Know before you buy

The RM750 features a Zero RPM fan mode, meaning the fan remains completely off during low to medium loads for silent operation. When the power supply is under heavier demand, the 135mm rifle bearing fan spins up quietly to maintain optimal temperatures.
Yes, the RM750 supports Modern Standby and Intel C6/C7 sleep states. This ensures your PC wakes up faster from sleep and manages power more efficiently when not in active use.
The RM750 features a compact 160mm length, making it compatible with the vast majority of standard ATX cases. However, you should always double-check your specific case's clearance specifications to ensure a comfortable fit for cable management.
