Corsair HX1000i Fully Modular Ultra-Low Noise ATX vs GIGABYTE UD750GM PG5 V2 ICE - 750W 80 Plus

Price Comparison

When comparing prices, the GIGABYTE UD750GM PG5 V2 ICE is significantly more affordable than the Corsair HX1000i. The GIGABYTE unit is priced at $79.99, while the Corsair model costs $234.99, making the Corsair about 194% more expensive. This price difference may be a crucial factor for budget-conscious consumers looking for high-performance power supplies.

The GIGABYTE power supply offers an appealing entry point into the realm of 80 Plus Platinum certified options without breaking the bank. On the other hand, the higher price of the Corsair reflects its additional features and capabilities, which might cater to users with more demanding power needs.

Power Output

The Corsair HX1000i provides a robust 1000W of power, making it ideal for high-end gaming rigs and professional workstations that require substantial energy. In contrast, the GIGABYTE UD750GM PG5 V2 ICE delivers 750W, which is suitable for mid-range builds and less demanding setups. This 250W difference indicates that the Corsair is better suited for configurations that include multiple graphics cards or power-hungry components.

For users whose systems require higher wattage, the Corsair's output is a significant advantage, particularly for future-proofing against potential upgrades. However, for many users, the GIGABYTE's 750W may be perfectly adequate, especially if they are not running extreme configurations.

Efficiency Ratings

Both power supplies are certified with high efficiency, with the Corsair HX1000i boasting an 80 Plus Platinum rating, while the GIGABYTE UD750GM PG5 V2 ICE holds an 80 Plus Gold certification. The Platinum rating of the Corsair translates to higher efficiency in energy usage, typically around 90% or more under load, compared to about 87% for Gold certified units like the GIGABYTE.

This efficiency difference can lead to reduced electricity bills over time, making the Corsair a potentially more economical choice for long-term use despite its higher upfront cost. Therefore, for users prioritizing energy savings, the Corsair might offer better value in the long run.

Modular Design

Both the Corsair HX1000i and GIGABYTE UD750GM PG5 V2 ICE feature fully modular designs, allowing users to connect only the cables they need. This design enhances cable management, leading to cleaner builds and improved airflow. However, the Corsair model stands out for its additional features such as compatibility with CORSAIR iCUE software, enabling users to customize fan curves and monitor power settings.

The GIGABYTE also offers a modular setup but lacks advanced software integration. For users who value customization and monitoring capabilities, the Corsair's modular design may offer a more comprehensive experience.

Cooling Solutions

The cooling systems of both power supplies are designed to ensure efficient operation. The Corsair HX1000i utilizes a 140mm Fluid Dynamic Bearing fan, known for its quiet operation and longevity, even under heavy loads. In contrast, the GIGABYTE UD750GM PG5 V2 ICE is equipped with a 120mm smart hydraulic bearing fan.

While both fans aim to minimize noise, the larger fan in the Corsair may provide better airflow and cooling efficiency, especially during demanding tasks. The quiet operation of the Corsair at low to medium loads, combined with its Zero RPM fan mode, can be particularly appealing for users who prioritize a silent computing environment.

Capacitors and Build Quality

The Corsair HX1000i utilizes high-quality Japanese 105°C-rated electrolytic capacitors, which contribute to its reliability and longevity. This attention to component quality often translates into a longer lifespan for the power supply. The GIGABYTE UD750GM PG5 V2 ICE also employs 100% Japanese capacitors, ensuring a solid performance and endurance.

While both power supplies offer reputable build quality, the emphasis on premium components in the Corsair may provide additional peace of mind for users seeking long-term reliability, especially in high-performance scenarios.

Target Audience

The Corsair HX1000i is tailored for enthusiasts and professionals who require maximum power output, efficiency, and advanced features. It is ideal for users with high-performance systems that demand reliable power delivery. Conversely, the GIGABYTE UD750GM PG5 V2 ICE caters to a more budget-conscious audience, offering solid performance without the need for extreme power levels.

For consumers who might not need the upper-end capabilities of the Corsair, the GIGABYTE provides an attractive option that balances performance and cost-effectiveness, making it suitable for average gamers and everyday users.

Which should you buy?

Ultimately, the decision between the Corsair HX1000i and the GIGABYTE UD750GM PG5 V2 ICE hinges on your specific needs and budget. If you require high wattage, exceptional efficiency, and advanced features, the Corsair is worth the investment despite its higher price tag. However, if you are looking for a reliable power supply that offers excellent performance at a lower cost, the GIGABYTE is a compelling choice. Both power supplies have their merits, so consider your setup and future upgrade plans when making your decision.
