Power Supply Unit Corsair RM1000e 1000 W

The Corsair RM1000e 1000 W is a fully modular power supply unit designed for desktop PCs, offering compact dimensions and high-efficiency power delivery. It includes a 24-pin ATX connector, multiple universal 8-pin connectors for motherboard and GPU power, and a PCIe 5.0 12VHPWR cable for modern graphics cards. The unit is ATX 3.0 certified and 80 PLUS Gold-rated, providing stable output and high electrical performance in a smaller-than-standard housing.

Advantages

Fully modular cabling reduces clutter by allowing connection of only the cables you need, while five universal 8-pin connectors accommodate current motherboard and GPU requirements. ATX 3.0 certification ensures compliance with the latest power-supply standards. The included PCIe 5.0 12VHPWR cable supports NVIDIA GeForce RTX 40 Series and similar cards. A short-depth design frees up space behind the PSU, and Zero RPM Fan Mode allows near-silent operation at low to moderate loads. Internal design features—resonant LLC topology, DC-DC conversion and 105° industrial-grade capacitors—deliver reliable, efficient power and support Modern Standby for fast wake-from-sleep times.

• High-performance gaming systems with modern GPUs
• Custom PC builds requiring modular cabling and compact PSU size
• Workstations needing stable 1000 W power delivery
• Systems that benefit from ATX 3.0 compliance and Modern Standby support

How to use

Install the RM1000e in your PC case following the manufacturer’s mounting instructions and connect the 24-pin ATX cable to the motherboard. Attach the required 8-pin CPU and PCIe cables from the modular ports—use only the cables needed for your configuration to minimise clutter. If your GPU requires a 12VHPWR connector, use the included PCIe 5.0 12VHPWR cable. Ensure AC input is within the 100–240 V range and switch on the PSU once all connections are secure.

Recommendations

Use certified, high-quality modular cables (preferably those supplied or approved by the manufacturer) and route cables to maintain airflow. Allow adequate ventilation around the short-depth PSU and enable Zero RPM Fan Mode where supported for quieter operation at low loads. For systems with high peak power draw, ensure your case and components meet ATX 3.0 guidelines and check GPU power requirements before connecting.
