MSI MAG A750GL PCIE5 Power Supply Unit vs Fasgear PCI-e 5.0 12VHPWR

Overview of the Products

In this comparison, we will examine the MSI MAG A750GL PCIE5 Power Supply Unit and the Fasgear PCI-e 5.0 12VHPWR cable. The MSI power supply is priced at £74.99 and offers a robust set of features, while the Fasgear extension cable is significantly cheaper at £18.00. Each product serves a different purpose: one is a complete power supply unit, and the other is an extension cable designed for use with specific graphics cards.

Power and Performance

The MSI MAG A750GL delivers a powerful 750W output, making it suitable for high-end gaming systems, especially those requiring substantial power for GPUs and CPUs. This unit is 80 PLUS Gold certified, achieving up to 90% efficiency, which means reduced energy consumption and heat generation. In contrast, the Fasgear extension cable supports an output of up to 600W, making it ideal for extending power to GPU setups that demand high wattage. However, it requires a suitable power supply with unoccupied 8-pin PCI-e ports to function correctly.

Design and Build Quality

The MSI MAG A750GL boasts a compact design with a length of just 140mm, making it easy to fit into most cases while allowing for improved airflow and cable management. It also features a full modular design, which helps maintain a tidy build. Meanwhile, the Fasgear cable is designed for flexibility with a length of 30cm, providing a neat and tidy solution for extending GPU power connections. The use of 16AWG tinned copper wire in the Fasgear cable enhances its durability compared to standard cables, which is an important factor to consider when managing heat and power delivery.

Compatibility

The MSI MAG A750GL is compatible with the latest PCIe 5.0 GPUs, providing 450W of power over its native 16-pin PCIe connector. It supports both NVIDIA and AMD graphics cards, making it a versatile choice for gamers and PC builders alike. On the other hand, the Fasgear extension cable is specifically designed for use with RTX 3090ti, 4070, 4080, and 4090 models, among others. This narrow compatibility means it is essential for users to ensure their GPU matches the cable’s specifications to avoid performance issues.

Cooling Solutions

Cooling is a critical aspect of power supplies and extensions alike. The MSI MAG A750GL features a 120mm fluid dynamic bearing fan, which is designed for reliable cooling performance, essential for maintaining system stability under load. The compact design aids in airflow, ensuring that the PSU operates efficiently. The Fasgear cable, while not having an active cooling mechanism, does not generate heat on its own; however, it relies on the cooling capabilities of the power supply and GPU it connects to.

Warranty and Support

The MSI MAG A750GL comes with a generous 7-year limited warranty, reflecting the brand's confidence in its product's longevity and reliability. This warranty is a significant advantage for users investing in a high-performance power supply. In contrast, the Fasgear cable does not explicitly mention a warranty, which could be a consideration for potential buyers. The lack of a warranty may lead to concerns regarding long-term reliability, especially when dealing with high-powered components.

Price Considerations

At £74.99, the MSI MAG A750GL is positioned as a premium power supply with a robust feature set, aimed at gamers and PC enthusiasts who require efficient and reliable power. The Fasgear extension cable, at £18.00, is a budget-friendly option for those looking to extend their GPU's power supply without the need for a complete PSU replacement. The price difference is substantial, and buyers will need to evaluate their needs carefully—whether they require a full power supply or simply an extension cable.

Which should you buy?

Choosing between the MSI MAG A750GL PCIE5 Power Supply Unit and the Fasgear PCI-e 5.0 12VHPWR extension cable comes down to your specific needs and setup. If you are building a high-performance gaming rig that requires a reliable and efficient power supply, the MSI MAG A750GL is the clear choice with its 750W output, 80 PLUS Gold certification, and extensive compatibility with high-end GPUs. However, if you already have a suitable power supply and need a reliable extension for your GPU connection, the Fasgear cable offers a cost-effective solution at just £18. Ultimately, consider your current setup and future needs to make the most informed decision.
