CORSAIR RMe Series RM850e - 850W - ATX 3.1 - PCIe 5.1 - CP-9020296-UK

Fully modular means all cables detach from the power supply. This allows you to connect only the cables your system needs, which helps reduce clutter, improve airflow inside your PC case, and simplifies installation and cable management.

Yes, it is fully compliant with PCIe 5.1 and includes a dedicated 12V-2x6 GPU power cable, ensuring compatibility and stable power delivery for the newest high-performance graphics cards like the NVIDIA RTX 40 series.

The RM850e features a low-noise design with Zero RPM fan mode. This means the fan only spins up when the power supply is under significant load, resulting in near-silent operation during light to moderate tasks, such as web browsing or productivity.

The CORSAIR RMe Series RM850e has a Cybenetics Gold efficiency rating. This signifies that it operates at a very high efficiency (typically 87-90% or more under various loads), reducing energy waste, heat generation, and your electricity consumption.

ATX 3.1 is the latest power supply standard designed to handle the transient power spikes of modern, high-performance components, especially GPUs. Compliance ensures robust and stable power delivery, preventing system instability or shutdowns under heavy loads.

The CORSAIR RMe Series RM850e is backed by a generous seven-year manufacturer's warranty, providing long-term reliability and peace of mind regarding your investment.

No, it is crucial to *only* use the modular cables provided with your CORSAIR RM850e power supply. Cables from other PSUs, even from the same brand or series, may have different pinouts and could cause severe damage to your components if used.

Verify that the 24-pin ATX and 8-pin EPS12V CPU power cables are securely connected to both the motherboard and the power supply. Ensure the power cable is firmly plugged into the PSU and the wall outlet, and that the power switch on the back of the PSU is in the 'ON' position.

Check all modular power connections, especially to your CPU and GPU, ensuring they are seated correctly at both ends. Confirm that your system's total power draw does not exceed the PSU's 850W capacity, particularly with overclocked components. In rare cases, a faulty component could also cause instability.

The RM850e features Zero RPM mode for silent operation under low loads. If the fan runs constantly, it might be under significant load or operating in a hot environment. Clean any dust from the fan grille and ensure adequate case ventilation. If the noise is grinding or clicking, contact support as it may indicate a fan issue.

Ensure the dedicated 12V-2x6 GPU power cable or PCIe 6+2 pin cables are fully inserted into both the graphics card and the power supply. Some graphics cards require two or three separate power cables; confirm all necessary connectors are used.
