The RM850i 850W 80 PLUS Gold Fully Modular Power Supply Unit from Corsair delivers up to 850 watts of power to your computer's components. It provides enough energy for up to ten SATA drives and six PCIe cards. Furthermore, you can use this power supply with a 4th generation Haswell Intel Core processor and a Z87 motherboard. To help ensure the delivery of power, it is built with Japanese 221°F (105°C) capacitors. The cables are fully modular, allowing for fast and neat builds as well as help maximize airflow throughout your computer's chassis. In addition, Corsair has design this power supply with an 80 PLUS Gold certification to offer you energy savings.

The RM850i supports Corsair Link Integration that lets you monitor and log fan speed, voltages, and power consumption as well as control the fan's speed and configure the +12V rail operation to single or multi. For a quieter operation, the Zero RPM Fan Mode turns off the integrated 135mm fan under light to medium loads. Additionally, the thermally controlled fan adjusts its speed as needed based upon the temperature of the power supply under heavy loads to provide optimal cooling with minimal noise.

The RM850i features Corsair Link Integration so you can monitor the performance, fan speed, and multi-rail/single rail mode.
80 PLUS Gold certified, delivering over 90% energy efficiency at real world load conditions.
The Zero RPM Fan Mode means that the fan doesn't spin until the power supply is under a heavy load. Moreover, the thermally controlled fan adjusts its speed to provide optimal cooling with minimal noise.
The integrated 135mm fan spins up as needed based upon the temperature of the power supply. In addition, the fan is built with a fluid dynamic bearing to help ensure a quiet operation.
The flat modular cable design maximizes airflow throughout your computer's chassis.
The RM850i is engineered to meet maximum power output at a server-grade 122°F (50°C) temperature rating.
You can use the fan self-test switch to see if the fan spins before installation of the power supply.
The RM850i is designed with Japanese 221°F (105°C) capacitors that deliver solid power and long-term reliability.

    RM850i 850W 80 PLUS Gold Fully Modular Power Supply Unit is rated 4.8 out of 5 by 4.
    Rated 4 out of 5 by from I love it I just finished my PC build three days ago and so far it is working great. At low loads the fan doesn't run, which keeps my rig running quite when I'm not doing anything too crazy. It looks great in my windowed case and the iLink software also works as advertised, if your curious as to how things are doing.
