Overview
- The Corsair RM850e is a fully modular 850W power supply built for modern, high-performance PC builds. With native support for next-generation GPUs via its dedicated 12V-2x6 cable, ATX 3.1 certification, and PCIe 5.1 compliance, it meets the power demands of current and upcoming graphics cards without additional adapters or compromises.
Efficiency and noise are core strengths. The Cybenetics Gold rating ensures efficient power delivery, reducing heat and electricity costs, while the A-rated noise performance and Zero RPM mode keep your system quiet under typical loads. The fully modular design eliminates unused cables, making builds cleaner and more manageable—especially important in compact or showcase cases.
With a 10-year warranty and 100,000-hour MTBF, the RM850e is engineered for long-term reliability. Its compact form factor (140×150×86mm) makes it compatible with a wider range of cases than larger alternatives, without compromising build quality or performance.

FAQs
Is the Corsair RM850e compatible with RTX 40-series and newer GPUs?
Yes. The RM850e includes a native 12V-2x6 cable rated for 600W, designed specifically for next-generation GPUs. It is ATX 3.1 certified and PCIe 5.1 compliant, so no adapters are required.
What does Cybenetics Gold efficiency mean?
Cybenetics Gold is an independent efficiency certification that indicates the power supply converts AC mains power to DC output with high efficiency (typically 88–90% across typical loads). This reduces heat, electricity costs, and environmental impact.
How does Zero RPM mode work?
Zero RPM mode keeps the fan stopped when the system is under low load or idle, reducing noise and extending fan life. The fan automatically restarts when power demand increases.
Why choose a fully modular power supply?
Fully modular designs let you connect only the cables you need, resulting in cleaner builds, better airflow, easier cable management, and a more professional appearance—especially beneficial in showcase cases.
What is the warranty coverage for the RM850e?
The Corsair RM850e includes a 10-year manufacturer warranty, reflecting Corsair's confidence in its reliability and build quality.
Will the RM850e fit in a compact case?
Yes. At 140×150×86mm, the RM850e is compact for an 850W unit and fits in many mid-tower and some smaller cases. Always verify your case specifications before purchase.
What does ATX 3.1 certification mean?
ATX 3.1 is the latest Intel power supply standard, ensuring compatibility with modern motherboards and support for next-generation power delivery features, including improved 12V rail management.
