Corsair RMe Series RM850e 850W Fully Modular 80 PLUS Gold ATX Power Supply

The Corsair RMe Series RM850e is a high-efficiency, fully modular ATX power supply designed to deliver stable power for demanding desktop systems. With an 850 Watt output and 80 PLUS Gold certification, it helps reduce wasted energy while supporting cooler operation and quieter performance—an excellent choice for users building a reliable PC for gaming, content creation, or everyday productivity where system stability matters.

Fully modular design for cleaner builds

This PSU uses fully modular cabling, meaning you connect only the cables your system actually needs. That approach significantly reduces cable clutter inside the case, improving airflow and making installation easier—especially when you’re working with tight cable routing spaces. The design also supports modern motherboard and GPU power requirements through multiple universal 8-pin connectors that can be used with compatible 8-pin cables.

Low-noise cooling with Zero RPM Mode

To keep noise under control, the RM850e features a 120mm rifle-bearing fan paired with a calculated fan curve. Even under heavier loads, the fan is tuned to maintain low noise levels. At lower loads, Zero RPM Fan Mode enables near-silent operation by stopping the fan when cooling demand is minimal—ideal for quiet office setups, media consumption, and systems where you want minimal background sound during everyday tasks.

Technology built for reliability and fast wake support

Inside, the RMe Series is engineered for consistent performance using a robust resonant LLC topology with DC-DC conversion and 105°C-rated industrial-grade capacitors. This focus on component quality supports stable electrical output over time. The PSU also supports Modern Standby, helping enable extremely fast wake-from-sleep times and improved efficiency at low loads—useful for users who frequently put their PC to sleep and resume quickly.

Efficiency and power delivery you can count on

With 80 PLUS Gold certification, the RM850e is designed to deliver steady power at up to 90% efficiency. Higher efficiency typically translates into less heat generation and lower power consumption from the wall, which can be beneficial for long gaming sessions and 24/7 workloads. For buyers, this makes the RM850e a practical balance between performance and energy savings, especially when paired with power-hungry components like modern GPUs and multi-core CPUs.

Key connectivity for modern systems

The RM850e provides the essential connectors for a typical modern ATX build: one ATX (24-PIN) connector, two EPS/ATX12V (4+4-PIN) CPU connectors, three PCIe (6+2-PIN) connectors for graphics cards, seven SATA connectors for drives, and four PATA connectors for legacy devices. It also supports ATX12V Version v2.4, aligning with contemporary platform requirements.

Warranty and long-term peace of mind

Corsair backs the RM850e with a 10-year warranty, giving additional confidence for long-term ownership. With an MTBF rating of 100,000 hours, this power supply is positioned for dependable daily use—making it a strong option for users who want a quality PSU that can support upgrades and keep their system running reliably.
