PSU clicks during specific AI workloads, not synthetic tests

By PulseAugur Editorial · [1 sources] ·

A user is experiencing a clicking and crackling noise from their power supply unit (PSU) specifically when running the default Moss Image workflow in ComfyUI with an RTX 5090 GPU. This noise does not occur with other AI workflows like Krea 2 or Qwen Image, nor does it happen during synthetic GPU load tests like FurMark. The issue appears to be related to rapid transient voltage spikes from the GPU, as lowering the power limit or flattening the voltage/frequency curve in MSI Afterburner resolves the noise. AI

IMPACT Specific AI workloads can cause hardware stress, potentially requiring power supply adjustments or undervolting.
