MSI MAG A1000GLS PCIE5 Power Supply Unit vs JUSTOP Black 700W Power Supply Unit ATX PSU With 120MM Quiet Fan

Price Comparison

The MSI MAG A1000GLS PCIE5 Power Supply Unit is priced at £104.99, whereas the JUSTOP Black 700W Power Supply Unit is significantly cheaper at £29.95. This price difference of £75.04 highlights the disparity in features and capabilities between the two units. While the JUSTOP model may appeal to budget-conscious consumers, the MSI power supply offers enhanced performance and efficiency, which could justify its higher cost for those requiring robust power for high-demand systems.

Performance and Efficiency

The MSI MAG A1000GLS boasts an impressive 80 PLUS Gold certification, ensuring up to 90% efficiency. This means that for every £100 spent on electricity, only £10 is wasted, making it a highly efficient choice for users with demanding hardware. In contrast, the JUSTOP model operates at 70% efficiency, which indicates that it may waste more energy, potentially leading to higher electricity costs over time. For users looking to maximise performance and minimise energy waste, the MSI unit clearly stands out.

Power Output

When it comes to power output, the MSI MAG A1000GLS delivers a robust 1000W, which is particularly suitable for high-performance systems that may include top-tier GPUs and CPUs. On the other hand, the JUSTOP Black offers a total output of 700W, which may be sufficient for standard builds but could fall short for more demanding setups. This significant difference in wattage means that the MSI power supply is better suited for users who require more headroom for upgrades or intensive tasks.

Build Quality and Design

The MSI MAG A1000GLS features a durable design that incorporates an LLC half-bridge with a DC-to-DC converter and an active PFC design, ensuring reliable output and various protection mechanisms. Its compact size of 150 mm allows for better space management within PC cases. In contrast, the JUSTOP Black also features a solid build with several protection measures including over voltage protection and thermal overload cut-off, but it lacks the higher-end design elements that the MSI offers. The emphasis on build quality in the MSI unit makes it a more appealing choice for gamers and enthusiasts who value reliability.

Noise Levels

For users concerned about noise levels, the MSI MAG A1000GLS operates with an average sound level comparable to a peaceful night, thanks to its 135 mm Fluid-dynamic bearing fan. This design prioritises quiet operation, making it an excellent choice for users who prefer a low-noise environment. Meanwhile, the JUSTOP Black 700W features a 12 cm cooling fan, which also aims to minimise noise, but it operates at a louder 40 dBA. The quieter operation of the MSI power supply will likely be more appealing to those who want a serene computing experience.

Compatibility

The MSI MAG A1000GLS is equipped with native 12V-2x6 PCIe connectors, allowing it to support the latest PCIe 5.1 GPUs and ensuring compatibility with high-end hardware. This is an essential feature for gamers and content creators who require cutting-edge performance. The JUSTOP Black, while compatible with Intel ATX 12V v.2.3 and EPS 12V v.2.92 standards, may not support the latest graphics cards as effectively, limiting its appeal for future-proofing purposes. Compatibility with high-performance components is a crucial factor for many users, and the MSI unit excels in this regard.

Safety Features

Safety is paramount when selecting a power supply. The MSI MAG A1000GLS includes multiple protection features, such as OCP, OTP, OPP, SCP, OVP, UVP, SIP, and NLO, ensuring a comprehensive safety net for your system. The JUSTOP Black also offers several protections, including over voltage protection, short circuit protection, and thermal overload cut-off, but it lacks the extensive range of safeguards that the MSI provides. For users who prioritise safety and reliability, the MSI unit presents a more secure option.

Which should you buy?

In comparing the MSI MAG A1000GLS with the JUSTOP Black 700W Power Supply Unit, the choice largely depends on your specific needs and budget. The MSI unit, with its higher efficiency, greater power output, superior build quality, and extensive safety features, is well worth the investment for those building high-performance systems or seeking long-term reliability. Conversely, the JUSTOP model serves as a budget-friendly option for users with less demanding requirements, but it does sacrifice performance and efficiency. Ultimately, for those aiming for a future-proof and robust setup, the MSI MAG A1000GLS is the recommended choice.
