Gigabyte P750BS 80 Plus Bronze Non Modular 750w Power Supply Unit vs JUSTOP Black 700W Power Supply Unit ATX PSU With 120MM Quiet Fan

Price Comparison

When it comes to pricing, the JUSTOP Black 700W Power Supply Unit is significantly more affordable at £29.95 compared to the Gigabyte P750BS, which is priced at £57.55. This difference of £27.60 makes the JUSTOP an appealing choice for budget-conscious consumers. Despite its lower price, the JUSTOP still offers a respectable 700W output, which is adequate for most systems. On the other hand, the Gigabyte's higher price is reflective of its 80 PLUS Bronze certification, indicating better efficiency with a focus on performance. This makes the Gigabyte a more premium option, suitable for those who prioritise reliability and energy efficiency.

Power Output

The Gigabyte P750BS offers a power output of 750W, which is higher than the JUSTOP's 700W. This additional 50W can be crucial for high-performance systems requiring more power, especially when running high-end graphics cards or multiple components. The Gigabyte's single +12V rail design is also intended to deliver stable power, potentially making it a more robust choice for demanding setups. The JUSTOP, while slightly lower in wattage, still meets the needs of many users and is designed with a single 8-Pin (4+4) 12V rail for stable output. Hence, while the Gigabyte may have the edge in raw power, the JUSTOP is still sufficient for mid-range builds.

Efficiency Ratings

Efficiency is a critical factor in power supplies, and here the Gigabyte P750BS stands out with its 80 PLUS Bronze certification. This certification signifies that the unit operates at a minimum of 82% efficiency under typical load, which can lead to lower electricity bills over time and less heat generation. In contrast, the JUSTOP Black power supply operates with a 70% efficiency rating. While this is acceptable for basic systems, it may not be as cost-effective in the long run as the Gigabyte. Therefore, the Gigabyte is likely to be the better choice for users who are concerned about energy consumption and operational costs.

Cooling Solutions

Cooling is essential for maintaining performance and longevity in power supplies, and both units feature a 120mm cooling fan. However, the Gigabyte P750BS highlights a "Silent Fluid Dynamic Bearing (FDB)" fan, which is designed to reduce noise while effectively dissipating heat. This can be particularly advantageous for users seeking a quieter computing environment. The JUSTOP's fan is described as "quiet," but it does not specify the same advanced technology, which may suggest it is less optimised for noise reduction. Thus, if silent operation is a priority, the Gigabyte may be the preferable choice.

Build Quality and Design

In terms of build quality, the Gigabyte P750BS is designed for high performance and durability, featuring soft-textured embossed cables that enhance the overall aesthetic while also improving manageability within a case. Conversely, the JUSTOP's design is functional and straightforward, focusing on essential features for system builders. While both power supplies are constructed to meet industry standards, the Gigabyte's emphasis on high-quality components and design might appeal more to enthusiasts looking for a premium product. Therefore, those who value aesthetics and build quality may lean towards the Gigabyte.

Protection Features

Both power supplies come equipped with essential protection features, ensuring safe operation. The Gigabyte P750BS includes multiple protections: Over Voltage Protection (OVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Under Voltage Protection (UVP), and Over Current Protection (OCP). This comprehensive protection suite offers peace of mind for users running high-performance systems. Similarly, the JUSTOP also includes OVP, OPP, SCP, and UVP protections, ensuring that it is safe for general use. However, the extensive suite of protections in the Gigabyte may provide additional assurance for users pushing their systems to the limit.

Connector Options

Connector variety is another important consideration when selecting a power supply. The JUSTOP Black features a diverse range of connectors including a 20+4 pin, 4+4 pin, 1 x 6+2 pin PCI-E, 6 SATA connections, and 3 Molex connectors. This variety makes it compatible with a wide range of components, supporting most standard configurations. The Gigabyte P750BS, though not as detailed in its connector specifications, is designed to cater to high-performance builds, featuring a single +12V rail to maintain stable power delivery. Ultimately, while both power supplies provide adequate connector options, the JUSTOP may appeal more to users needing extensive compatibility for various components.

Which should you buy?

Choosing between the Gigabyte P750BS and the JUSTOP Black 700W Power Supply Unit ultimately depends on your specific needs and budget. If you are looking for a power supply that offers higher efficiency, superior build quality, and a more robust power output, the Gigabyte P750BS at £57.55 is a sound investment. However, if you are on a tighter budget and need a reliable power supply for standard usage, the JUSTOP at £29.95 provides excellent value. Each product has its unique advantages, so your decision should be guided by your performance requirements and financial considerations.
