MSI MAG A750GL PCIE5 Power Supply Unit vs Asus ROG Strix 1200W Platinum PSU

Overview of the MSI MAG A750GL PCIE5 Power Supply Unit and Asus ROG Strix 1200W Platinum PSU

The MSI MAG A750GL PCIE5 Power Supply Unit is priced at £74.99, while the Asus ROG Strix 1200W Platinum PSU costs £179.99. This significant price difference reflects the varying features and capabilities of both power supplies, catering to different user needs. While the MSI model focuses on efficiency and compact design, the Asus variant emphasises high performance and advanced cooling technologies.

Efficiency and Certification

Efficiency is a key differentiator between the two power supplies. The MSI MAG A750GL boasts an 80 PLUS Gold certification, indicating it achieves up to 90% efficiency under typical loads. This certification is ideal for high-end systems, as it reduces energy consumption and heat generation. In contrast, the Asus ROG Strix does not specify its efficiency rating; however, it employs GaN MOSFET technology, which enhances power efficiency by up to 30%. This innovative technology contributes to reduced energy waste, although it does not come with a specific certification like the MSI unit.

Modularity and Cable Management

When considering modularity, the MSI MAG A750GL stands out with its fully modular design. This feature allows users to connect only the cables they need, which significantly improves airflow and reduces clutter within the case. The clean, flat black cables included with the MSI unit contribute to an aesthetically pleasing setup. The Asus ROG Strix, while not detailed on modularity, typically features a semi-modular design, which might not provide the same level of customisation or cable management efficiency as the MSI model.

Power Output and GPU Support

The MSI MAG A750GL offers robust power support with its native 16-pin PCIe connector, capable of delivering up to 450W to PCIe 5.0 GPUs. This capability makes it suitable for modern high-performance graphics cards from both NVIDIA and AMD. On the other hand, the Asus ROG Strix provides a substantial 1200W output, but specific GPU power delivery details are not mentioned. The high wattage suggests that it can support multiple high-end GPUs, making it a suitable choice for users with extensive gaming setups or high-performance requirements.

Cooling Performance

Cooling technology plays a crucial role in the performance and longevity of power supplies. The MSI MAG A750GL is equipped with a 120mm fluid dynamic bearing fan, providing reliable cooling while maintaining a compact design of only 140mm in length. This design helps promote better airflow and cable management. Meanwhile, the Asus ROG Strix incorporates large ROG heatsinks, which cover critical components to ensure lower temperatures and reduced noise levels compared to standard designs. Additionally, the dual ball fan bearings in the Asus model can last up to twice as long as traditional sleeve bearing fans, enhancing its durability.

Noise Levels and Quiet Operation

For users who value quiet operation, the MSI MAG A750GL and Asus ROG Strix both offer features aimed at reducing noise. The MSI unit's fan design is optimised for efficient cooling, which can help maintain a quieter environment. In contrast, the Asus ROG Strix boasts 0dB technology, allowing for silent operation during light gaming sessions. This feature is particularly appealing for gamers who prefer a noise-free experience when not under heavy load.

Build Quality and Durability

Both power supplies are designed with durability in mind, but they employ different technologies to achieve this. The MSI MAG A750GL features a full-bridge LLC design with a DC-to-DC converter and active PFC, ensuring robust output and multiple protections including over current, over voltage, and short-circuit protection. In comparison, the Asus ROG Strix focuses on superior internal layout and cooling, which contributes to a longer lifespan and consistent performance under load. The dual ball fan bearings in the Asus model further enhance its longevity compared to the MSI's standard fan design.

Which should you buy?

Ultimately, the choice between the MSI MAG A750GL PCIE5 Power Supply Unit and the Asus ROG Strix 1200W Platinum PSU hinges on your specific needs and budget. If you are looking for an efficient, cost-effective solution with a focus on cable management and compact design, the MSI MAG A750GL at £74.99 is an excellent choice. However, if your requirements include high wattage for multiple GPUs, advanced cooling technology, and a focus on performance, the Asus ROG Strix at £179.99 may justify its higher price tag. Assess your system's needs and budget to make the best decision for your setup.
