SAMA Black 850W Power Supply - Fully Modular 80 Plus Gold Certified ATX 3.1 & PC vs Fasgear PCIe 5.0 GPU Power Cable Sleeved 70cm

Overview of the Products

In this comparison, we will examine the SAMA Black 850W Power Supply and the Fasgear PCIe 5.0 GPU Power Cable. The SAMA power supply is priced at C$89.99, while the Fasgear cable is significantly less at C$33.99. This price difference reflects the distinct roles these products play in a PC build, with the power supply being a critical component and the cable serving as an accessory to connect high-end graphics cards.

Design and Build Quality

The SAMA Black 850W Power Supply boasts a fully modular design, allowing users to connect only the cables necessary for their system. This approach not only simplifies installation but also enhances airflow and overall cable management. The use of flat cables contributes to a clean build appearance and optimal cooling performance. In contrast, the Fasgear PCIe 5.0 GPU Power Cable is designed specifically to connect high-end graphics cards like the RTX 3090 Ti and RTX 40 series. The cable is made with 16AWG tinned copper wires, which are known for stable voltage transmission and higher power output, though it is limited in compatibility to certain power supplies.

Compatibility

The SAMA Black 850W Power Supply is designed to meet the latest ATX 3.1 standards and features native PCIe 5.1 ports. This makes it compatible with high-end GPUs such as the RTX 3090 Ti and RTX 40 series, ensuring seamless performance. On the other hand, the Fasgear PCIe 5.0 GPU Power Cable is specifically compatible only with ASUS, EVGA, and Seasonic power supplies that have 8-pin (6+2) ports. This limitation means that while it excels in its niche, users must ensure their existing power supply matches these requirements to avoid compatibility issues.

Efficiency and Performance

The SAMA power supply is 80 PLUS Gold certified, achieving up to 91.15% efficiency at 50% load. This high efficiency translates to reduced energy waste and lower heat output, which is crucial for maintaining the longevity of components within a PC. The ECO fan with Fluid Dynamic Bearing technology further enhances cooling performance while operating quietly. Conversely, the Fasgear power cable supports up to 600W output, thanks to its construction with 16AWG copper wire. This allows it to deliver stable power to high-performance GPUs, although the cable itself does not provide efficiency ratings or cooling benefits since it is purely a connector.

Noise Levels

In terms of noise levels, the SAMA Black 850W Power Supply is designed for quiet operation, with noise levels as low as ≤20dB-A under heavy loads. This low noise output is particularly advantageous for users seeking a silent computing experience, especially in gaming or workstation environments. The Fasgear power cable, meanwhile, does not have a noise rating, as it is simply a passive component that connects the power supply to the GPU. Therefore, the noise performance is primarily determined by the power supply it connects to.

Warranty and Reliability

SAMA backs its 850W power supply with a 5-year warranty, underscoring its commitment to quality and reliability. This extended warranty period is an important consideration for users who want peace of mind regarding component longevity and performance. The Fasgear PCIe power cable, in contrast, does not specify a warranty period, which may raise questions about its long-term reliability. Users must consider that while the cable is designed for high-end GPUs, the lack of a warranty could be a drawback for some.

Use Case Scenarios

The SAMA Black 850W Power Supply is ideal for users building high-performance gaming rigs or workstations that require stable, efficient power delivery. Its compatibility with the latest GPU standards and high efficiency makes it a versatile choice for various builds. In contrast, the Fasgear PCIe 5.0 GPU Power Cable is best suited for users who already own a compatible power supply and need a reliable way to connect their high-end GPUs. It serves as a necessary accessory rather than a standalone solution, making it less versatile than the power supply itself.

Which should you buy?

Choosing between the SAMA Black 850W Power Supply and the Fasgear PCIe 5.0 GPU Power Cable ultimately depends on your needs. If you're in the market for a reliable, efficient power supply that supports the latest gaming technology, the SAMA power supply is the clear winner at C$89.99. However, if you already have a compatible power supply and need a high-quality cable for connecting a powerful GPU, the Fasgear cable at C$33.99 could be the right choice. Ultimately, both products serve essential but different functions in a high-performance PC build.
