CORSAIR SF850 vs Gigabyte P750BS 80 Plus Bronze Non Modular 750w Power Supply Unit

Price Comparison

When it comes to price, the Gigabyte P750BS is significantly more affordable than the CORSAIR SF850. The GIGABYTE unit is priced at £57.55, while the CORSAIR model costs £149.99. This difference of £92.44 highlights the budget-friendly nature of the Gigabyte option, which may appeal to users looking to build a cost-effective system. In contrast, the higher price of the CORSAIR SF850 reflects its premium features and performance capabilities, making it more suitable for high-end builds or users who require top-tier power delivery.

Power Rating and Efficiency

The CORSAIR SF850 boasts an impressive 80 PLUS Platinum certification, which indicates superior energy efficiency compared to the Gigabyte P750BS, which is rated at 80 PLUS Bronze. Platinum-rated power supplies like the CORSAIR model deliver up to 90% efficiency under typical loads, while Bronze-rated units are generally around 82%. This means that while the CORSAIR may have a higher upfront cost, it could lead to lower electricity bills over time due to its efficient power usage, making it an investment for long-term savings.

Form Factor and Compatibility

The CORSAIR SF850 is designed in a compact SFX form factor, catering specifically to small-form-factor PC builds. Its full modular design allows for flexible cabling, which not only optimises space but also enhances cable management within cases. On the other hand, the Gigabyte P750BS is a non-modular unit, which can lead to a cluttered build due to unnecessary cables. Users with limited space will find the CORSAIR model more suitable, while those with standard ATX cases may not feel as constrained by the Gigabyte’s larger design.

Cooling and Noise Levels

In terms of cooling, the CORSAIR SF850 features a 92mm PWM cooling fan that promises low-noise operation due to its fluid dynamic bearing design. This allows it to maintain an efficient cooling profile while keeping noise levels to a minimum, making it ideal for quiet builds. Conversely, the Gigabyte P750BS is equipped with a 120mm silent fluid dynamic bearing fan. While it also aims to operate quietly, the larger fan could potentially produce different sound dynamics under load. Ultimately, both units prioritise cooling efficiency, but the CORSAIR’s design is tailored for smaller cases where sound can be more pronounced.

Build Quality and Components

The build quality of the CORSAIR SF850 is enhanced by the use of 105°C rated Japanese capacitors, which contribute to its reliability and performance under high-stress conditions. This level of component quality is geared towards users who demand consistent power delivery during intensive tasks. In contrast, the Gigabyte P750BS focuses on solid functionality with advanced protection features such as OVP, OPP, SCP, UVP, OCP, and OTP. While both units are designed for durability, the premium components in the CORSAIR may appeal more to enthusiasts or professional users seeking longevity and stability.

Protection Features

Both power supplies come equipped with essential protection features, but they differ in their offerings. The Gigabyte P750BS includes various protections such as Over Voltage Protection (OVP) and Over Temperature Protection (OTP), ensuring safe operation. The CORSAIR SF850, while not explicitly listing the same types of protection, is designed to comply with the ATX 3.1 power standard, which includes safeguards against transient power spikes. Users who prioritise comprehensive protection may find the added assurances of the Gigabyte unit appealing, especially for mid-range builds.

Target Audience

The target audience for the CORSAIR SF850 largely consists of gamers and professionals who require a high-performance power supply for demanding applications. Its high price and premium features reflect the needs of users who build compact, high-performance systems. On the other hand, the Gigabyte P750BS appeals to budget-conscious consumers or casual users who need a reliable power supply for standard gaming or office setups. Each product serves its intended market well, but the choice hinges on what level of performance and features the user desires.

Which should you buy?

Deciding between the CORSAIR SF850 and the Gigabyte P750BS hinges on your specific needs and budget. If you are looking for a high-efficiency, compact power supply with premium features, the CORSAIR SF850, priced at £149.99, is the clear winner. However, if you are on a tighter budget, the Gigabyte P750BS at £57.55 offers solid performance and reliability for more general use. Ultimately, your choice should reflect the balance between your budget and the performance requirements of your system.
