Price Comparison

The Cooler Master V750 SFX Gold retails for $161.80, while the CORSAIR RM850e is priced at $94.99. This makes the CORSAIR model approximately 41% cheaper than the Cooler Master. If you are looking for a budget-friendly option, the RM850e certainly stands out. However, the V750 SFX Gold offers features that may justify its higher price for users seeking specific functionality.

Power Output and Efficiency

In terms of power output, the Cooler Master V750 SFX Gold provides 750 watts, while the CORSAIR RM850e offers 850 watts. Although the RM850e has a higher wattage, both power supplies claim high efficiency. The V750 SFX Gold boasts an 80+ Gold efficiency rating, ensuring about 90% efficiency, while the RM850e also has a Cybenetics Gold efficiency rating. This means both units are designed to minimize energy waste, making them excellent choices for energy-conscious users.

Form Factor and Compatibility

The Cooler Master V750 SFX Gold is designed specifically for small form factor builds, making it an ideal choice for mini-ITX cases. Its compact dimensions and SFX design provide flexibility in system builds. On the other hand, the CORSAIR RM850e is an ATX power supply, making it suitable for a wider range of cases, including standard ATX and larger configurations. This difference could be a deciding factor if you're building a compact system versus a standard one.

Cable Management

Both power supplies are fully modular, which means users can connect only the cables they need. The Cooler Master V750 SFX Gold features customized short cables and includes a 90° 12VHPWR PCIe 5.1 connector to reduce clutter and improve airflow. The RM850e also emphasizes ease of installation with its fully modular design, allowing builders to streamline their setups. The choice here will depend on the specific needs of your build and the space available for cable routing.

Cooling and Noise Levels

The V750 SFX Gold is equipped with a 92mm Fluid Dynamic Bearing fan, which ensures reliable cooling while maintaining a low noise level. In contrast, the CORSAIR RM850e uses a 120mm rifle bearing fan, designed to keep noise to a minimum even under full load. Both power supplies prioritize quiet operation, making them suitable for users who want a silent computing experience. However, the larger fan in the RM850e could provide better cooling performance, especially in high-demand scenarios.

Warranty and Reliability

The Cooler Master V750 SFX Gold comes with a generous 10-year warranty, indicating the brand’s confidence in its product's longevity and reliability. The CORSAIR RM850e offers a 7-year warranty, which is still quite substantial but shorter than that of the V750. The longer warranty period for the V750 could provide peace of mind for users looking for durability and long-term usage from their power supply.

Target Audience

The Cooler Master V750 SFX Gold is aimed at users who require a compact, high-performance unit for mini-ITX builds, particularly those who value efficiency and long-term reliability. The CORSAIR RM850e, being more budget-friendly and versatile, appeals to a broader audience, including gamers and professionals looking for a reliable power supply without breaking the bank. Your choice will depend on your specific use case and budget constraints.

Which should you buy?

Ultimately, your decision between the Cooler Master V750 SFX Gold and the CORSAIR RM850e will hinge on your needs. If you are building a small form factor system and prioritize 80+ Gold efficiency and a longer warranty, the Cooler Master V750 SFX Gold is worth the extra investment. However, if you are looking for a more budget-friendly option that still offers solid performance and features, the CORSAIR RM850e is an excellent choice. Each has its strengths, so consider your specific requirements before making a final decision.
