JUSTOP Black 750W PSU vs JUSTOP Black 700W Power Supply Unit ATX PSU With 120MM Quiet Fan

Overview of the JUSTOP Black 750W PSU and JUSTOP Black 700W Power Supply

The JUSTOP Black 750W PSU is priced at £32.95, while the JUSTOP Black 700W Power Supply Unit comes in at a slightly lower price of £29.95. The key differences in their specifications and features cater to distinct user needs and preferences, particularly around power output and efficiency.

The 750W PSU offers more power, which could be crucial for users with high-performance components. Meanwhile, the 700W model is designed for those who require a reliable power supply without needing the maximum wattage, making it potentially more cost-effective for standard builds.

Power Output Comparison

The most significant difference between the two products is their power output, with the JUSTOP Black 750W PSU providing 750 watts compared to the 700 watts offered by the JUSTOP Black 700W Power Supply Unit. This 50W difference may seem marginal, but it can impact performance, especially in high-demand scenarios, such as gaming or running resource-intensive applications.

For users planning to build systems with powerful graphics cards or multiple drives, the additional wattage of the 750W PSU may provide the necessary headroom to ensure stable operation. On the other hand, the 700W unit is still sufficiently powerful for mid-range systems and can support a variety of components without issues, making it suitable for users with less demanding needs.

Cooling Systems

Both power supplies are equipped with a cooling fan, but they differ in size and potentially in noise levels. The JUSTOP Black 750W PSU features a 120mm cooling fan, while the JUSTOP Black 700W Power Supply Unit includes a slightly quieter 12CM (120mm) fan.

The 120mm fan in both units is designed to offer efficient airflow, crucial for keeping the internal components cool during operation. However, the focus on a quieter operation in the 700W model might appeal to users who prioritise a silent computing experience, particularly in home or office environments.

Safety Features

Safety is a crucial aspect of power supplies, and both models come with a range of protective features. The JUSTOP Black 750W PSU includes over voltage protection, over power protection, short circuit protection, and thermal overload cut-off protection, ensuring a comprehensive safety net for users.

Similarly, the JUSTOP Black 700W Power Supply Unit also boasts a robust set of safety features, including over voltage protection, under voltage protection, over load protection, and short circuit protection. This alignment in safety features indicates that both units are designed with user safety in mind, providing peace of mind during operation.

Certification and Efficiency

Both power supplies are certified by various safety agencies, including CE, FCC, UL, and TUV, assuring users of their compliance with safety standards. However, the efficiency ratings differ slightly; the JUSTOP Black 700W Power Supply Unit claims a 70% efficiency, while the efficiency of the 750W PSU is not explicitly stated but is implied to be similar.

This efficiency rating is essential for users looking to manage power consumption and reduce electricity costs over time. While both units are efficient enough for standard use, the clear mention of efficiency in the 700W unit makes it a more transparent option for eco-conscious buyers.

Connector Options

Connector availability is another critical factor when choosing a power supply, and both models provide a range of options. The JUSTOP Black 750W PSU includes 1x 24-Pin (20+4), 1x 8-Pin 12V (4+4), 6x SATA, 1x 4-Pin Molex, and 1x 8-Pin PCI-E (6+2). This variety allows for extensive compatibility with various components, making it suitable for diverse builds.

Conversely, the JUSTOP Black 700W Power Supply Unit also offers an adequate selection of connectors, featuring a 24 pin (535mm), 8 pin 12V (545mm), 1 x PCI-E 8-Pin (445mm), 6 x SATA (970mm), and additional Molex connectors. The availability of connectors in both models ensures that users can build their systems according to their specific requirements without compatibility concerns.

Price Considerations

The price difference between the two power supplies stands at £3, with the JUSTOP Black 750W PSU priced at £32.95 and the JUSTOP Black 700W Power Supply Unit at £29.95. This modest price gap could be a deciding factor for budget-conscious consumers who may prefer the 700W model for its lower cost.

While the additional wattage of the 750W PSU may justify its higher price for some users, those with less demanding systems may find the 700W option more aligned with their budget and performance needs. Therefore, the choice between the two could hinge on the specific power requirements of the user's system.

Which should you buy?

When deciding between the JUSTOP Black 750W PSU and the JUSTOP Black 700W Power Supply Unit, consider your system's power requirements, budget, and preferences for noise and efficiency. The 750W model is ideal for high-performance builds needing extra wattage, while the 700W unit offers a more economical solution for standard systems without sacrificing essential safety features and connectivity. Ultimately, your choice should reflect the specific needs of your build and how much you value additional power versus cost savings.
