80 PLUS GOLD CERTIFIED
The RM550x can deliver power with over 90% efficiency to keep energy consumption, noise, temperatures, and your power bill low.

100% ALL JAPANESE 105°C CAPACITORS
By using high-end electrolytic capacitors, the RM550x delivers the unwavering power and long-term reliability you’ve come to expect from a CORSAIR power supply.

ZERO RPM FAN MODE
At low and medium loads the RM550x’s cooling fan doesn’t spin until you need it, for near-silent operation.
