Corsair HX1000i Fully Modular Ultra-Low Noise ATX Power Supply - ATX 3.1 & PCIe vs Cooler Master MWE 750 Gold V2 Fully Modular PSU

Overview of Corsair HX1000i and Cooler Master MWE 750 Gold V2

The Corsair HX1000i is priced at £169.99, while the Cooler Master MWE 750 Gold V2 is more affordable at £141.41. Both power supplies are fully modular, allowing for streamlined cable management and efficient airflow in your PC build. However, they target different power needs and efficiency standards, which may influence your decision based on your specific system requirements.

The Corsair HX1000i, with its 1000W output, is designed for high-performance gaming rigs and workstations that demand substantial power. In contrast, the Cooler Master MWE 750 Gold V2, with a 750W output, is suitable for mid-range builds or systems with lower power requirements. This fundamental difference in wattage can significantly affect your system's performance and power efficiency.

Efficiency Ratings and Performance

The Corsair HX1000i boasts compliance with the latest ATX 3.1 power standard, which supports PCIe Gen 5.1 platforms. Its advanced design helps it resist transient power spikes effectively. This is particularly beneficial for users with high-performance graphics cards, as it can handle increased power demands without compromising stability.

On the other hand, the Cooler Master MWE 750 Gold V2 holds an 80 PLUS Gold certification, indicating a minimum efficiency of 90% under typical loads. This efficiency rating is crucial for reducing energy costs and heat generation, making it a smart choice for those looking to optimise their power usage while gaming. The MWE 750's efficiency can also result in a longer lifespan for your components due to reduced heat stress.

Cooling Solutions

The Corsair HX1000i features a 140mm Fluid Dynamic Bearing (FDB) fan, which is designed for ultra-low noise operation and longevity. This fan remains quiet even under load, thanks to the Zero RPM Fan Mode, which allows it to switch off entirely at lower loads. This feature ensures that the power supply operates silently during less demanding tasks, providing a more pleasant user experience.

Conversely, the Cooler Master MWE 750 Gold V2 utilises a 120mm hydro-dynamic bearing (HDB) fan that employs temperature-responsive fan-speed control. This means that the fan operates quietly during low-demand periods but ramps up when the system requires more power. Although it may not have a complete Zero RPM mode, the fan’s responsive nature helps maintain system cooling without excessive noise, making it suitable for a range of applications.

Cable Management and Build Quality

Cable management is crucial for both aesthetics and airflow within a PC case. The Corsair HX1000i offers fully modular cabling, allowing users to connect only the cables necessary for their system. This feature not only simplifies the build process but also helps maintain a clean interior and improves airflow by reducing clutter.

The Cooler Master MWE 750 Gold V2 also features fully modular flat black cabling, which enhances the overall look of your build. This design contributes to better ventilation by eliminating unnecessary cables that can obstruct airflow. Both power supplies excel in cable management, but the choice between them may come down to personal style preferences and system requirements.

Temperature Resilience

When it comes to temperature resilience, the Corsair HX1000i operates efficiently under varying conditions, although specific temperature thresholds are not detailed. Its design aims to handle high-performance demands, making it suitable for overclocking and intense gaming sessions.

In comparison, the Cooler Master MWE 750 Gold V2 is rated for a higher temperature threshold of 50°C, compared to its predecessor’s 45°C. This increased resilience makes it an excellent choice for users who intend to push their systems to the limit, such as during overclocking or intensive rendering tasks. The ability to handle higher temperatures can prolong the lifespan of the power supply and connected components.

Software and Monitoring Features

The Corsair HX1000i comes equipped with powerful CORSAIR iCUE software, which allows users to create custom fan curves, monitor power settings, and toggle between single to multi-rail overcurrent protection (OCP) on the fly. This level of control can significantly enhance user experience, particularly for those who enjoy customising and optimising their system performance.

In contrast, the Cooler Master MWE 750 Gold V2 does not feature dedicated software for monitoring or customisation. While it offers reliable performance and user-friendly installation, the lack of software control may be a drawback for enthusiasts who value real-time monitoring and adjustments. This difference could influence decisions for users who prioritise advanced features in their power supply.

Price Comparison

With a price of £169.99, the Corsair HX1000i is positioned as a premium option, reflecting its advanced features, higher wattage, and robust performance capabilities. It targets users with high demands for power and efficiency, making it a fitting choice for high-end gaming rigs or professional workstations.

On the other hand, the Cooler Master MWE 750 Gold V2 is priced at £141.41, making it more accessible for budget-conscious consumers or those building mid-range systems. While it may offer fewer high-end features compared to the Corsair model, its efficiency and reliable performance still provide excellent value.

Which should you buy?

Deciding between the Corsair HX1000i and the Cooler Master MWE 750 Gold V2 ultimately depends on your specific needs and budget. If you require a high-output power supply with advanced features like iCUE software and superior noise control, the Corsair HX1000i is the clear winner. However, if you are looking for a cost-effective solution that still delivers excellent efficiency and performance for a mid-range build, the Cooler Master MWE 750 Gold V2 will serve you well. Consider your system’s power demands, cooling needs, and whether you value additional software features when making your choice.
