Cooler Master V750 SFX Gold 750W Fully Modular vs SAMA White 650W Power Supply - Fully Modular 80

Overview of the Power Supplies

The Cooler Master V750 SFX Gold is priced at $161.80, while the SAMA White 650W is significantly more affordable at $62.99, making it about 61% cheaper. Both power supplies are fully modular and certified with 80 Plus Gold efficiency, ensuring effective power delivery. However, the V750 excels in power output with 750W compared to the SAMA's 650W, which may be crucial for high-performance builds.

Design and Form Factor

The Cooler Master V750 SFX Gold's design is tailored for mini-ITX builds, offering a compact solution without sacrificing performance. Its small form factor allows it to fit into smaller cases while providing 750W of power. On the other hand, the SAMA White is designed for standard ATX cases, appealing to users who prioritize traditional form factors. Its fully modular design and flat cables enhance cable management, promoting better airflow and a cleaner build.

Cooling and Noise Levels

The Cooler Master features a 92mm Fluid Dynamic Bearing (FDB) fan, delivering reliable cooling while maintaining low noise levels. This design allows the power supply to operate efficiently under load. Conversely, the SAMA White is equipped with a 120mm ECO fan that also utilizes Fluid Dynamic Bearing technology, ensuring quiet operation with noise levels as low as 20dB-A. Both units prioritize cooling, but the choice may depend on the specific noise tolerance and cooling requirements of your build.

Efficiency Ratings

Both power supplies boast 80 Plus Gold certification, guaranteeing high efficiency in power delivery. The Cooler Master V750 achieves 90% efficiency, while the SAMA White reaches up to 91.15% at 50% load, slightly edging out its competitor. This efficiency translates to lower energy costs and reduced heat output, which can prolong the lifespan of components. For users focused on energy efficiency, the SAMA White may have a slight advantage.

Compatibility with Modern GPUs

The Cooler Master V750 SFX Gold is ATX 3.1 and PCIe 5.1 ready, providing compatibility with the latest graphics cards and ensuring that your high-end components receive the power they require. Similarly, the SAMA White also supports ATX 3.1 and PCIe 5.1 standards, making it compatible with RTX 30 and 40 series GPUs. Both units are designed to handle modern gaming demands, but the V750's higher wattage may provide more headroom for overclocking or future upgrades.

Durability and Warranty

Cooler Master backs the V750 SFX Gold with a substantial 10-year warranty, underscoring its durability and reliability. The SAMA White, while offering a respectable 5-year warranty, may not instill the same level of confidence for long-term users. The use of high-quality Japanese capacitors in the SAMA White adds to its reliability, but the extended warranty of the Cooler Master might appeal to users who prioritize long-term investment.

Price Comparison

The price difference between these two power supplies is striking. At $161.80, the Cooler Master is about 61% more expensive than the SAMA White, which retails for $62.99. This significant price gap may influence users on a budget or those looking to build a cost-effective system without sacrificing quality. However, the V750’s higher price reflects its superior power output and longer warranty, which could justify the investment for some users.

Which should you buy?

Choosing between the Cooler Master V750 SFX Gold and the SAMA White 650W power supply ultimately hinges on your specific needs and budget. If you're building a high-performance mini-ITX system and desire the best efficiency, durability, and power output, the Cooler Master may be worth the higher price. However, if you're looking for a more budget-friendly option that still meets modern standards, the SAMA White offers excellent value for its price, particularly for those with moderate power requirements.
