NZXT C850 Gold Core - 850W ATX 3.1 Power Supply - 80 PLUS Gold - Cybenetics Plat vs Gigabyte UD850GM PG5 ICE 80 Plus Gold Fully Modular 850w PCIe 5.0 White Power Su

Overview of the NZXT C850 Gold Core and Gigabyte UD850GM PG5 ICE

When comparing the NZXT C850 Gold Core and the Gigabyte UD850GM PG5 ICE, both power supplies offer robust performance for modern computing needs, yet they cater to slightly different preferences and setups. The NZXT model is priced at £89.99, while the Gigabyte alternative comes in at £99.61. Despite being in the same price bracket, their features and designs reflect distinct approaches to power supply technology.

Efficiency and Performance

Efficiency is a key consideration for power supplies, and both models are certified to 80 PLUS Gold standards, ensuring high energy efficiency. The NZXT C850 Gold Core boasts Cybenetics Platinum efficiency, promising stable performance with reduced heat and power draw even under heavy loads. In contrast, the Gigabyte UD850GM PG5 ICE also ensures reliable energy delivery but highlights its use of 100% Japanese capacitors, which are known for durability and consistent performance. Thus, while both units are efficient, the NZXT may offer slightly superior energy savings in demanding scenarios.

Compatibility with Modern Systems

The NZXT C850 Gold Core is ATX 3.1 certified and features a dual-colour 12V-2x6 connector, making it particularly suitable for next-generation GPUs, including modern NVIDIA graphics cards. On the other hand, the Gigabyte UD850GM PG5 ICE is Intel ATX 3.1 and PCIe Gen 5.1 ready, ensuring compatibility with the latest hardware trends. This makes both power supplies highly adaptable, but the choice may depend on specific GPU requirements, with the NZXT catering more to NVIDIA users.

Design and Modularity

Modularity can significantly affect installation ease and cable management. The Gigabyte UD850GM PG5 ICE features a fully modular design, allowing users to connect only the cables they need, which can help reduce clutter and improve airflow within a case. In comparison, the NZXT C850 Gold Core does not specify a fully modular design but is compatible with multiple GPUs through its flexible cable options. For users prioritising a tidy build with customisable connections, the Gigabyte may have the edge.

Cooling Solutions

Effective cooling is crucial for maintaining performance and longevity in power supplies. The NZXT C850 Gold Core features a 135 mm fluid dynamic bearing fan that operates quietly, with a Zero RPM mode during light workloads, ensuring near-silent operation. Alternatively, the Gigabyte UD850GM PG5 ICE utilises a 120 mm smart hydraulic bearing fan, which is designed for optimised thermal performance. While both fans are designed to minimise noise, the NZXT’s Zero RPM mode may appeal more to users seeking a completely silent operation under low loads.

Protection Features

Protection features are essential for safeguarding components from power supply failures. The Gigabyte UD850GM PG5 ICE comes equipped with a comprehensive suite of protections, including OVP, OPP, SCP, UVP, OCP, and OTP, ensuring that the system is well-protected from various electrical issues. The NZXT C850 Gold Core does not explicitly list its protection features but provides stable performance under demanding loads, which implies reliability. Users prioritising robust protection mechanisms may favour the Gigabyte model.

Pricing and Value

In terms of pricing, the NZXT C850 Gold Core is available for £89.99, making it a slightly more economical choice compared to the Gigabyte UD850GM PG5 ICE, which retails at £99.61. This price difference of £9.62 may be a deciding factor for budget-conscious buyers. Both power supplies offer excellent value for their features, but the lower price point of the NZXT could be enticing for users looking for solid performance without breaking the bank.

User Experience and Noise Levels

User experience is often enhanced by the operational noise levels of hardware components. The NZXT C850 Gold Core is Cybenetics noise certified for whisper-quiet performance, with an A++ rating for low dBA levels, making it an attractive option for users who prioritise a quiet computing environment. The Gigabyte UD850GM PG5 ICE does not specify its noise ratings but is designed to offer optimised thermal solutions, implying a focus on quiet operation as well. However, the explicit noise certification of the NZXT may provide peace of mind for those sensitive to sound.

Which should you buy?

Choosing between the NZXT C850 Gold Core and the Gigabyte UD850GM PG5 ICE ultimately depends on your specific needs and preferences. If you prioritise a slightly lower price, near-silent operation, and compatibility with next-gen NVIDIA GPUs, the NZXT C850 Gold Core is the better option. However, if you prefer a fully modular design, extensive protection features, and are aiming for a system that is Intel ATX 3.1 and PCIe Gen 5.1 ready, you may find the Gigabyte UD850GM PG5 ICE more suitable for your build. Each power supply has its strengths, so consider your hardware requirements and desired features before making a decision.
