I was running a small AI training setup at home and noticed occasional slowdowns when all GPUs were under full load. It made me wonder if PSU stability or ripple might be affecting performance. Has anyone seen instability like this in multi-GPU systems?
I don’t run AI clusters myself, but I’ve worked around systems where multi-GPU loads are common, and PSU behavior often gets overlooked until performance starts fluctuating. Most people focus on cooling or drivers, but power delivery stability quietly affects consistency under long workloads.
