Key technologies of the Corsair RM1000e computer power supply
- 80 PLUS Gold certification confirms high energy conversion efficiency
- Fully modular cabling reduces case clutter and improves airflow
- Zero RPM mode switches off the fan under low load to reduce noise
- 12V-2x6 connector directly powers modern graphics cards with high performance
- Compact depth makes installation in smaller cases easier
- Capacitors used are resistant to high operating temperatures
- ATX 3.1 standard support handles high component power spikes
Choosing a power supply
When choosing a suitable PC power supply, the key parameter besides the form factor is its power output. This indicates the maximum number of watts the power supply can continuously deliver to the computer's components. It is advisable to use a web calculator to calculate the optimal power output based on your chosen components.
ATX 3.1 and PCIe 5.1 support
This power supply meets the ATX 3.1 and PCIe 5.1 specifications. These standards define the power supply's ability to handle the high transient power spikes that modern graphics cards and processors demand during sudden load changes. This ensures full compatibility with modern-generation components and future upgrades to your build without needing to replace the power supply. It can handle even short, intense power demands.
Native 12V-2x6 cable for graphics cards
The package includes a native cable with a 12V-2x6 connector, capable of delivering up to 600W through a single wire. This solution provides direct power to high-performance graphics cards without adapters, which simplifies installation, increases the reliability of the electrical connection, and contributes to a cleaner look inside the PC case. This eliminates the need for potentially problematic adapters.
Quiet operation
Cooling is provided by a 120mm rifle bearing fan with a specially calculated fan curve to minimise operating noise. Thanks to the Zero RPM mode, the fan stops completely under low to medium loads, allowing the power supply to operate in a passive, silent mode. It only activates at higher power draws, maintaining a quiet environment during everyday work or light use.
Compact dimensions for easy installation
With a depth of just 140mm, this power supply is a compact ATX model. Its smaller dimensions make it easier to install and leave more room for cable management, even in smaller PC cases. The extra space behind the power supply simplifies cable routing and contributes to better airflow throughout the build, where every centimetre of space is valuable.
Internal components
The power supply uses a resonant LLC topology with DC-to-DC conversion for precise voltage regulation and a stable power delivery on all rails. The internal components include industrial-grade, 105°C-rated capacitors, which contribute to long-term reliability and consistent performance even under high and prolonged loads. Support for Modern Standby mode shortens the system's wake-up time from sleep.
Fully modular cabling system
The fully modular design lets you connect only the cables necessary for your particular build. This reduces the number of unused wires in the case, which improves airflow and simplifies the overall assembly. The flat design of the cables also makes them easier to organise and route behind the motherboard, making cable management neater and the final appearance of the build cleaner.
High efficiency
80 PLUS Gold and Cybenetics Gold certifications are proof of high electrical energy conversion efficiency, reaching up to 90%. The power supply therefore converts more energy from the mains into usable power and reduces energy losses in the form of heat. This leads to lower operating temperatures not only for the power supply but for the entire build, while also reducing overall electricity costs.

80 Plus certification on the European market
The 80 Plus certification was created to objectively evaluate the efficiency of PC power supplies. This provides users with a simple and clear way to compare different models. On the European market (where a voltage of 230V is used), there are six levels of 80 Plus certification, each with set requirements for PC power supplies. Higher energy efficiency primarily means lower energy consumption.
| PC power supply load | Efficiency at 20% load | Efficiency at 50% load | Efficiency at 100% load |
|---|---|---|---|
| 80 PLUS | 82% | 85% | 82% |
| 80 PLUS Bronze | 85% | 88% | 85% |
| 80 PLUS Silver | 87% | 90% | 87% |
| 80 PLUS Gold | 90% | 92% | 89% |
| 80 PLUS Platinum | 92% | 94% | 90% |
| 80 PLUS Titanium | 94% | 96% | 94% |
