CORSAIR RM750e vs be quiet! System Power 11 750W Power Supply

Price Comparison

When comparing the prices of CORSAIR RM750e and be quiet! System Power 11 750W, the latter is the more economical choice at £64.99, whereas the former costs £81.99. This difference of £17 translates to a 26% higher price for the CORSAIR model. For budget-conscious consumers or those looking to maximise their value, the be quiet! power supply presents a more attractive option without compromising on essential features.

Power Output and Efficiency

Both the CORSAIR RM750e and be quiet! System Power 11 offer a robust power output of 750W. However, the be quiet! unit boasts an 80 PLUS Bronze certification, reflecting an efficiency rating of up to 90%. This certification indicates that it can convert more of the power drawn from the wall into usable power for your components. In contrast, while the CORSAIR also supports various high-demand scenarios, it does not specify an efficiency rating in the provided data, making the be quiet! a more efficient choice on paper for those concerned about energy consumption.

Build Quality and Components

The CORSAIR RM750e features 105°C-rated capacitors, which are designed to deliver steady and reliable power under demanding conditions, ensuring dependable electrical performance. On the other hand, the be quiet! System Power 11 is equipped with a temperature-controlled 120mm fan, known for its low noise levels, which aligns with the brand’s reputation for quiet operation. While both power supplies highlight quality components, the specific mention of higher-rated capacitors in the CORSAIR model may suggest a slight edge in reliability and longevity.

Modular Design

The CORSAIR RM750e is fully modular, allowing users to connect only the cables they need, thereby reducing clutter and improving airflow within the case. This design not only facilitates a cleaner build but also enhances ease of installation. Conversely, the be quiet! System Power 11 does not mention a fully modular design, which may lead to a less flexible cable management experience. For users prioritising aesthetics and airflow, the CORSAIR RM750e stands out with its modularity.

Compatibility with Next-Gen Components

Both power supplies are compatible with modern hardware, including support for PCIe 5.1 graphics cards. The CORSAIR RM750e is compliant with the Intel ATX 3.1 power standard, ensuring it can withstand transient power excursions from GPUs. Similarly, the be quiet! System Power 11 features native integration of the 12V-2x6 connector specifically designed for next-generation GPUs. This dual compatibility makes both products future-proof; however, the CORSAIR’s additional standard compliance may offer extra peace of mind for users looking to build high-performance systems.

Noise Levels

In terms of noise performance, both power supplies feature a 120mm fan designed to operate quietly. The CORSAIR RM750e utilises a specially calculated fan curve to minimise noise, even under full load. The be quiet! System Power 11, true to its brand name, emphasises low noise operation, which has become synonymous with its power supplies. While both models are designed for quiet operation, the CORSAIR’s specific fan design may offer a slight advantage in maintaining lower noise levels during demanding tasks.

Safety Features

Safety is a critical consideration for any power supply, and both the CORSAIR RM750e and be quiet! System Power 11 excel in this area. The CORSAIR model features reliable protection mechanisms but does not specify them in the data provided. Meanwhile, the be quiet! System Power 11 lists multiple safety protections against overcurrents, over- and undervoltages, overtemperature, short circuits, and overloads. This comprehensive safety suite ensures that users can trust their components are well-protected, making the be quiet! a more reassuring option for those concerned about potential electrical issues.

Which should you buy?

In concluding the comparison between the CORSAIR RM750e and be quiet! System Power 11 750W, the choice largely depends on your specific needs. The be quiet! offers a more budget-friendly price point at £64.99 with solid efficiency and safety features, making it suitable for users looking for value without sacrificing performance. On the other hand, the CORSAIR RM750e, priced at £81.99, provides modularity and potentially superior component quality, appealing to those who prioritise system aesthetics and long-term reliability. Ultimately, if you value modularity and are willing to invest more for it, the CORSAIR may be the right choice; however, for most users, the be quiet! System Power 11 presents an excellent balance of performance and price.
