With strong performance, whisper-quiet acoustics, and legendary Corsair quality, the Corsair RM Series Power Supply is the choice for your powerhouse. These PSUs are built with high-quality components, and are guaranteed to deliver clean, stable, continuous power. 80 PLUS Gold rated efficiency saves you money on your power bill, while the fully modular design with low-profile black cables allows you fast, neat builds. For optimized silence, these units are built with low-noise capacitors, and feature a Zero RPM Fan Mode which powers off the fan when load levels are light. The custom designed fan also ensures low noise operation even when it's pushed hard. Want even more? Connect it to your Corsair Link system (available separately), and you can even monitor the fan speed and +12V current directly from your desktop.
