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

Price Comparison

The Gigabyte P750BS is priced at £57.55, while the NZXT C850 Gold Core retails for £89.99, making it £32.44 more expensive. This significant price difference could be a deciding factor for budget-conscious consumers. The Gigabyte power supply offers a solid foundation for users seeking reliable performance at a lower cost, whereas the NZXT model, with its higher price, promises advanced features and efficiency, appealing to those who may be willing to invest more for premium performance.

Efficiency Ratings

The Gigabyte P750BS boasts an 80 PLUS Bronze certification, indicating a decent level of efficiency with up to 85% energy use at 50% load. In contrast, the NZXT C850 Gold Core is rated 80 PLUS Gold, providing energy efficiency of up to 90% at the same load. This higher efficiency rating suggests that the NZXT unit is better suited for power-intensive applications, reducing overall power consumption and heat generation. For users who prioritise energy savings and operational costs, the NZXT model may be the more attractive choice.

Cooling Solutions

Cooling is crucial for maintaining optimal performance in power supplies. The Gigabyte P750BS features a 120mm Silent Fluid Dynamic Bearing fan, designed to operate quietly while effectively dissipating heat. The NZXT C850 Gold Core takes cooling a step further with a 135mm fluid dynamic bearing fan that includes a Zero RPM mode, ensuring silent operation during light workloads. The quieter performance of the NZXT model, particularly under low loads, may appeal to users looking for a silent computing environment, especially in home or office settings.

Compatibility with Modern GPUs

When it comes to compatibility, the NZXT C850 Gold Core is ATX 3.1 certified and PCIE 5.1 ready, making it ideal for modern GPUs, including those from NVIDIA. It features a dual-colour 12V-2x6 connector and supports up to three 8-pin PCIe cables, ensuring versatility for high-end graphics cards. The Gigabyte P750BS, while reliable, does not offer the same level of cutting-edge compatibility. For gamers and professionals using the latest graphics technology, the NZXT’s superior compatibility could be a critical factor.

Build Quality and Design

Both power supplies reflect a commitment to build quality, but they cater to different aesthetics and user preferences. The Gigabyte P750BS showcases soft-textured embossed cables, contributing to a clean and tidy build. Conversely, the NZXT C850 Gold Core, with its sleek design and premium materials, is likely to appeal to users who prioritise aesthetics and a modern look in their builds. The choice between these designs may come down to personal taste and the overall aesthetic of the user's system.

Protection Features

Protection features are essential for ensuring the longevity and safety of components. The Gigabyte P750BS comes with several protections, including 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). The NZXT C850 Gold Core does not list specific protection features, but its high efficiency and cooling capabilities imply a robust design. The comprehensive protection offered by the Gigabyte unit provides peace of mind, particularly for those concerned about safeguarding their hardware investment.

Noise Levels

In terms of noise, the NZXT C850 Gold Core is Cybenetics noise certified for near-silent performance, achieving an A++ rating at under 15 dBA, which is impressive for a power supply. The Gigabyte P750BS, while also designed for quiet operation, does not specify a noise rating. This distinction gives the NZXT model a clear advantage for users who require a quiet environment, as the NZXT's operation is specifically engineered to minimise noise, making it ideal for gaming and content creation setups where silence is golden.

Which should you buy?

Choosing between the Gigabyte P750BS and the NZXT C850 Gold Core ultimately hinges on your specific needs and budget. The Gigabyte model offers excellent value for money with its reliable performance and lower price of £57.55, making it a solid choice for budget-conscious users. However, if you're looking for higher efficiency, superior cooling options, and compatibility with modern GPUs, the NZXT C850 Gold Core, priced at £89.99, justifies its higher cost with advanced features and near-silent operation. Thus, your decision should align with your priorities—whether that be budget constraints or the pursuit of cutting-edge technology.
