Gigabyte P750BS 80 Plus Bronze Non Modular 750w Power Supply Unit vs CORSAIR RM650e

Overview of the Gigabyte P750BS and Corsair RM650e

The Gigabyte P750BS and Corsair RM650e are both reliable power supply units catering to different needs. Priced at £57.55, the Gigabyte offers a robust 750W capacity, while the Corsair, at £71.57, provides a slightly lower power output of 650W. This comparison will delve into their features, performance, and value to help you decide which unit suits your system best.

Power Output and Efficiency

When it comes to power output, the Gigabyte P750BS stands out with its 750W capacity, making it suitable for high-performance builds that may require more power. It is 80 PLUS Bronze certified, ensuring a decent level of efficiency at various load levels. In contrast, the Corsair RM650e, with a 650W output, is also efficient but may limit more demanding systems. While both units are reliable, the Gigabyte's higher wattage could be more beneficial for gamers or professionals using power-intensive components.

Modular Design

The modularity of a power supply can significantly impact cable management and airflow within your case. The Corsair RM650e features a fully modular design, allowing users to connect only the cables they need, which can lead to a cleaner build and improved airflow. On the other hand, the Gigabyte P750BS is a non-modular unit, meaning all cables are fixed. This design can create a more cluttered environment and may not be as aesthetically pleasing for those who value cable management.

Noise Levels

In terms of noise performance, the Corsair RM650e has an edge due to its 120mm rifle bearing fan and specially calculated fan curve, designed to keep noise levels low, even under full load. The Gigabyte P750BS also employs a 120mm fan, but it lacks the advanced noise reduction features of the Corsair. Users who prioritise a quiet computing experience might prefer the Corsair for its superior noise management.

Build Quality and Components

Build quality is paramount in power supplies, and both brands are known for their reliability. The Corsair RM650e is built with 105°C-rated capacitors, ensuring it delivers steady and reliable power over time. While the Gigabyte P750BS also boasts high-quality components, it does not specify the rating of its capacitors. This detail may provide the Corsair with an advantage in terms of long-term durability and performance consistency.

Compatibility and Standards

In terms of compatibility, the Corsair RM650e is Intel ATX 3.1 certified, which allows it to support the latest power standards, including PCIe 5.1. This certification means it can efficiently handle transient power excursions, particularly useful for high-end GPUs. The Gigabyte P750BS does not mention compliance with such a standard, which may limit its compatibility with the latest hardware advancements in the market.

Protection Features

Both power supplies come equipped with essential protection features to safeguard your components. The Gigabyte P750BS includes OVP, OPP, SCP, UVP, OCP, and OTP protections, ensuring your system is protected against overvoltage, overcurrent, and other potential electrical issues. Similarly, while specific protection features for the Corsair RM650e are not detailed, its build quality and certifications suggest it also provides essential protections. However, the explicit listing of features gives the Gigabyte an advantage in terms of reassurance for potential buyers.

Price and Value

The Gigabyte P750BS is priced at £57.55, making it a more budget-friendly option for those seeking a reliable power supply without breaking the bank. The Corsair RM650e, at £71.57, is a higher investment but provides additional features such as full modularity and advanced noise control. Ultimately, the choice between them may depend on your specific needs and budget constraints, with the Gigabyte appealing to those looking for more wattage at a lower price.

Which should you buy?

Choosing between the Gigabyte P750BS and Corsair RM650e depends on your specific requirements. If you need a higher wattage and are on a budget, the Gigabyte P750BS is an excellent choice. However, if you value modularity, quieter operation, and compliance with the latest standards, the Corsair RM650e may justify its higher price. Ultimately, both power supplies offer solid performance, but your choice should align with your build's requirements and your preferences for features.
