Price Comparison

When it comes to pricing, the Rosewill VMG 850W 80+ Gold is priced at $74.97, making it about 1.36% cheaper than the Thermaltake Smart BM3 750W 80Plus Bronze, which retails for $75.99. Though the difference is minimal, the Rosewill model offers a higher wattage, providing more power for slightly less money. This may be a crucial factor for users looking to maximize their investment in a power supply, especially if they plan on using high-performance components.

Power Output

The Rosewill VMG 850W 80+ Gold delivers 850W of power, significantly outpacing the Thermaltake Smart BM3, which offers 750W. This 100W difference is substantial for users who plan to run multiple high-end graphics cards or a power-hungry CPU. The additional wattage ensures that the system can handle higher loads without straining the power supply, making the Rosewill a better choice for gamers and professionals who demand top performance.

Efficiency Ratings

Both power supplies are certified for efficiency, but they differ in rating. The Rosewill VMG boasts an 80+ Gold certification, which means it is more efficient than the Thermaltake Smart BM3's 80Plus Bronze rating. This distinction translates to lower energy costs over time, as the Rosewill will waste less electricity as heat. For users concerned about their energy bills or looking to build a more environmentally friendly system, the Rosewill’s higher efficiency is an important consideration.

Modular Design

The Rosewill VMG features a full modular design, allowing users to connect only the cables they need for their build. This can lead to better airflow and a cleaner look inside the case. In contrast, the Thermaltake Smart BM3 is semi-modular, meaning some cables are fixed and cannot be removed. While both designs offer some flexibility, the full modular approach of the Rosewill is generally more desirable for tech enthusiasts who prioritize cable management.

Cooling and Noise Levels

In terms of cooling performance, both units feature a 120mm fan, but they differ in technology. The Rosewill VMG utilizes a fluid dynamic bearing (FDB) fan designed for low noise levels, while the Thermaltake Smart BM3 also has a fluid dynamic bearing fan but includes a Smart Zero Fan function, which keeps the fan off at low loads to minimize noise. For users who value a quiet working environment, the Smart Zero Fan function may be appealing, yet the silent operation of the Rosewill’s FDB fan is also commendable, particularly under load.

Build Quality and Components

The Rosewill VMG uses 100% Japanese electrolytic capacitors, known for their longevity and reliability. The Thermaltake Smart BM3 also features high-quality Japanese capacitors, rated for 105°C (221°F), which enhances durability. While both power supplies boast quality components, the assurance of 100% Japanese capacitors in the Rosewill model may provide users with added peace of mind regarding reliability and lifespan in demanding applications.

Warranty and Support

Both the Rosewill VMG and the Thermaltake Smart BM3 come with a 5-year warranty, demonstrating a commitment from both brands to quality and customer satisfaction. This warranty period is standard in the industry for power supplies and allows users to invest with confidence, knowing they are protected against defects and failures. While the warranty period is the same, the additional features and performance of the Rosewill may make it a more attractive option for those looking for long-term reliability.

Which should you buy?

In deciding between the Rosewill VMG 850W 80+ Gold and the Thermaltake Smart BM3 750W 80Plus Bronze, the Rosewill emerges as the stronger contender. It offers higher wattage, better efficiency, and a fully modular design, all for a slightly lower price. While the Thermaltake’s Smart Zero Fan function is an appealing feature for reducing noise, the overall performance and build quality of the Rosewill make it the better choice for most users seeking a robust and reliable power supply.
