Gigabyte P750BS 80 Plus Bronze Non Modular 750w Power Supply Unit vs CORSAIR RM1200x SHIFT Fully Modular ATX Power Supply - 80 PLUS Gold - ATX 3.1 -

Introduction

When it comes to selecting a power supply unit (PSU), the choice between the Gigabyte P750BS and the Corsair RM1200x SHIFT is significant. The former is priced at £57.55, while the latter is considerably more expensive at £174.98. This price difference hints at distinct features and performance levels that cater to different user needs.

Design and Build Quality

The design of the Gigabyte P750BS focuses on simplicity and efficiency, featuring soft-textured embossed cables. In contrast, the Corsair RM1200x SHIFT boasts an innovative side-access connection position, which facilitates easier cable management. This design choice not only enhances aesthetics but also improves accessibility. Additionally, while the Gigabyte model is non-modular, the Corsair is fully modular with micro-fit connectors, allowing users to connect only the cables they require. This modularity can lead to a cleaner and more organised build.

Efficiency and Certification

The Gigabyte P750BS holds an 80 PLUS Bronze certification, indicating a decent efficiency level at 230V. This certification suggests that it operates at a minimum efficiency of 82% under typical loads. On the other hand, the Corsair RM1200x SHIFT is certified 80 PLUS Gold, guaranteeing higher efficiency levels of at least 87% at similar loads. This higher efficiency translates to reduced energy costs over time, making the Corsair a more sustainable choice for long-term use.

Cooling Performance

Cooling capabilities are crucial in maintaining optimal operation for any PSU. The Gigabyte P750BS is equipped with a 120mm silent fluid dynamic bearing fan, designed for quieter performance. Conversely, the Corsair RM1200x SHIFT features a larger 140mm fluid dynamic bearing fan, which utilises a specially calculated fan curve for high performance and low noise. This difference in fan size and design can significantly impact thermal performance, particularly in high-demand scenarios, making the Corsair potentially more reliable under load.

Internal Components

When evaluating the internal components, the Gigabyte P750BS offers standard protections such as OVP, OPP, SCP, UVP, OCP, and OTP. While these features are essential for basic safety, the Corsair RM1200x SHIFT goes a step further with 100% 105°C-rated Japanese electrolytic capacitors. These premium components contribute to unwavering power delivery and enhance the long-term reliability of the PSU. The quality of internal components can significantly affect the lifespan and performance consistency of the power supply.

Compatibility and Standards

The Corsair RM1200x SHIFT is Intel ATX 3.1 certified, ensuring compliance with the latest power standards and support for the PCIe Gen 5.1 platform. This certification is particularly relevant for users looking to build high-performance systems that require the latest technology. In comparison, the Gigabyte P750BS does not specify compliance with such advanced standards, making it more suitable for standard builds or less demanding applications.

Price and Value Proposition

At £57.55, the Gigabyte P750BS is an attractive option for budget-conscious consumers seeking reliable power without breaking the bank. However, the Corsair RM1200x SHIFT, priced at £174.98, offers advanced features, higher efficiency, and superior build quality that may justify its cost for those requiring top-tier performance. The price difference of £117.43 reflects not only the features but also the long-term value and reliability that could make the Corsair worth the investment for serious gamers or professionals.

User Experience and Support

User experience can be an important factor when choosing a power supply. The Gigabyte P750BS presents a straightforward setup, ideal for users who prefer simplicity. Meanwhile, the Corsair RM1200x SHIFT’s fully modular design allows for tailored connectivity, which can enhance the overall building experience, especially for those who value aesthetics and organisation. Moreover, Corsair is known for its robust customer support, which can be a significant advantage for users who may need assistance or warranty claims.

Which should you buy?

Choosing between the Gigabyte P750BS and the Corsair RM1200x SHIFT ultimately depends on your specific needs and budget. If you're seeking a budget-friendly, reliable PSU for a standard build, the Gigabyte P750BS is a solid choice. However, for those looking for high efficiency, advanced features, and better long-term reliability, the Corsair RM1200x SHIFT justifies its higher price. Evaluate your requirements carefully to make the best decision for your system.
