Key technologies of the Corsair RM1000e White computer power supply
- 80 PLUS Gold certification confirms high energy conversion efficiency
- Fully modular cabling reduces case clutter and improves airflow
- Zero RPM mode turns the fan off under low load to reduce noise
- 12V-2x6 connector directly supplies modern graphics cards with high power
- Compact depth makes installation easier in smaller cases
- Capacitors are rated to withstand 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 its format is its wattage. This indicates the maximum number of watts the power supply can continuously deliver to the computer's components. It's a good idea to use an online calculator to work out the optimal wattage 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 brief but 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 adaptors, 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 of the computer power supply
Cooling is handled by a 120mm fan with a rifle bearing and a specially calculated fan curve that minimises operational noise. With Zero RPM mode, the fan stops completely under low to medium loads, and the power supply operates in a passive, silent mode. It only activates when power draw increases, maintaining a quiet environment during everyday tasks 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 computer cases. More 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 of the power supply
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 capacitors rated for 105°C, which contribute to long-term reliability and consistent performance even under high and sustained loads. Support for Modern Standby mode shortens the system's wake-up time from sleep mode.
Fully modular cabling system
The fully modular design lets you connect only the cables that are 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, resulting in neater cable management and a cleaner final look for your build.
High efficiency computer power supply
The 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 system, while also reducing overall electricity costs.

80 Plus certification on the European market
80 Plus certification was created to objectively evaluate the efficiency of PC power supplies. It gives users a simple and clear way to compare different models. On the European market (where 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 % |
