CORSAIR HX1500i vs Gigabyte P750BS 80 Plus Bronze Non Modular 750w Power Supply Unit

Overview of the Products

The CORSAIR HX1500i and the Gigabyte P750BS are both power supplies designed for different user needs and budget considerations. The CORSAIR HX1500i is priced significantly higher at £229.00 compared to the Gigabyte P750BS, which is available for only £57.55. This stark price difference reflects the features and performance capabilities of each unit, catering to distinct types of users.

The CORSAIR HX1500i is marketed as a high-end power supply, featuring fully modular cabling and compliance with the Intel ATX 3.1 standard, making it suitable for advanced gaming rigs or workstation setups. In contrast, the Gigabyte P750BS offers a more budget-friendly option, still packed with essential features for basic to mid-range systems.

Power Output and Efficiency

Power output is a critical factor when choosing a power supply, and here the CORSAIR HX1500i stands out with a robust capacity of 1500 watts. This makes it ideal for high-performance builds that require significant power for multiple components. The Gigabyte P750BS, on the other hand, provides a maximum output of 750 watts, which is sufficient for many standard gaming and office setups.

In terms of efficiency, the Gigabyte P750BS holds an 80 PLUS Bronze certification, indicating a minimum efficiency of 82% at 20% and 100% loads, and 85% at 50% load. While the CORSAIR HX1500i’s efficiency is not explicitly stated, its high-end design generally suggests a competitive efficiency rating, often exceeding the 80 PLUS standards.

Modularity and Cable Management

When it comes to modularity, the CORSAIR HX1500i excels with its fully modular design, allowing users to connect only the cables needed for their specific build. This feature not only aids in clean and tidy installations but also enhances airflow within the case, which is crucial for maintaining optimal temperatures.

Conversely, the Gigabyte P750BS is a non-modular power supply, meaning all cables are permanently attached. While this may simplify installation for less experienced builders, it can lead to clutter and reduced airflow in setups where not all cables are necessary. Users with limited space in their cases may find this aspect less appealing compared to the CORSAIR's flexibility.

Cooling Solutions

Effective cooling is vital for power supply longevity and performance. The CORSAIR HX1500i boasts a 140mm Fluid Dynamic Bearing fan, which is designed for quiet operation and durability. This feature ensures that the fan operates efficiently, providing cooling without excessive noise, particularly beneficial during demanding tasks.

In comparison, the Gigabyte P750BS includes a 120mm Silent Fluid Dynamic Bearing fan. While it also aims for silent operation, the smaller fan may not provide the same level of cooling efficiency as the larger fan found in the CORSAIR unit. This difference could become apparent during high load scenarios where thermal management is crucial.

Software and Customisation

The CORSAIR HX1500i offers the advantage of powerful CORSAIR iCUE software integration. This allows users to create custom fan curves, monitor power settings in real-time, and switch between single and multi-rail overcurrent protection on-the-fly. Such features provide an enhanced level of control and customisation, appealing to enthusiasts and gamers looking to optimise their systems.

On the other hand, the Gigabyte P750BS does not come with similar software capabilities. Its design focuses more on delivering stable performance without the added features for customisation. For users who do not require extensive control over their power supply settings, this may not be a significant drawback, but it does limit the flexibility that the CORSAIR offers.

Safety Features

Safety is paramount when it comes to power supplies, and both the CORSAIR HX1500i and the Gigabyte P750BS include essential protections. The CORSAIR model features a range of protections, including overcurrent protection, which is critical for safeguarding high-end components during operation.

The Gigabyte P750BS also boasts multiple safety features, including 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 protections provide users with peace of mind, ensuring stable and safe operation of their systems, even under heavy load.

Price-to-Performance Ratio

When evaluating the price-to-performance ratio, the CORSAIR HX1500i is undoubtedly a premium product with a price tag of £229.00. This investment is justified for users needing high wattage, extensive features, and superior build quality. However, for users with less demanding requirements, the cost may be prohibitive.

In contrast, the Gigabyte P750BS presents an extremely attractive option at £57.55, delivering solid performance and essential features suitable for many users. For budget-conscious consumers or those with mid-range systems, the Gigabyte offers excellent value, making it a compelling choice for those who do not require the high-end capabilities of the CORSAIR.

Which should you buy?

Ultimately, the choice between the CORSAIR HX1500i and the Gigabyte P750BS depends on your specific needs and budget. If you are building a high-performance system that requires significant power and advanced features, the CORSAIR HX1500i is the clear winner, justifying its higher price with its extensive capabilities and modular design. Conversely, if you are looking for a reliable, cost-effective solution for a standard build, the Gigabyte P750BS provides excellent value and essential performance at a fraction of the cost.
