PCCOOLER PSU Fully Modular Power Supply, 850W ATX vs SAMA White 650W Power Supply - Fully Modular 80

Price Comparison

The PCCOOLER PSU Fully Modular Power Supply is priced at $79.99, while the SAMA White 650W Power Supply comes in at $62.99. This makes the SAMA option about 17% cheaper than the PCCOOLER model. If budget is a primary concern, the SAMA power supply offers significant savings, which is particularly beneficial for those looking to build a high-performance system without overspending. However, the additional features and power capacity of the PCCOOLER may justify its higher price for some consumers.

Power Output

When it comes to power output, the PCCOOLER offers 850W compared to the 650W provided by the SAMA model. This 200W difference gives the PCCOOLER a distinct advantage for users who require more power for high-end components. The additional wattage can support more demanding systems, particularly those with multiple GPUs or power-hungry CPUs. For gamers or professionals using high-performance hardware, the increased capacity of the PCCOOLER may be a crucial factor.

Modular Design

Both power supplies feature a fully modular design, allowing users to connect only the cables needed for their specific setup. The PCCOOLER utilizes ultra-flexible shark-pattern cables, while the SAMA employs flat cables for streamlined management. This modularity leads to improved airflow and reduced clutter in the case. Although both designs are effective, the aesthetic preference for cable style may sway some users toward one product over the other.

Efficiency Ratings

The PCCOOLER is 80 Plus Gold Certified, achieving up to 92% conversion efficiency under typical loads, while the SAMA also holds an 80 Plus Gold Certification but offers a slightly lower efficiency rating of up to 91.15% at 50% load. This difference may seem minor, but the higher efficiency of the PCCOOLER could result in lower electricity bills and reduced heat output over time. Consumers who prioritize energy efficiency may find the PCCOOLER to be the better choice in this aspect.

Cooling Solutions

In terms of cooling, the PCCOOLER features a temperature-controlled 120mm hydraulic bearing fan that operates quietly under low loads. The SAMA model also includes a 120mm ECO fan with Fluid Dynamic Bearing technology, promising noise levels as low as 20dB-A even under load. Both cooling solutions are designed to maintain optimal performance and minimize noise. However, the specifics of each fan's operation might appeal to different users depending on their noise tolerance and cooling preferences.

Compatibility with GPUs

The PCCOOLER is designed to support the latest GPUs, equipped with a native 12V-2×6 PCIe 5.1 connector, which eliminates the need for adapters when using modern high-performance graphics cards. In contrast, the SAMA also supports PCIe 5.1 and is compatible with RTX 30/40 series GPUs. Both power supplies are well-equipped for current and future graphics card technologies, making them suitable choices for gamers looking to invest in high-end graphics performance.

Warranty and Reliability

Both the PCCOOLER and SAMA power supplies come with a 5-year warranty, reflecting a commitment to reliability and customer satisfaction. The use of high-quality Japanese capacitors in both models further ensures stable power delivery and longevity. This similar warranty period and capacitor quality suggest that both brands stand behind their products, which is an essential consideration for consumers looking for long-term investments in their systems.

Which should you buy?

Choosing between the PCCOOLER PSU Fully Modular Power Supply and the SAMA White 650W Power Supply largely depends on your specific needs and budget. If you require a higher wattage and slightly better efficiency for a more demanding setup, the PCCOOLER at $79.99 is the way to go. However, if you are looking for a more budget-friendly option without sacrificing essential features, the SAMA at $62.99 is a solid choice. Ultimately, both power supplies offer excellent performance and reliability, making either a worthy addition to your build.
