CORSAIR RM750e vs Gigabyte P750BS 80 Plus Bronze Non Modular 750w Power Supply Unit

Overview of the Power Supplies

When comparing the CORSAIR RM750e and the Gigabyte P750BS, the key difference lies in modularity and certification. The CORSAIR RM750e is a fully modular power supply, priced at £81.99, while the Gigabyte P750BS is a non-modular unit available for £65.01. This variance in design and functionality heavily influences usability and installation flexibility for system builders.

The modularity of the CORSAIR RM750e allows users to connect only the cables they need, reducing clutter and improving airflow within the case. In contrast, the Gigabyte P750BS’s non-modular design means all cables are permanently attached, which may lead to excess cabling if not all connections are required.

Certification and Efficiency

The CORSAIR RM750e boasts an Intel ATX 3.1 certification, ensuring it meets higher standards of efficiency and power delivery. In contrast, the Gigabyte P750BS holds an 80 PLUS Bronze certification, indicating it is slightly less efficient but still meets good performance standards.

This distinction is significant for those aiming for systems with high performance and stability under load, as the CORSAIR's capabilities include support for PCIe 5.1 and resilience against transient power excursions. The Gigabyte, while competent, may not handle extreme demands as effectively due to its lower certification level.

Cooling Solutions

Cooling performance is another area where these two power supplies diverge. The CORSAIR RM750e is equipped with a 120mm rifle bearing fan designed to operate quietly, even under full load. This is particularly beneficial for users who prioritise a silent build, as it keeps fan noise to a minimum.

On the other hand, the Gigabyte P750BS utilises a 120mm silent fluid dynamic bearing fan. While it also focuses on quiet operation, the specifics of the fan technology in the CORSAIR unit may provide a slight edge in noise reduction during intense usage scenarios.

Build Quality and Components

The build quality of a power supply is crucial for long-term reliability. The CORSAIR RM750e features 105°C-rated capacitors, which are essential for ensuring steady and reliable power delivery. This higher thermal rating allows the PSU to operate safely even under demanding conditions.

Conversely, while the Gigabyte P750BS is built with quality in mind, it does not specifically highlight the ratings of its capacitors. The absence of such specifications might lead to questions regarding its long-term durability compared to the CORSAIR.

User Experience and Installation

User experience can greatly influence the overall satisfaction with a power supply. The CORSAIR RM750e’s fully modular design translates to a more streamlined and flexible installation process. Users can customise the cabling according to their needs, making it easier to manage and organise within the chassis.

In comparison, the Gigabyte P750BS’s non-modular approach might complicate installations for users who prefer a tidy setup. The permanently attached cables can create unnecessary clutter, especially in smaller cases, potentially affecting airflow and aesthetics.

Safety Features and Protection

Both power supplies come with essential safety features to protect the system from electrical issues. The CORSAIR RM750e is designed with modern standards in mind, but specific features such as over-voltage protection (OVP) and under-voltage protection (UVP) are not explicitly mentioned.

The Gigabyte P750BS, however, lists several protections including OVP, over-power protection (OPP), short-circuit protection (SCP), under-voltage protection (UVP), over-current protection (OCP), and over-temperature protection (OTP). This comprehensive safety suite makes it a reliable choice for users concerned about potential electrical failures.

Price Comparison

Pricing is a notable factor when evaluating these two power supplies. The CORSAIR RM750e is available for £81.99, while the Gigabyte P750BS is priced more affordably at £65.01. This £16.98 difference reflects the added features and benefits of the CORSAIR, such as modularity and higher efficiency certifications.

For budget-conscious users, the Gigabyte P750BS presents a compelling option, particularly for mid-range builds. However, those who value the advantages of a fully modular design and enhanced efficiency may find the additional investment in the CORSAIR worth it.

Which should you buy?

Ultimately, the choice between the CORSAIR RM750e and the Gigabyte P750BS hinges on individual needs and priorities. If you seek a power supply that offers modularity, superior efficiency, and quieter operation, the CORSAIR RM750e, priced at £81.99, is the better choice. However, for users on a tighter budget who still require a reliable power source, the Gigabyte P750BS at £65.01 provides solid performance with essential safety features. The decision should align with your specific requirements, whether that be performance, budget, or ease of installation.
