Zero RPM Fan Mode

At low and medium loads the cooling fan switches off entirely for near-silent operation. Once the action picks up, the fan activates, ensuring critical component temps stay in check.

For consistent, reliable power and superb electrical performance, each RM Series power supply features a robust resonant LLC topology with DC-DC conversion and 105°C rated industrial-grade capacitors. With precise timings, RMx supports Microsoft Modern Standby, ensuring extremely fast wake-from-sleep times and better low-load efficiency.
