Cooler Master MWE 750 Gold V2 Fully Modular PSU vs JUSTOP Black 700W Power Supply Unit ATX PSU With 120MM Quiet Fan

Price Comparison

The Cooler Master MWE 750 Gold V2 is significantly more expensive than the JUSTOP Black 700W Power Supply Unit. Priced at £141.41, the Cooler Master offers high-end features suitable for demanding systems, while the JUSTOP, at just £29.95, is aimed at budget-conscious users. This considerable price difference of £111.46 indicates that the Cooler Master is designed for users seeking premium performance, whereas the JUSTOP is an entry-level option that may suffice for less intensive applications.

Efficiency Ratings

Efficiency is a critical factor for power supplies, and here the Cooler Master MWE 750 Gold V2 excels with an 80 PLUS Gold rating, achieving a remarkable 90% efficiency under typical loading conditions. This efficiency not only reduces energy costs but also minimises heat production, a vital consideration for high-performance gaming systems. Conversely, the JUSTOP Black 700W is rated at 70% efficiency. This lower rating means it may consume more power and generate more heat during operation, which could impact the overall performance and longevity of connected components.

Build Quality and Design

The Cooler Master MWE 750 Gold V2 features fully modular flat black cabling, allowing for superior cable management. This design enhances the aesthetic appeal of a PC build and improves airflow by eliminating unnecessary cables. In contrast, the JUSTOP Black 700W uses standard cabling without the fully modular benefit, which might lead to a cluttered interior and potential airflow issues. Thus, the Cooler Master caters to those prioritising build aesthetics and airflow efficiency, whereas the JUSTOP may appeal more to users who are less concerned about these elements.

Cooling Performance

Cooling performance is another area where the Cooler Master MWE 750 Gold V2 stands out. It is equipped with a responsive 120mm hydro-dynamic bearing fan that adjusts its speed based on temperature, ensuring quiet operation during low-demand periods. The JUSTOP Black 700W includes a 12cm cooling fan which also aims for quiet operation, but it does not specifically mention temperature-responsive features. As such, while both power supplies focus on quiet operation, the Cooler Master provides a more sophisticated cooling solution that actively adapts to system needs.

Compatibility and Connectors

The Cooler Master MWE 750 Gold V2 offers extensive compatibility with multiple connectors, including 2 EPS connectors and support for ATX 24 Pin, EPS 4+4 Pin, and various PCI-e connections. This makes it a versatile option for a wide range of motherboards and graphics cards. The JUSTOP Black 700W, while compatible with Intel ATX 12V and EPS standards, provides a more limited selection of connectors. It comes with a single 8-Pin 12V rail and fewer total connectors, making the Cooler Master a better choice for users with advanced setups requiring multiple connections.

Safety Features

Safety is paramount in power supplies, and both units come with protective features. The Cooler Master MWE 750 Gold V2 is designed to handle higher temperatures, with a resilience threshold of 50°C, making it suitable for overclocking scenarios. It also incorporates multiple safety protections, though specific details are not provided. The JUSTOP Black 700W includes over voltage protection, over power protection, short circuit protection, and thermal overload cut-off protection, ensuring a safe operation. While both power supplies offer essential safety features, the Cooler Master’s higher temperature tolerance gives it an edge for high-performance environments.

Target Audience

The target audience for these two power supplies differs greatly. The Cooler Master MWE 750 Gold V2 is designed for gaming enthusiasts and professionals who require high efficiency, performance, and reliability for demanding applications. Its premium features justify its higher price point. Conversely, the JUSTOP Black 700W is aimed at casual users or those building budget systems, offering basic functionality at a fraction of the cost. This clear division means that buyers should consider their specific needs and budget constraints when choosing between these two options.

Which should you buy?

Ultimately, the choice between the Cooler Master MWE 750 Gold V2 and the JUSTOP Black 700W depends on your specific needs and budget. If you require a high-efficiency, high-performance power supply with advanced features for gaming or professional use, the Cooler Master is the clear winner at £141.41. However, if you are building a basic system and need a cost-effective option without the bells and whistles, the JUSTOP at £29.95 is a sensible choice. Assessing your priorities will determine which power supply best suits your requirements.
