NZXT C850 Gold Core - 850W ATX 3.1 Power Supply - 80 PLUS Gold - Cybenetics Plat vs SAMA G850 Power Supply - 850W Fully Modular 80 Plus Gold Certified ATX 3.1 & PCI

Price Comparison

The SAMA G850 is slightly more affordable than the NZXT C850 Gold Core, priced at £84.99 compared to £89.99. This £5 difference may influence budget-conscious consumers looking for an 850W power supply. Both products offer similar performance specifications, but the lower price of the SAMA G850 makes it an attractive option for those seeking a quality power supply without breaking the bank.

Efficiency Ratings

Both power supplies boast 80 PLUS Gold efficiency ratings, but the SAMA G850 claims to achieve an impressive efficiency of up to 91.15% at typical loads. In contrast, while the NZXT C850 Gold Core is also energy-efficient, it does not specify its efficiency percentage, making it harder to directly compare. Given this claim, users may find the SAMA G850 to be a better choice for minimising power waste and reducing heat generation during operation.

Build Quality

The NZXT C850 Gold Core is equipped with Cybenetics Platinum efficiency ratings, suggesting a high standard of build quality and performance. It features a fluid dynamic bearing fan designed for whisper-quiet operation, certified for noise levels of less than 15 dBA. On the other hand, the SAMA G850 also emphasises build quality with its premium Japanese capacitors and a 140mm ECO fan, which promotes quiet cooling and longevity. Both power supplies appear to offer excellent build quality, but the NZXT's noise certification gives it a slight edge in terms of quiet operation.

Cable Modularity

The SAMA G850 utilises a fully modular cable design, allowing users to connect only the cables they need for their specific builds. This feature enhances airflow and cable management, presenting a cleaner aesthetic for high-end gaming or workstation setups. Conversely, while the NZXT C850 Gold Core is also compatible with various GPUs and includes a dual-colour 12V-2x6 connector, it does not explicitly state whether it is fully modular. Therefore, for those prioritising a neat and organised build, the SAMA G850 may be the preferable choice.

Compatibility

Both power supplies are designed to support next-generation GPUs, with the NZXT C850 Gold Core specifically highlighting its compatibility with modern NVIDIA graphics cards. It can connect to GPUs using a 12V-2x6 cable or up to three 8-pin PCIe cables. The SAMA G850, however, is compliant with the latest Intel ATX 3.1 standard and PCIe 5.1, featuring a native 12V-2x6 connector for the NVIDIA GeForce RTX 50 and 40 Series. This makes the SAMA G850 particularly appealing for users aiming for the latest GPU technology.

Cooling Solutions

Cooling solutions are essential for maintaining performance and longevity in power supplies. The NZXT C850 Gold Core features a 135mm fluid dynamic bearing fan with a Zero RPM mode for silent operation during light workloads. This design aims to minimise noise while ensuring effective cooling. The SAMA G850 also includes a 140mm fan with fluid dynamic bearing technology, promising quiet operation and vibration damping. With both power supplies incorporating advanced fan technology, users can expect efficient cooling, although the NZXT’s Zero RPM mode may provide an additional level of silence during light loads.

Safety Features

Both power supplies come with a range of safety protections to ensure reliable operation. The SAMA G850 includes comprehensive protections against over-voltage, over-current, over-temperature, and short circuits, ensuring a safe operational environment. Meanwhile, while the NZXT C850 Gold Core does not detail its safety features, the reputable brand typically maintains high safety standards. However, the explicit mention of safety features in the SAMA G850 may provide added confidence for potential buyers.

Which should you buy?

The decision between the NZXT C850 Gold Core and the SAMA G850 ultimately hinges on individual priorities. If budget is a primary concern, the SAMA G850 stands out with its lower price of £84.99 and claims of superior efficiency. Its fully modular design and comprehensive safety features further enhance its appeal. However, if quiet operation and brand reputation are top priorities, the NZXT C850 Gold Core, with its Cybenetics Platinum certification and whisper-quiet performance, may be worth the extra £5. Both power supplies deliver excellent performance, but your choice should align with your specific needs and preferences.
