CORSAIR RMe Series RM750e 750W Fully Modular Power Supply - White - CP-9020292-UK

A fully modular power supply allows you to detach all cables from the PSU unit. This means you only connect the cables your system needs, reducing clutter inside your PC case and improving airflow.

Yes, the CORSAIR RM750e is fully compatible and features a native `12V-2x6` GPU power connector, specifically designed to power NVIDIA 40 Series graphics cards without the need for adapters.

Cybenetics Gold efficiency indicates that the power supply converts at least 87% of AC power into DC power at 10% load, and up to 90% at 50% load, under 115V. This means less energy is wasted as heat, resulting in lower electricity consumption and a cooler-running system compared to less efficient PSUs.

The RM750e is designed for very quiet operation. It features a `120mm rifle bearing fan` and `Zero RPM Fan Mode`, which means the fan doesn't spin at all under low to medium loads, making your PC virtually silent. It also holds a Cybenetics "A" Noise Rating, signifying extremely low noise levels even when the fan is active.

The CORSAIR RMe Series RM750e comes with a comprehensive seven-year warranty, ensuring reliable operation and peace of mind for an extended period.

With a compact length of 140mm, the CORSAIR RM750e is designed to fit comfortably in most enthusiast PC cases that support standard ATX power supplies. It offers good compatibility for various build sizes.

ATX 3.1 and PCIe 5.1 are the latest industry standards for power supplies and PCIe devices, respectively. Compliance means the PSU is designed to meet the advanced power demands and specifications of current and future high-performance hardware, ensuring optimal compatibility and stability for modern components.

Ensure the `24-pin ATX` and `EPS/CPU 8-pin` cables are firmly connected to both the motherboard and the PSU. Verify the PSU's master power switch is in the 'On' position, and the AC power cord is fully plugged into both the PSU and a working electrical outlet. Test the outlet with another device.

The CORSAIR RM750e features `Zero RPM Fan Mode`, meaning the fan will not spin at low to medium loads to maintain silent operation. This is normal. The fan will automatically engage when the power supply reaches a certain temperature threshold under heavier loads. If the fan still doesn't spin under heavy load, ensure nothing is physically obstructing it.

This could indicate insufficient power delivery or unstable connections. Double-check all power connections, especially to your graphics card(s) and CPU. Ensure your total system power draw does not exceed the PSU's 750W capacity. Use a power calculator to estimate your system's power requirements. If issues persist, test components individually.

Check if the noise is due to coil whine, which can occur but is generally harmless. Ensure no cables are touching the fan blades. Verify the PSU is securely mounted to reduce vibration. If it's a grinding or clicking noise and the fan is spinning, contact support.

Confirm that all `PCIe` power cables (including the `12V-2x6` for compatible cards) are fully seated in both the PSU and the graphics card. Some graphics cards require multiple `PCIe` connections; ensure all are populated. Update graphics drivers and check BIOS settings.
