SAMA Black 850W Power Supply - Fully Modular 80 Plus Gold Certified ATX 3.1 & PC vs Programmable DC Power Supply

Overview of the Products

In this comparison, we are examining the SAMA Black 850W Power Supply and the Programmable DC Power Supply by Kiprim. The SAMA power supply is priced at C$89.99, while the Kiprim model comes at a significantly higher price of C$159.99. Each product serves distinct purposes within the realm of power supplies, catering to different user needs, from gaming rigs to more versatile laboratory applications.

Design and Build Quality

The SAMA Black 850W Power Supply features a fully modular design that promotes streamlined cable management. This design allows users to connect only the necessary cables, which not only keeps the build clean but also enhances airflow for optimal cooling. On the other hand, the Programmable DC Power Supply offers a robust build with a multi-function display that includes a 2.8-inch colour LCD. This display shows real-time voltage and current readings, making it highly functional for users who require precise measurements. The SAMA power supply’s design focuses on aesthetic appeal and efficiency, while the Kiprim model prioritizes functionality and control.

Performance and Efficiency

The SAMA Black 850W Power Supply boasts an impressive efficiency rating of up to 91.15% at 50% load, thanks to its 80 PLUS Gold certification. This high efficiency reduces energy waste and heat output, contributing to system stability and longevity. In contrast, the Programmable DC Power Supply supports a maximum output voltage of 30V and current of 10A, allowing for versatile applications in various settings. While the SAMA excels in efficiency for gaming setups, the Kiprim model is more adaptable for experimental and lab scenarios where different voltage and current settings are necessary.

Compatibility

Compatibility is a critical aspect of power supplies, and the SAMA Black 850W Power Supply stands out with its ATX 3.1 and PCIe 5.1 compatibility. This feature ensures that it can seamlessly support high-end graphics cards like the RTX 3090 Ti and the RTX 40 series, making it a perfect choice for gamers and professionals. Conversely, the Programmable DC Power Supply is designed to operate across a wide voltage range (0-30V), making it suitable for various electronic devices and projects. Each product excels in its domain: the SAMA for PC builds and the Kiprim for broader electronic applications.

Cooling and Noise Levels

When it comes to cooling and noise management, the SAMA Black 850W Power Supply is equipped with a 120mm ECO fan featuring Fluid Dynamic Bearing (FDB) technology, which operates at noise levels as low as 20dB-A. This ensures that the power supply remains quiet even under significant loads, making it ideal for gaming environments where noise can be distracting. The Programmable DC Power Supply, while not explicitly mentioning noise levels, includes an intelligent fan cooling system to maintain optimal operating temperatures. However, the SAMA’s focus on low noise operation provides an edge for users prioritising quiet performance.

Safety Features

Safety features are paramount in any power supply, and both products offer a range of protections. The SAMA Black 850W Power Supply includes premium Japanese capacitors for stable power delivery, contributing to long-term reliability. In contrast, the Programmable DC Power Supply comes with multiple built-in protections, including overvoltage and overcurrent safeguards, as well as overheat protection at 85°C. These features make the Kiprim model a secure choice for experimental settings where power fluctuations may occur, while the SAMA is more focused on high-performance reliability for gaming.

Warranty and Support

Warranty and support can significantly influence purchasing decisions. The SAMA Black 850W Power Supply provides a generous 5-year warranty, reflecting confidence in its durability and performance. This long warranty period is particularly appealing to users investing in high-end components. Meanwhile, the Programmable DC Power Supply offers a 12-month warranty, which, while standard, may seem less appealing compared to the extended coverage of the SAMA. The longer warranty of the SAMA suggests a commitment to product quality and consumer satisfaction.

Price Comparison

Price is a significant factor for many consumers. The SAMA Black 850W Power Supply is attractively priced at C$89.99, providing a solid option for gamers and PC builders. In contrast, the Programmable DC Power Supply is priced at C$159.99, which reflects its multifunctional capabilities but may deter budget-conscious buyers. The price difference of C$70 indicates the SAMA's position as a more accessible choice for those primarily focused on building or upgrading their gaming systems.

Which should you buy?

Ultimately, the choice between the SAMA Black 850W Power Supply and the Programmable DC Power Supply by Kiprim depends on your specific needs. If you are looking for a reliable, efficient power supply for a gaming rig or high-performance PC, the SAMA offers superior efficiency, lower noise levels, and a longer warranty at a more affordable price. However, if you require a versatile power supply for a variety of electronic projects and appreciate features like programmable outputs and multiple protections, the Kiprim model may be worth the investment despite its higher price. Therefore, assess your priorities and choose the product that best fits your requirements.
