Gigabyte P750BS 80 Plus Bronze Non Modular 750w Power Supply Unit vs NZXT C850 SFX Gold - 850W SFX ATX 3.1 Power Supply - 80 Plus Gold - Cybenetics P

Price Comparison

When it comes to price, the Gigabyte P750BS offers a more budget-friendly option at £57.55, whereas the NZXT C850 is significantly pricier at £129.98. The difference of £72.43 makes the Gigabyte an appealing choice for those looking to save money without sacrificing essential power supply functions. While the NZXT C850 boasts higher wattage and efficiency ratings, the Gigabyte's 750W capacity is still sufficient for many mid-range builds. If budget constraints are a priority, the Gigabyte P750BS clearly stands out as the economical choice.

Efficiency Ratings

The efficiency rating is a critical factor in power supply performance, and here, the NZXT C850 excels with an 80 PLUS Gold certification. This means it operates at a higher efficiency, reducing wasted energy and heat output. Conversely, the Gigabyte P750BS holds an 80 PLUS Bronze certification, which, while respectable, does not match the premium efficiency of its competitor. The NZXT's advanced efficiency translates to potentially lower electricity bills and a cooler system, making it a better option for users who prioritise energy efficiency and long-term savings.

Power Output

The NZXT C850 offers a robust 850W power output, which is higher than the 750W provided by the Gigabyte P750BS. This additional wattage can be crucial for high-performance setups, particularly those with power-hungry components like top-tier graphics cards. The Gigabyte, while still adequate for many builds, may not support the most demanding systems as comfortably as the NZXT. Thus, for users planning to push their hardware to the limit, the NZXT's superior power output could make a significant difference in performance and stability.

Build Quality and Design

In terms of design, the NZXT C850 is tailored for compact builds, featuring an SFX form factor that optimises space without sacrificing power capabilities. This makes it a compelling choice for small form factor (SFF) cases, where every inch counts. The Gigabyte P750BS, while well-built, follows a more traditional design and lacks the compact advantages of the NZXT. Users aiming for sleek and space-efficient setups will likely prefer the NZXT’s design, which integrates seamlessly into smaller cases.

Cooling Solutions

Cooling is vital for maintaining optimal performance and longevity in power supplies. The NZXT C850 features a 92 mm fluid dynamic bearing (FDB) fan with a Zero RPM mode to ensure silent operation during low loads. This innovative cooling system contributes to a quieter overall build, which can be particularly appealing for users who value a noise-free environment. In contrast, the Gigabyte P750BS has a larger 120mm silent FDB fan, which provides effective cooling but may not match the quiet operation of the NZXT under low-load conditions. Therefore, those who prioritise a quiet system may find the NZXT C850 to be the superior option.

Protection Features

Both power supplies include essential protection features, but the Gigabyte P750BS offers a robust suite that includes OVP, OPP, SCP, UVP, OCP, and OTP protection. This comprehensive protection ensures the safety of your components against various electrical issues. The NZXT C850 also promises reliable power delivery, especially with its ATX 3.1 certification, ensuring compatibility with modern graphics cards. While both units are designed with safety in mind, the Gigabyte's extensive protective features provide added peace of mind for users concerned about hardware longevity.

Target Audience

The target audience for these two power supplies differs significantly based on their specifications. The Gigabyte P750BS caters to budget-conscious consumers or those building mid-range systems, offering a solid balance of performance and affordability. In contrast, the NZXT C850 is aimed at enthusiasts and gamers who require higher power output and efficiency, particularly in compact builds. Users who are keen on investing in premium components and who prioritise performance will find the NZXT a more suitable choice.

Which should you buy?

Ultimately, the decision between the Gigabyte P750BS and the NZXT C850 comes down to your specific requirements. If budget is the primary concern and your system does not demand excessive power, the Gigabyte P750BS offers excellent value at £57.55. However, for those who need higher wattage, better efficiency, and a quieter operation, the NZXT C850, though pricier at £129.98, justifies its cost with advanced features and performance capabilities. Consider your build requirements and budget to determine which power supply aligns best with your needs.
