Gigabyte P750BS 80 Plus Bronze Non Modular 750w Power Supply Unit vs Corsair RM850e

Price Comparison

When it comes to pricing, the Gigabyte P750BS is significantly more affordable than the Corsair RM850e, with a current price of £57.55 compared to £92.99. This represents a difference of £35.44, making the Gigabyte option an appealing choice for budget-conscious consumers. While the lower price of the Gigabyte power supply may suggest a compromise in features or performance, it is important to examine what each unit has to offer for the cost. The pricing difference could be a decisive factor for users looking to build a cost-effective system without significantly sacrificing quality.

Power Output and Efficiency

The Gigabyte P750BS offers a power output of 750 watts, which is suitable for many mid-range to high-end gaming systems. It is 80 PLUS Bronze certified, ensuring a reasonable level of energy efficiency. In contrast, the Corsair RM850e provides an 850-watt output and is Intel ATX 3.1 certified, indicating not only compliance with the latest power standards but also support for high-performance components, including PCIe Gen 5.1. The additional wattage of the Corsair unit could allow for a more powerful setup, particularly advantageous for users who plan to overclock or run multiple GPUs.

Build Quality and Design

The design of each power supply reflects its brand's commitment to quality. The Gigabyte P750BS features soft-textured embossed cables and a 120mm silent fluid dynamic bearing fan, aimed at reducing noise during operation. Meanwhile, the Corsair RM850e boasts fully modular cabling, enabling users to connect only the cables necessary for their build, thus enhancing airflow and aesthetics. The RM850e also utilises 105°C-rated capacitors, which are designed to deliver steady, reliable power and improve overall electrical performance. This attention to quality in component selection may contribute to the Corsair's higher price point.

Noise Levels

Noise levels are a crucial consideration for users who prioritise a quiet computing environment. The Gigabyte P750BS is equipped with a 120mm silent fluid dynamic bearing fan, which helps minimise noise during operation, although specific decibel ratings are not mentioned. On the other hand, the Corsair RM850e features a rifle bearing fan with a specially calculated fan curve, designed to keep noise down even under full load. For users who require a quieter system, the design of the Corsair's fan may offer a tangible benefit over the Gigabyte model, which, while silent, may not perform as well under heavy stress.

Protection Features

In terms of safety and protection features, both power supplies offer essential safeguards, but they differ in the breadth of their protections. The Gigabyte P750BS includes a range of protections such as Over Voltage Protection (OVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Under Voltage Protection (UVP), Over Current Protection (OCP), and Over Temperature Protection (OTP). This comprehensive suite of protections ensures reliable operation. The Corsair RM850e, while also providing robust protection, does not detail these specific safety features in the same depth. Users seeking peace of mind may find the extensive protections of the Gigabyte unit particularly reassuring.

Compatibility and Future-Proofing

Compatibility is another critical factor when choosing a power supply. The Gigabyte P750BS is designed for standard builds and supports a variety of components, but it may not be as future-proof as the Corsair RM850e. The RM850e is compliant with the ATX 3.1 power standard, making it suitable for the latest hardware, including support for PCIe Gen 5.1. This compliance could be a decisive factor for gamers and professionals looking to invest in cutting-edge technology. If future compatibility is a primary concern, the Corsair RM850e’s certifications could make it the better option.

User Experience and Installation

User experience often hinges on how easy it is to install and use a power supply. The Gigabyte P750BS, being a non-modular power supply, may require a bit more effort during installation as all cables are fixed, which could lead to a cluttered case if not managed properly. In contrast, the Corsair RM850e’s fully modular design allows for greater flexibility, allowing users to connect only the cables they need. This modularity not only simplifies installation but also aids in maintaining a clean and efficient build, making it an attractive option for those who value ease of assembly and organisation.

Which should you buy?

In summary, the choice between the Gigabyte P750BS and the Corsair RM850e ultimately depends on individual needs and budget. The Gigabyte P750BS is a solid, budget-friendly option with good protections and efficient performance for its price. However, for users seeking higher wattage, future-proofing, and a modular design, the Corsair RM850e is worth the investment, despite its higher cost. Each power supply has its strengths, and consumers should consider their unique requirements when making a decision.
