Power delivery instability from transient load spikes
8/10 HighModern GPUs create transient power consumption spikes up to 2x nominal power lasting milliseconds, causing ordinary power supplies to enter protection shutdown. This particularly affects synchronized operations like model checkpointing across multiple GPUs, causing voltage regulator failures.

Modern GPUs create Transient Load Spikes. A card can consume 2x its nominal power for a millisecond. Ordinary power supply units go into protection mode (shutdown). Particularly concerning were failures during model checkpoint operations, where synchronized memory writes across multiple GPUs created power demand spikes that voltage regulators struggled to accommodate.
