CORSAIR RM850e vs ESGAMING 700W Non Modular Power Supply with Low-Noise 120mm Fan ATX PSU

Price Comparison

When it comes to price, the ESGAMING 700W Non Modular Power Supply is significantly more affordable than the CORSAIR RM850e, costing C$59.89 compared to C$184.99. This represents a difference of C$125.10, making the ESGAMING option more appealing for budget-conscious consumers. However, it's essential to weigh the price against the features and performance capabilities offered by each power supply. While the ESGAMING may be more accessible financially, the CORSAIR unit boasts advanced specifications that may justify its higher price point for serious gamers and PC builders.

Performance and Power Delivery

In terms of power delivery, the CORSAIR RM850e offers a robust 850 watts, while the ESGAMING provides 700 watts. This difference of 150 watts can have a substantial impact on system performance, particularly for high-end builds that require more power for components such as graphics cards. The CORSAIR’s power supply is also Intel ATX 3.1 certified, ensuring compliance with the latest standards and better stability during power spikes. This certification means it can handle transient power excursions effectively, making it a more reliable choice for demanding gaming setups.

Noise Levels

Noise levels are a critical consideration for many users, and here, the CORSAIR RM850e has a slight edge. It features a 120mm rifle bearing fan designed for low-noise operation, even under full load. The specially calculated fan curve keeps the noise to a minimum, enhancing the overall user experience. On the other hand, the ESGAMING also boasts a large 120mm fan that operates virtually silently at low loads. However, the lack of specific noise measurements means that while it claims quiet operation, the CORSAIR's design appears more tailored for consistent low noise across varying loads.

Cable Management

The CORSAIR RM850e excels in cable management with its fully modular design, allowing users to connect only the cables needed for their system. This feature not only simplifies installation but also helps in maintaining a clean build, improving airflow within the case. In contrast, the ESGAMING uses non-modular cables that come pre-installed, which can lead to excess cables cluttering the system. While the ESGAMING’s cables are designed to avoid the traditional "ketchup and mustard" colour scheme, the flexibility of the CORSAIR's modular setup offers a more customized and tidy approach to cable management.

Build Quality and Components

Build quality is another area where the CORSAIR RM850e stands out. It is equipped with 105°C-rated capacitors, ensuring dependable electrical performance and steady power delivery. This quality is crucial for maintaining longevity and reliability in a power supply, especially under heavy loads. The ESGAMING, while also featuring comprehensive protection mechanisms like OVP and UVP, does not specify the temperature rating of its components. As a result, the CORSAIR may provide better assurance of its durability and performance over time.

Compatibility and Features

The CORSAIR RM850e and ESGAMING 700W power supplies cater to different user needs in terms of compatibility and features. The CORSAIR is fully compatible with the latest Intel ATX 3.1 power standard, which is essential for modern builds that require optimal power delivery. It also supports PCIe 5.1, which is crucial for future-proofing your system. Meanwhile, the ESGAMING offers high compatibility with its standard ATX form factor and various connectors, including the ability to split 8-pin connectors. However, its lack of modularity may limit its appeal to users seeking a more tailored setup.

Safety and Protection Features

Safety features are paramount in power supplies, and both the CORSAIR RM850e and ESGAMING 700W come equipped with protective mechanisms. The CORSAIR includes modern features to ensure safe operation under various conditions, while the ESGAMING provides heavy-duty protections such as OVP, UVP, OPP, SCP, OCP, and OTP. This comprehensive approach to safety in the ESGAMING model offers peace of mind for users concerned about potential electrical issues. However, the CORSAIR's reputation for quality may sway users toward its more premium offering.

Which should you buy?

In conclusion, choosing between the CORSAIR RM850e and the ESGAMING 700W Non Modular Power Supply largely depends on your specific needs and budget. If you are looking for a high-performance, reliable power supply with advanced features and a fully modular design, the CORSAIR RM850e is worth the investment at C$184.99. On the other hand, if you are on a tight budget and need a basic power supply that covers essential functions, the ESGAMING at C$59.89 offers great value. Ultimately, your choice should align with your performance requirements, budget constraints, and preferences regarding features like modularity and noise levels.
