FAQs
What does 'fully modular' mean for a power supply?
A fully modular power supply allows you to detach all cables from the unit. This means you only connect the cables your PC components require, leading to a tidier build, improved airflow, and easier cable management.
Is the CORSAIR RM1000e compatible with the latest graphics cards?
Yes, it is fully compliant with PCIe 5.1 and includes a native 12V-2x6 power connector, making it directly compatible with the latest Nvidia 40 Series GPUs without needing adapters.
How quiet is this power supply?
The RM1000e features a Zero RPM Fan Mode, meaning the fan doesn't spin at low to moderate loads, providing near-silent operation. Even under higher loads, its 120mm rifle bearing fan with an optimized fan curve keeps noise levels very low, earning a Cybenetics "A" Noise Rating.
What is Cybenetics Gold efficiency?
Cybenetics Gold certification indicates that the power supply operates at a very high efficiency level, typically up to 90% at common loads. This means less energy is wasted as heat, resulting in lower electricity consumption, cooler operating temperatures, and quieter performance.
What is the warranty period for the CORSAIR RM1000e?
The CORSAIR RM1000e comes with a seven-year warranty, ensuring reliable operation and peace of mind for multiple PC builds.
Will 1000W be enough for my PC?
1000W provides substantial power, suitable for high-end gaming systems with powerful CPUs and multiple GPUs, or single top-tier GPUs like the Nvidia 40 series. For most standard gaming or office PCs, 1000W offers significant headroom. We recommend using an online PSU wattage calculator to determine your specific system's power requirements.
Troubleshooting
PC will not power on after installing the PSU.
Ensure the 24-pin motherboard power cable and the 8-pin CPU power cable are fully seated. Verify the power switch on the back of the PSU is in the 'on' position and that the mains power cable is securely plugged into both the wall outlet and the PSU. Try a different power outlet if necessary.
System experiences random crashes or instability under heavy load.
Confirm that all power connectors, especially to the GPU(s), are correctly and firmly seated. If using a high-end GPU, ensure you are using the native 12V-2x6 cable or dedicated PCIe 8-pin cables for each connector required, avoiding daisy-chaining where possible. Also, ensure your system's total power draw does not exceed the PSU's 1000W capacity.
The PSU fan is making noise at low system loads.
The RM1000e features Zero RPM Fan Mode, meaning the fan should remain off at low loads. If you hear noise, check that the fan is not obstructed by cables or dust. The fan may also spin up briefly during system startup or if the internal temperature exceeds a certain threshold, which is normal operation.

Setup, Compatibility & Care
Setup Instructions
Mounting the PSU: Secure the RM1000e into your PC case's power supply bay using the provided screws. Ensure it is oriented correctly for optimal airflow, typically with the fan facing downwards if your case has a bottom vent.
Connect Motherboard Power: Connect the 24-pin ATX cable to your motherboard's main power connector. Then, connect the 8-pin or 4+4-pin EPS/CPU power cable(s) to your motherboard.
Connect GPU Power: For the latest graphics cards, use the included native 12V-2x6 cable (PCIe 5.1) directly to your GPU. For older or multiple GPUs, use the appropriate PCIe 8-pin cables.
Connect Peripherals: Attach SATA power cables for SSDs/HDDs and Molex cables for any other peripherals as needed.
Cable Management: Utilize the fully modular design to connect only necessary cables. Route cables neatly behind the motherboard tray to improve airflow and aesthetics.
Final Checks: Before powering on, double-check all connections are seated firmly and correctly. Ensure the power switch on the back of the PSU is in the 'off' position during assembly.
Compatibility
Form Factor: Standard ATX (140mm length) fits most modern PC cases.
Standards: Compliant with Intel ATX 3.1 and PCIe 5.1, ensuring compatibility with current and future high-performance hardware.
Connectors: Includes native 12V-2x6 connector for Nvidia 40 Series GPUs, multiple PCIe 8-pin, SATA, and Molex connectors.
Care & Maintenance
Dust Cleaning: Periodically clean dust from the PSU's fan intake and exhaust vents using compressed air. Ensure the PC is powered off and unplugged before cleaning.
Airflow: Ensure your PC case has good overall airflow to prevent heat buildup around the PSU, which can impact its efficiency and lifespan.
Cable Integrity: Regularly check that all modular cables are securely connected and show no signs of wear or damage.
