Best of all it does this with less overall power consumption. To make use of Modern Standby a compatible motherboard and CPU are also required. 80 Plus Gold Certified The RM Series delivers power at up to 90% efficiency lowering energy consumption noise temperatures and your power bill. 105°C-Rated Capacitors Using industrial-grade electrolytic capacitors RM Series power supplies offer the unwavering power and long-term reliability you demand from a CORSAIR power supply.
