Corsair HX1000i Fully Modular Ultra-Low Noise ATX Power Supply - ATX 3.1 & PCIe vs SAMA G850 Power Supply - 850W Fully Modular 80 Plus Gold Certified ATX 3.1 & PCI

Price Comparison

The Corsair HX1000i is significantly more expensive than the SAMA G850, priced at £169.99 compared to £84.99. This difference of £85 indicates a premium for the features and performance offered by the Corsair model. While the SAMA G850 provides excellent value at a lower price point, the additional investment in the Corsair might be justified for users seeking advanced capabilities and higher efficiency in their power supply.

Efficiency Ratings

When it comes to efficiency, the SAMA G850 boasts an 80 Plus Gold certification, achieving up to 91.15% efficiency at typical loads. This not only reduces energy waste but also lowers heat generation, which is crucial for high-performance systems. In contrast, while the Corsair HX1000i is compliant with the Intel ATX 3.1 standard, specific efficiency ratings are not provided in the product details. However, its advanced features may suggest a competitive performance level, although the absence of a specific certification makes it less clear in direct efficiency comparisons.

Build Quality and Design

The Corsair HX1000i features fully modular cabling, allowing users to connect only the cables their system requires, promoting a cleaner build. This model also includes a 140mm Fluid Dynamic Bearing fan designed for quiet performance. On the other hand, the SAMA G850 also offers a fully modular cable design, enhancing airflow and aesthetics. It is equipped with premium Japanese capacitors and a silent 140mm ECO fan. Both power supplies prioritise build quality, but the Corsair may have the edge in fan technology and overall longevity due to its brand reputation.

Noise Levels

Noise levels are a critical factor for many users, especially those building gaming or workstation PCs. The Corsair HX1000i operates with a Zero RPM Fan Mode, which allows the fan to switch off entirely at low and medium loads, ensuring near-silent operation. This feature is particularly appealing for users who value a quiet computing environment. Conversely, the SAMA G850 includes a silent 140mm FDB fan, designed for quiet cooling and vibration damping. While both power supplies aim to minimise noise, the Corsair’s Zero RPM feature provides a distinct advantage in low-load scenarios.

Compatibility

In terms of compatibility, both power supplies are designed to meet the latest standards. The Corsair HX1000i is Intel ATX 3.1 certified and supports the PCIe Gen 5.1 platform, making it suitable for the latest graphics cards and components. The SAMA G850 also complies with the Intel ATX 3.1 standard and features a native 12V-2x6 connector for NVIDIA GeForce RTX 50 and 40 Series GPUs. This makes both units highly compatible with modern hardware; however, Corsair’s support for the latest PCIe standard may provide a slight edge for future-proofing.

Cooling Performance

Cooling performance is essential for maintaining system stability, especially under heavy loads. The Corsair HX1000i's 140mm Fluid Dynamic Bearing fan is noted for its quiet operation and long life, suggesting effective cooling capabilities. The SAMA G850 also includes a 140mm ECO fan with Fluid Dynamic Bearing technology, ensuring efficient cooling and vibration damping. Both models leverage advanced fan technology, but the performance in real-world scenarios may vary based on system load and configuration.

User Control Features

The Corsair HX1000i stands out with its powerful CORSAIR iCUE software, which allows users to create custom fan curves, monitor power settings, and toggle between single to multi-rail overcurrent protection on the fly. This level of control is beneficial for enthusiasts who want to fine-tune their power supply performance. The SAMA G850 does not mention any software control features, which may limit its appeal for users looking for advanced monitoring and configuration options.

Which should you buy?

Choosing between the Corsair HX1000i and the SAMA G850 ultimately depends on your specific needs and budget. If you require a high-efficiency power supply with advanced features, extensive control options, and a focus on quiet operation, the Corsair HX1000i is worth the investment at £169.99. However, for users seeking a reliable and efficient power supply at a more accessible price, the SAMA G850 at £84.99 offers great value without compromising essential performance features.
