Gigabyte UD850GM PG5 ICE 80 Plus Gold Fully Modular 850w PCIe 5.0 White Power Su vs Corsair HX1000i Fully Modular Ultra-Low Noise ATX Power Supply - ATX 3.1 & PCIe

Pricing Comparison

The Gigabyte UD850GM PG5 ICE is priced at £99.61, while the Corsair HX1000i comes in significantly higher at £169.99. This notable difference of £70.38 may influence buyers who are budget-conscious or looking for the best value. The Gigabyte model presents a compelling option for those seeking a high-performance power supply without breaking the bank, while Corsair's offering targets users willing to invest more for additional features and performance.

Design and Build Quality

Both the Gigabyte UD850GM PG5 ICE and Corsair HX1000i are fully modular power supplies, allowing users to connect only the cables needed for a clean build. The Gigabyte unit boasts a compact size, which can be advantageous for smaller cases. In contrast, the Corsair model features a larger 140mm Fluid Dynamic Bearing fan, designed for quieter operation and longevity. The choice of using 100% Japanese capacitors in the Gigabyte model suggests high-quality components aimed at durability, while Corsair's design prioritises noise reduction and fan control through its iCUE software.

Efficiency Ratings

The Gigabyte UD850GM PG5 ICE is certified with an 80 PLUS Gold rating, indicating that it operates at high efficiency, minimising wasted power. This certification ensures that users can expect reliable energy delivery with lower electricity bills over time. The Corsair HX1000i, while also meeting the ATX 3.1 power standard, does not explicitly mention an efficiency rating in the provided data. However, its compliance with ATX standards suggests a focus on performance stability and handling transient power spikes effectively, which may appeal to users with high power demands.

Cooling Solutions

Cooling is a critical aspect of power supply performance, and both models employ different cooling technologies. The Gigabyte power supply features a 120mm smart hydraulic bearing fan, optimised for thermal solutions and efficient cooling. On the other hand, the Corsair HX1000i utilises a larger 140mm fan with a Zero RPM mode, allowing the fan to remain off during low and medium loads for silent operation. This feature can be particularly useful in quiet environments where noise reduction is a priority, making the Corsair model potentially more appealing for users seeking a silent system.

Additional Features

The additional features offered by each power supply can significantly impact user experience. The Gigabyte UD850GM PG5 ICE includes comprehensive protection mechanisms such as OVP, OPP, SCP, UVP, OCP, and OTP, ensuring safety and reliability during operation. Conversely, the Corsair HX1000i comes equipped with the powerful iCUE software, enabling users to create custom fan curves and monitor power settings. This level of control and monitoring can enhance user experience, especially for those who enjoy customising their system performance.

Compatibility and Future-Proofing

In terms of compatibility, both power supplies support Intel ATX 3.1 and PCIe Gen 5.1, making them suitable for current and future high-performance components. The Gigabyte model is specifically designed for reliable power delivery to high-performance systems, which may attract gamers and professionals alike. The Corsair HX1000i also supports the latest standards, providing a level of future-proofing. However, its higher price may reflect additional features that cater to enthusiasts who require more from their power supplies.

Brand Reputation and Support

Both Gigabyte and Corsair are well-regarded brands in the power supply market, known for their quality and reliability. Corsair has built a strong reputation for premium products, often favoured by gamers and PC builders for their performance and design. Gigabyte, while also reputable, offers a more budget-friendly option without sacrificing essential features. The choice between the two brands may ultimately depend on consumer loyalty and the specific needs of the user, such as support options and warranty terms.

Which should you buy?

Choosing between the Gigabyte UD850GM PG5 ICE and the Corsair HX1000i ultimately hinges on budget, performance needs, and feature preferences. The Gigabyte model is an excellent choice for those looking for a high-quality power supply at a competitive price of £99.61, offering significant features like an 80 PLUS Gold rating and robust protection mechanisms. In contrast, the Corsair HX1000i, priced at £169.99, caters to users willing to invest in enhanced features such as iCUE software and a quieter cooling solution. For those prioritising cost-effectiveness, the Gigabyte UD850GM is a clear winner, while the Corsair is better suited for users desiring advanced customisation and low-noise operation.
