Gigabyte P750BS 80 Plus Bronze Non Modular 750w Power Supply Unit vs Corsair HX1000i Fully Modular Ultra-Low Noise ATX Power Supply - ATX 3.1 & PCIe

Price Comparison

When it comes to price, the Gigabyte P750BS is significantly more affordable at £57.55 compared to the Corsair HX1000i, which retails at £169.99. This is a difference of £112.44, making the Gigabyte model a more budget-friendly choice for users seeking a reliable power supply without breaking the bank. The substantial price gap reflects the differing features and capabilities of both power supplies, with the Corsair model offering advanced features that justify its higher price point.

Power Output and Efficiency

The Gigabyte P750BS provides a robust 750 watts of power, making it suitable for a wide range of mid to high-performance systems. It boasts an 80 PLUS Bronze certification, ensuring efficient power delivery and reduced energy consumption compared to standard power supplies. In contrast, the Corsair HX1000i, with its higher output of 1000 watts, is designed for more demanding setups, especially those requiring multiple high-end GPUs. The added power capacity and efficiency standards of the HX1000i cater to enthusiasts looking for top-tier performance.

Modularity

Modularity is a key difference between these two power supplies. The Gigabyte P750BS features a non-modular design, which means all cables are permanently attached. While this can simplify installation for some users, it may create clutter in cases with excess cables not in use. On the other hand, the Corsair HX1000i is fully modular, allowing users to connect only the cables they need. This flexibility not only promotes cleaner builds but also enhances airflow within the case, which is particularly beneficial for high-performance systems.

Cooling Solutions

Cooling performance is another critical aspect where these two models differ. The Gigabyte P750BS is equipped with a 120mm Silent Fluid Dynamic Bearing (FDB) fan, which aims to provide quiet operation during use. However, the Corsair HX1000i takes cooling a step further with a larger 140mm Fluid Dynamic Bearing fan designed for ultra-low noise levels. Additionally, the HX1000i features a Zero RPM Fan Mode that turns off the fan entirely at low to medium loads, achieving near-silent operation. This advanced cooling system makes the Corsair model more appealing to users prioritising quiet performance.

Protection Features

Both power supplies incorporate essential protection features, but they vary in complexity. The Gigabyte P750BS includes multiple protection mechanisms such as Over Voltage Protection (OVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Under Voltage Protection (UVP), Over Current Protection (OCP), and Over Temperature Protection (OTP). These features ensure safe operation and longevity. Conversely, the Corsair HX1000i not only includes similar protections but also benefits from the powerful CORSAIR iCUE software, which allows users to monitor power settings and toggle between different overcurrent protection modes. This level of control is particularly useful for enthusiasts who want to optimise their system's performance.

Compatibility and Standards

In terms of compatibility, the Corsair HX1000i is Intel ATX 3.1 certified, meaning it adheres to the latest power standards and supports the PCIe Gen 5.1 platform. This compliance allows it to handle transient power spikes effectively, making it an excellent choice for cutting-edge builds. The Gigabyte P750BS, while versatile, does not mention specific compatibility with these newer standards. Users planning to build or upgrade a system with the latest components may find the Corsair model more future-proof due to its adherence to the latest specifications.

User Experience and Software

The user experience is enhanced significantly with the Corsair HX1000i due to its integration with CORSAIR’s iCUE software. This software allows users to create custom fan curves, monitor power usage, and adjust overcurrent protection settings on-the-fly. This level of interactivity can be particularly appealing to gamers and PC enthusiasts who want to fine-tune their systems for optimal performance. In contrast, the Gigabyte P750BS, while reliable, does not offer similar software capabilities, which may limit its appeal to users seeking an interactive experience.

Which should you buy?

Ultimately, the choice between the Gigabyte P750BS and the Corsair HX1000i depends on your specific needs and budget. If you're looking for an affordable, efficient power supply for a mid-range build, the Gigabyte model offers solid performance at a fraction of the cost. However, if you're aiming for a high-performance system with advanced features, modularity, and enhanced cooling solutions, the Corsair HX1000i justifies its higher price with superior capabilities and future-proofing attributes. Consider what aspects are most important for your setup before making your decision.
