If you do not need a software interface like Corsair Link, you will get very similar technology with the RM power supplies at a lower price. The 850-watt Corsair RM850 offered here offers fully-featured cable management, a quiet 135 mm semi-passive fan and a 10-year warranty.
The features of the Corsair RM850 at a glance:
- 850 watt power supply with very strong 70.8 A single-rail
- High efficiency with 80 PLUS Gold certification
- Quiet 135mm fan with rifle bearing
- Semi-passive construction for noiseless operation under low load
- Fully modular cable management with flat cables
The features of the Corsair RM850 in detail
High-quality technology in a classy-simple look with high functionality, that is the principle regarding the outer design of the RM series. A large 135 mm fan ensures sufficient cooling of the electronics and is also controlled depending on the heat development. Its rifle bearing (Rifle Bearing) ensures a quiet, quiet operation at all speeds. The Corsair power supply has been semi-passively designed to operate absolutely noiselessly when idling. This means that the fan does not start up at low load of the power supply, because an additional cooling is not necessary. This results in an absolutely noiseless operation. The efficiency reaches on average 90 percent, so it has been awarded the 80 PLUS Gold certificate.
Despite the lower price compared to HXi and RMi Corsair does not save on the electronics in the RM series: Thanks to DC-DC voltage conversion, voltage regulation is above all doubt. The output voltages are always close to the setpoint even in demanding scenarios such as full load or asymmetric load. The components are also based on quality: Only high quality capacitors are used. These are considered to be particularly durable. A full ten-year manufacturer's warranty demonstrates confidence in the quality of components and processing in the RM series.
With a total output of 850 watts and a powerful + 12-volt single-rail, the RM850 can supply even the most demanding systems, including two high-end graphics cards, with permanent and stable power. To be able to provide this enormous power also to each device, the power supply offers sufficient connections for the most different hardware configurations. All connectors are modular and only need to be connected to the power supply when needed. This benefits both the appearance and the air flow in the housing. In addition to the 20 + 4-pin connector and two 4 + 4-pin ports for powering the motherboard and CPU are six 6 + 2-pin PCIe plugs for graphics available. With twelve SATA and four 4-pin Molex connectors, all systems in this performance class can be operated without adapter and craft solutions.
