Overview of the Products
In this comparison, we will evaluate the MSI MPG A850GS PCIE5 and the Thermaltake Smart 500W 80+ White Certified PSU. The MSI power supply is priced at $110.99, while the Thermaltake option is considerably cheaper at $39.99, making it about 64% less expensive. Despite the price difference, both products cater to different user needs and system requirements.
Performance and Efficiency
The MSI MPG A850GS boasts an 80 Plus Gold certification, indicating high efficiency, with a design that maximizes performance under load. It offers 850 watts of power, perfect for high-demand gaming systems. In contrast, the Thermaltake Smart 500W has an 80 Plus certification that ensures 80% efficiency under typical load, delivering a continuous output of 500 watts. While the MSI offers nearly double the wattage, the Thermaltake's efficiency is sufficient for mainstream builds, which may not require as much power.
Build Quality and Components
The MSI MPG A850GS utilizes 100% all Japanese 105 C capacitors, ensuring durability and reliability under heavy use. It also features industrial-level protections, including overvoltage and overcurrent protection. On the other hand, the Thermaltake Smart 500W incorporates high-quality components but does not specify the types of capacitors used. Its design includes a single +12V rail that enables stable performance but may not match the robustness of the MSI’s components in demanding scenarios.
Noise Levels and Cooling
One significant aspect of both power supplies is their cooling solutions. The MSI MPG A850GS is designed to operate quietly with low-noise features, contributing to a more comfortable gaming environment. The Thermaltake Smart 500W, equipped with a 120mm ultra-quiet cooling fan, also emphasizes low noise levels. While both power supplies aim to minimize operational sound, the Thermaltake's fan is specifically noted for providing excellent airflow at low noise, making it an attractive choice for budget-conscious users seeking quiet operation.
Warranty and Support
The MSI MPG A850GS comes with a substantial 10-year warranty, reflecting the manufacturer's confidence in its product's longevity and reliability. This warranty could be a deciding factor for users who prioritize long-term investment. Conversely, the Thermaltake Smart 500W offers a 5-year warranty, which, while decent, does not match the extensive coverage provided by MSI.
User Experience and Installation
Installation ease is an important consideration for many users. The MSI MPG A850GS is fully modular, allowing for more straightforward cable management and a cleaner build, which is particularly beneficial for gamers who wish to optimize airflow in their cases. The Thermaltake Smart 500W, while not fully modular, still supports two PCIe 6+2-pin connectors, making it versatile for various setups, although it may require more effort in cable management.
Target Audience
The MSI MPG A850GS is designed for gamers and power users who need a high-performance, efficient power supply capable of supporting demanding hardware. Its features cater specifically to those who may push their systems to the limit. In contrast, the Thermaltake Smart 500W is more suited for casual users or budget-conscious gamers who require a reliable power supply for standard gaming or office setups without the need for high wattage.
Which should you buy?
Choosing between the MSI MPG A850GS and the Thermaltake Smart 500W ultimately depends on your specific needs and budget. If you're building a high-performance gaming rig and require a robust power supply with long-term reliability, the MSI MPG A850GS is the superior choice, albeit at a higher price of $110.99. However, if you're looking for a budget-friendly option that still delivers reliable performance for standard gaming needs, the Thermaltake Smart 500W at $39.99 offers an attractive solution.
