SAMA B850 850W ATX Power Supply vs ESGAMING 650W Non Modular Power Supply with Low-Noise 120mm Fan ATX PSU

Price Comparison

When considering the price, the SAMA B850 850W ATX Power Supply is more expensive at C$74.99 compared to the ESGAMING 650W Non Modular Power Supply, which retails for C$55.99. This represents a price difference of C$19.00, with the SAMA being approximately 34% more expensive. The higher price of the SAMA reflects its capabilities, including a significant power output of 850W, making it suitable for high-performance systems. In contrast, the ESGAMING offers a lower power output of 650W but is still a reasonable option for budget-conscious consumers looking for reliable performance.

Power Output and Efficiency

The SAMA B850 boasts an impressive power output of 850W, designed to support high-end GPUs like the RTX 4090/50 series. It also features 80 PLUS Bronze certification, indicating over 85% efficiency at typical load, which can lead to energy savings over time. On the other hand, the ESGAMING 650W provides sufficient power for mid-range systems but lacks the efficiency certification that the SAMA possesses. Users of the ESGAMING can expect solid performance, but the SAMA’s capability to handle more demanding hardware and its energy efficiency make it a stronger contender in this regard.

Cable Management and Aesthetics

In terms of cable management, the SAMA B850 comes with sleek black flat cables, which not only enhance airflow within the case but also improve the overall aesthetics of the build. Effective cable management can significantly impact both cooling performance and visual appeal. Conversely, the ESGAMING features non-modular cables that are pre-installed. While they are designed in a flat style to avoid the typical “ketchup and mustard” colour scheme, the lack of modularity may make for a more cluttered build, limiting airflow and aesthetic flexibility.

Cooling Solutions

Cooling performance is a critical factor for power supplies, and both products offer effective solutions. The SAMA B850 is equipped with a temperature-controlled fan that ensures quiet operation while maintaining optimal cooling performance, making it an excellent choice for users looking for a silent system. Meanwhile, the ESGAMING features a 120mm large fan designed for virtually silent operation at low loads, which is ideal for maintaining a quieter environment. However, the SAMA’s advanced cooling technology might provide more consistent cooling under heavy loads, making it better suited for high-demand scenarios.

Protection Features

Regarding safety and protection features, both the SAMA B850 and the ESGAMING include comprehensive protection mechanisms. The SAMA comes with OVP, OCP, OPP, and SCP protections, ensuring that your critical components are safeguarded against overvoltage, overcurrent, and short circuits. The ESGAMING also offers heavy-duty protections, including OVP, UVP, OPP, SCP, OCP, and OTP, which suggests a strong focus on component safety. Both power supplies provide peace of mind, but the additional protections in the SAMA B850 may appeal to users with more expensive hardware.

Compatibility and Form Factor

Compatibility is essential when selecting a power supply, and both the SAMA B850 and ESGAMING 650W are designed with standard ATX form factors, ensuring they fit most cases. The ESGAMING offers a wide range of connectors, including an 8-pin CPU connector that can be split into a 4+4 connector and an 8-pin PCIe connector that can be split into a 6+2 connector, making it versatile for various builds. Although the SAMA does not mention specific connectors, its higher wattage suggests it can support a broader range of hardware configurations, particularly for users looking to build high-end systems.

Brand Reputation and Warranty

Brand reputation and warranty are crucial considerations for many buyers. SAMA offers a 3-year warranty with its B850 model, providing reassurance to users regarding the longevity and reliability of their purchase. ESGAMING, while not specifying its warranty period, is known for delivering quality products at competitive prices. However, the length of the warranty can often reflect a brand's confidence in its product, and SAMA's warranty may suggest a higher commitment to customer satisfaction and product durability.

Which should you buy?

Ultimately, your choice between the SAMA B850 850W ATX Power Supply and the ESGAMING 650W Non Modular Power Supply will depend on your specific needs and budget. If you require higher wattage for a demanding gaming rig and value efficiency and aesthetics, the SAMA B850 is worth the extra investment at C$74.99. However, if you are looking for a budget-friendly option for a mid-range setup, the ESGAMING at C$55.99 offers solid performance and adequate safety features. Consider your power requirements, budget constraints, and the importance of features like efficiency and cooling when making your decision.
