Gigabyte P750BS 80 Plus Bronze Non Modular 750w Power Supply Unit vs NZXT C850 Gold ATX 3.1 - Fully Modular Low-Noise PC Gaming Power Supply - 850 Wa

Introduction to Power Supplies

When it comes to power supplies for your PC, choosing the right model is crucial for ensuring stability and performance. In this comparison, we will explore two distinct power supply units: the Gigabyte P750BS 80 Plus Bronze Non Modular 750w Power Supply Unit and the NZXT C850 Gold ATX 3.1 Fully Modular Low-Noise PC Gaming Power Supply. The former offers a solid performance at a lower price, while the latter boasts advanced features and a higher wattage capacity.

Price Comparison

The Gigabyte P750BS is priced at £57.55, making it an attractive option for budget-conscious consumers. In contrast, the NZXT C850 is considerably more expensive at £84.90. This difference of £27.35 reflects the NZXT's additional features and higher power output, which may be worth the investment for gamers and high-performance users. When considering price, the Gigabyte offers good value, but the NZXT may justify its higher cost with its premium capabilities.

Power Output and Efficiency

The Gigabyte P750BS delivers 750 watts of power, earning an 80 PLUS Bronze certification. This rating indicates a decent level of efficiency, ensuring that it operates effectively without excessive energy waste. Meanwhile, the NZXT C850 provides 850 watts, compliant with the ATX 3.1 standard. This means it not only delivers more power but does so with improved stability and efficiency, particularly under load. For users with high-performance components, the extra 100 watts from the NZXT may be essential for optimal performance.

Design and Build Quality

In terms of design, the Gigabyte P750BS features soft-textured embossed cables and a 120mm Silent Fluid Dynamic Bearing fan. While it is a non-modular unit, which can complicate cable management, its build quality is reliable for standard setups. On the other hand, the NZXT C850 is fully modular, allowing users to connect only the cables they need, promoting better airflow and a neater build. Its construction includes 100% premium Japanese capacitors, enhancing durability and minimising ripple noise. This focus on quality makes the NZXT a standout choice for high-end builds.

Noise Levels

Noise levels are an important consideration, especially for gamers and content creators who require a quiet environment. The Gigabyte P750BS, while designed with a silent fan, does not specify noise levels, leaving some uncertainty regarding its operation under load. Conversely, the NZXT C850 features a 135mm fluid dynamic bearing fan with a Zero Fan Mode, ensuring it operates silently when under 50% load. This feature is particularly beneficial for users who want a whisper-quiet gaming experience, making the NZXT a preferable choice for noise-sensitive environments.

Compatibility and Future-Proofing

The Gigabyte P750BS is equipped with a single +12V rail, which is suitable for most standard components. However, it may not fully support newer high-demand graphics cards. In comparison, the NZXT C850 is designed to be 50 SERIES READY, meaning it can handle the power requirements of NVIDIA's latest graphics cards. This ensures that the NZXT is better equipped for future upgrades, making it a more future-proof investment for those looking to build or upgrade their systems in the coming years.

User Experience and Reliability

Both power supplies are built to provide reliable power delivery, but their user experiences differ. The Gigabyte P750BS is straightforward and caters to users who need a dependable power source without frills. Its protections, including OVP, OPP, SCP, UVP, OCP, and OTP, ensure a level of safety for connected components. On the other hand, the NZXT C850 emphasises a high-quality user experience with its modular design and premium components, which can lead to improved reliability and performance. Users seeking a top-tier experience may find the NZXT more appealing.

Which should you buy?

In conclusion, choosing between the Gigabyte P750BS and the NZXT C850 ultimately depends on your specific needs and budget. The Gigabyte P750BS offers a cost-effective solution with decent efficiency, making it suitable for standard builds. However, if you require more power, advanced features, and a quiet operation, the NZXT C850 justifies its higher price with superior performance and future-proofing capabilities. For gamers and users planning to use high-performance components, the NZXT C850 is the clear winner.
