Corsair RM750e (2025)
The Corsair RM750e (2025) computer power supply, with a total output of 750W, provides stable power for high-performance ATX-based PC builds. Its operation is backed by dual 80 PLUS Gold and Cybenetics Gold certifications, which confirm high energy conversion efficiency and contribute to lower running costs and less heat generation. Full compatibility with ATX 3.1 and PCIe 5.1 standards is key to reliably powering modern-generation components. The PSU's internal layout uses a modern LLC topology with DC-to-DC conversion for precise voltage regulation across all rails.

Key technologies of the Corsair RM750e (2025) computer power supply
- 80 PLUS Gold certification confirms energy conversion efficiency
- Fully modular cabling system simplifies installation
- Native 12V-2x6 connector powers modern graphics cards
- Zero RPM mode stops the fan under low load
- Internal components include high-temperature-rated capacitors
- Compact size for easy installation in cases
Choosing a power supply
When choosing a suitable PC power supply, the key parameter, besides the form factor, 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 determine the optimal wattage based on your chosen components.
Compact dimensions and ATX 3.1 standard
With a depth of just 140 millimetres, this power supply fits into most modern ATX computer cases, including smaller models. Its compact size makes installation easier, even in cases with limited space for cable management. Full certification for the ATX 3.1 standard confirms that the PSU can handle the high, sudden power spikes typical of powerful graphics cards and processors. The power supply delivers stable and consistent power even under extreme load, which contributes to overall system stability. Support for this standard is essential for builds with power-hungry components.
Fully modular cabling and quiet operation
The fully modular cabling system significantly simplifies installation and cable management inside the computer case. This results in a cleaner interior and better airflow, which helps cool the processor and graphics card more effectively. A 120mm rifle bearing fan with thermal speed control cools the internal components. Its speed automatically adjusts to the current load and the internal temperature of the PSU based on a specifically calculated curve. The Zero RPM function keeps the fan completely off under low to medium loads, leading to near-silent operation during everyday office work or web browsing. The fan only activates when power draw increases.
Native PCIe 5.1 connector
The power supply includes a native 16-pin 12V-2x6 connector, which complies with the PCIe 5.1 specification and is used to power energy-intensive graphics cards. This output delivers power directly, without the need for transitional adapters, which can be a source of contact issues. The direct connection reduces the risk of incorrect wiring and contributes to a cleaner, more reliable cable arrangement in your PC build.
Internal topology and reliable components
The internal design is based on a resonant LLC topology with DC-to-DC conversion. This technical solution contributes to high efficiency and precise voltage regulation across all output rails. The main +12V rail is therefore stable, while the PSU generates the +5V and +3.3V rails with minimal losses. The use of industrial-grade capacitors rated for 105°C supports the reliability and long-term stability of the power supply, even under heavy use and at higher ambient temperatures.
Modern Standby support
The power supply supports Modern Standby sleep mode, a standard feature in Windows operating systems. This mode keeps the network connection active even with very low power consumption, resulting in almost instant wake-up times. Your computer wakes from sleep much faster than with older sleep modes. It also immediately synchronises data in the background.

80 Plus certification on the European market
The 80 Plus certification was created to objectively assess the efficiency of computer power supplies. This 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 with set requirements for 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% |
