NZXT C850 Gold Core - 850W ATX 3.1 Power Supply - 80 PLUS Gold - Cybenetics Plat vs GIGABYTE P550SS Power Supply - PCIe 5.0

Price Comparison

The NZXT C850 Gold Core is priced at £89.99, significantly higher than the GIGABYTE P550SS, which retails for £40.99. This price difference of £49 reflects the distinct features and capabilities of each power supply. While the GIGABYTE model offers a more budget-friendly option, the NZXT unit justifies its premium with advanced specifications and higher efficiency ratings. Customers seeking a basic power supply may find the GIGABYTE suitable, but those looking for superior performance and efficiency might be inclined to invest in the NZXT.

Efficiency Ratings

When considering efficiency, the NZXT C850 Gold Core stands out with its 80 PLUS Gold and Cybenetics Platinum ratings. This level of efficiency ensures that it delivers energy-efficient performance, reducing both heat output and power consumption under demanding loads. In contrast, the GIGABYTE P550SS is rated 80 PLUS Silver, which, while still respectable, does not match the energy-saving capabilities of the NZXT. The difference in efficiency ratings can lead to noticeable variations in energy costs over time, making the NZXT a more financially sound choice in the long run for those who value energy efficiency.

Compatibility and Future-Proofing

The NZXT C850 Gold Core boasts compatibility with next-gen GPUs, featuring a dual-colour 12V-2x6 connector and support for modern NVIDIA graphics cards, making it ideal for gaming enthusiasts and those building high-performance rigs. Additionally, it is ready for AMD GPUs with the ability to connect up to three 8-pin PCIe cables. On the other hand, the GIGABYTE P550SS supports the Intel ATX 3.0 standard and is compatible with ATX 3.1, which is adequate for many current builds but may not offer the same level of future-proofing as the NZXT. This makes the NZXT a more attractive option for those looking to invest in a power supply that can accommodate future upgrades.

Noise Levels

In terms of noise levels, the NZXT C850 Gold Core excels with its Cybenetics noise certification, achieving a near-silent operation rated at less than 15 dBA under typical workloads. This is particularly advantageous for users who prioritise quiet computing environments. The GIGABYTE P550SS features a 120mm Fluid Dynamic Bearing fan, which also contributes to quiet operation, but lacks specific noise ratings. For users sensitive to sound, the NZXT's superior noise performance may be a compelling factor in their purchasing decision.

Build Quality and Design

Both power supplies showcase thoughtful designs, but the NZXT C850 Gold Core leans towards a more premium build quality, emphasised by its higher certification ratings. The GIGABYTE P550SS features a flat cable design that enhances cable management and airflow within a PC case, making it a practical choice for those seeking a neat installation. However, the NZXT's emphasis on efficiency and quiet operation suggests a focus on durability and performance under load, which may appeal to users with demanding system requirements.

Safety Features

Safety is a critical consideration when purchasing a power supply, and both models include essential protection features. The NZXT C850 Gold Core is designed with numerous protections to ensure stable operation, minimising the risk of component damage. Similarly, the GIGABYTE P550SS incorporates multiple safeguards, including OVP (Over Voltage Protection), OPP (Over Power Protection), and SCP (Short Circuit Protection), among others. While both power supplies offer robust safety features, the NZXT’s higher efficiency and performance may provide users with added peace of mind during intense computing sessions.

Customer Support and Warranty

A strong warranty and customer support can enhance the overall value of a power supply. The NZXT C850 Gold Core is backed by a reputable brand known for its customer service and often includes a longer warranty period, which can be crucial for users investing in higher-end components. The GIGABYTE P550SS, while offering reliable service, may not match the level of support and warranty period typically associated with premium power supplies like the NZXT. This difference may influence buyers who consider long-term reliability and support to be significant factors in their decision-making process.

Which should you buy?

Choosing between the NZXT C850 Gold Core and the GIGABYTE P550SS ultimately depends on your specific needs and budget. If you prioritise efficiency, noise levels, and future-proofing for high-performance builds, the NZXT C850 Gold Core is the superior option, albeit at a higher price of £89.99. Conversely, if you are looking for a more budget-friendly power supply that still offers decent performance for standard builds, the GIGABYTE P550SS at £40.99 is a solid choice. Ultimately, your decision should align with the level of performance and features you require for your system.
