MSI MAG A750GLS PCIE5, Fully Modular Compact vs Rosewill VMG 850W 80+ Gold, ATX 3.0 & 3.1

Pricing and Value

The MSI MAG A750GLS is priced at $89.99, while the Rosewill VMG 850W comes in at $74.97, making the Rosewill about 17% cheaper. This price difference may appeal to budget-conscious consumers looking for a reliable power supply without sacrificing quality. However, the MSI offers a compact size and modern features like native PCIe 5.1 support, which could justify its higher price. Ultimately, if you're seeking solid performance at a lower price point, the Rosewill is a compelling option.

Power Output and Efficiency

In terms of power output, the MSI MAG A750GLS delivers 750W, whereas the Rosewill VMG provides a higher 850W. Both units boast an 80 PLUS Gold certification, ensuring efficient energy usage, with the MSI achieving up to 90% efficiency. This efficiency rating is crucial for gamers and professionals who demand stable power for high-performance components. If your setup requires more wattage, the Rosewill’s 850W might better meet your needs, particularly for systems with multiple graphics cards or other power-hungry components.

Modular Design

Both power supplies feature a fully modular design, allowing users to connect only the cables they need, which helps to minimize clutter and improve airflow within the case. The MSI MAG A750GLS is equipped with a native 12V-2x6 connector for PCIe 5.1 GPUs, making it particularly suited for the latest graphics cards. On the other hand, the Rosewill VMG also supports this connector and is compatible with both ATX 3.0 and 3.1 standards. This flexibility may make the Rosewill a better choice for users looking to future-proof their systems.

Cooling and Noise Levels

The MSI MAG A750GLS is designed to operate quietly, featuring a 135 mm Fluid-dynamic bearing fan that maintains low noise levels akin to a peaceful night. Conversely, the Rosewill VMG employs a 120 mm FDB silent fan, which also aims to enhance cooling performance. Both units are engineered for optimized thermal control, yet the MSI emphasizes ultra-low noise operation, making it an ideal choice for users who prioritize a silent PC environment, such as gamers and content creators.

Build Quality and Durability

When it comes to build quality, the MSI MAG A750GLS boasts a robust design with an LLC half-bridge and a DC-to-DC converter to ensure reliable output. It also features comprehensive protection mechanisms, including OCP, OTP, OPP, SCP, OVP, UVP, and SIP. Meanwhile, the Rosewill VMG uses 100% Japanese electrolytic capacitors, known for their longevity and reliability. Both power supplies are built to last, but the MSI’s 10-year warranty compared to the Rosewill’s 5-year warranty may provide added peace of mind for those seeking long-term durability.

Compatibility and Future-Proofing

The MSI MAG A750GLS is specifically designed with PCIe 5.1 support, making it a great choice for users planning to utilize NVIDIA’s upcoming 50 series graphics cards. Its compact size also allows for easy installation in most cases. The Rosewill VMG, while compatible with both ATX 3.0 and 3.1, also offers support for next-gen GPUs through its dedicated PCIe 5.1 cable. Users looking for flexibility in their build will find both options appealing, but if future-proofing is a priority, the MSI might have the edge due to its explicit design for the latest technology.

Warranty and Support

The MSI MAG A750GLS comes with an impressive 10-year warranty, a significant commitment to product reliability. In contrast, the Rosewill VMG offers a 5-year warranty. While both warranties indicate confidence in the respective products, the longer warranty period for the MSI could be a deciding factor for consumers concerned about longevity and potential defects. A longer warranty often reflects a manufacturer’s trust in their product’s durability and performance.

Which should you buy?

Choosing between the MSI MAG A750GLS and the Rosewill VMG ultimately depends on your specific needs and budget. If you prioritize efficiency, compact design, and long-term reliability, the MSI MAG A750GLS is worth the extra investment, especially for users looking to build a high-performance gaming rig with the latest GPU technology. However, if you're on a tighter budget and require more wattage, the Rosewill VMG offers excellent performance and compatibility at a more attractive price point. Both power supplies are solid choices, but your decision should hinge on power needs and brand preference.
