be quiet! Pure Power 13 M 1000W Power Supply vs CORSAIR RM750e

Price Comparison

The be quiet! Pure Power 13 M 1000W Power Supply is priced at £99.99, making it the more expensive option compared to the CORSAIR RM750e, which retails for £81.99. This price difference of £18 may reflect the additional wattage and features of the be quiet! model. While the higher cost of the be quiet! unit can be justified by its 1000W power capacity, which is suitable for high-performance gaming and workstation builds, the RM750e offers a solid performance at a lower price point. For users with less demanding power needs, the lower price of the RM750e may prove to be more appealing.

Power Capacity

In terms of power output, the be quiet! Pure Power 13 M offers a substantial 1000W, which is ideal for high-end gaming rigs and systems with multiple GPUs. In contrast, the CORSAIR RM750e provides a maximum of 750W. This difference of 250W is significant for users planning to run power-hungry components, especially in gaming or content creation scenarios. If your system requires extensive power, the be quiet! model stands out as the better choice, whereas the RM750e may suffice for mid-range builds without demanding components.

Efficiency Rating

The efficiency of a power supply is critical for both performance and energy costs. The be quiet! Pure Power 13 M boasts an 80 PLUS Gold certification, with an impressive efficiency rating of up to 94.4%. This means it wastes less energy as heat, leading to lower electricity bills and cooler operation. On the other hand, the CORSAIR RM750e, while also compliant with the ATX 3.1 power standard, does not specify its efficiency rating in the provided data. However, Corsair is known for reliable units, and the RM750e likely maintains a good efficiency level. For users who prioritise energy savings and a cooler system, the be quiet! model is clearly superior.

Noise Levels

When it comes to noise output, both power supplies have features aimed at maintaining a quiet operation. The be quiet! Pure Power 13 M integrates a fan that turns off under low load, ensuring silent operation during less demanding tasks. This is further complemented by its airflow-optimised fan blades, designed for minimal noise. The RM750e also features a 120mm rifle bearing fan that operates quietly even under full load. While both units promise low noise, the be quiet! model appears to have a slight edge with its complete fan shutdown feature, making it an excellent choice for quiet systems.

Modular Design

Modularity can greatly enhance the ease of installation and cable management in a PC build. The be quiet! Pure Power 13 M has a modular design that allows users to only connect the cables they need, leading to a more organised and tidy setup. Similarly, the CORSAIR RM750e is fully modular, allowing for selective cable connection that can help in reducing clutter. Both models excel in this area, making either a good choice for users who value a clean build, yet the be quiet! model’s focus on simplicity may be more attractive for those who prioritise aesthetics and airflow.

Compatibility with Next-Gen Components

For those looking to build or upgrade to the latest hardware, compatibility with next-gen components is essential. The be quiet! Pure Power 13 M is designed with native integration of the 12V-2x6 connector, specifically catering to next-generation PCIe 5.1 graphics cards. This feature ensures that it can handle the power demands of the latest GPUs without issue. The CORSAIR RM750e is also Intel ATX 3.1 certified, which enables it to support PCIe 5.1 and withstand transient power excursions from the GPU. Both power supplies are future-proofed for modern systems, but the be quiet! may have a slight advantage with its dedicated connector.

Reliability and Build Quality

Both brands are well-respected in the power supply market, known for their reliability and quality. The be quiet! Pure Power 13 M features an LLC topology that provides excellent voltage regulation and efficiency, which is crucial for stable system performance. In addition, the use of high-quality components ensures durability and longevity. The CORSAIR RM750e, equipped with 105°C-rated capacitors, promises steady and reliable power delivery. While both units are built to last, the emphasis on efficiency and performance in the be quiet! model may appeal more to enthusiasts who demand high reliability under load.

Which should you buy?

Choosing between the be quiet! Pure Power 13 M 1000W Power Supply and the CORSAIR RM750e largely depends on your specific needs. If your system demands high wattage, prioritises quiet operation, and you value efficiency, the be quiet! model is the standout choice at £99.99. However, if you are looking for a reliable power supply for a mid-range build and want to save some money, the CORSAIR RM750e is a fantastic option at £81.99. Ultimately, both power supplies offer great features, but the decision comes down to the balance of power requirements, budget, and personal preference.
