it down to the GPU itself, or the PSU. I haven't really paid much attention to power supplies over the years so I don't know if this is normal behavior or not.
During Idle the 12v averages about 11.85v, and when I put everything at full load (cpu, gpu, hdd) it decreases to 11.42v. It's not much of a drop, but I'm thinking it could be the problem. Any thoughts?
