Cooler Master V850 SFX Gold vs CORSAIR RM750e

Introduction to the Power Supply Showdown

In this comparison, we will assess two prominent power supplies: the Cooler Master V850 SFX Gold and the Corsair RM750e. The V850 SFX Gold is priced at £134.56, while the RM750e is significantly more affordable at £81.99. This analysis will delve into their specifications, features, and overall suitability for different builds, providing insights to help you make an informed decision.

Design and Form Factor

The Cooler Master V850 SFX Gold is specifically designed for small form factor (SFF) mini-ITX PC cases, boasting compact dimensions of 100 x 125 x 63.5 mm. This makes it a perfect fit for builders looking to optimise space without sacrificing power. In contrast, the Corsair RM750e does not highlight a specific form factor but is a fully modular power supply, allowing users to connect only the cables necessary for their builds. This feature can help with cable management and airflow in larger cases. If size is a critical factor in your build, the Cooler Master V850 SFX Gold has the edge.

Efficiency and Performance

Efficiency is a crucial consideration for power supplies, and the Cooler Master V850 SFX Gold shines with an 80 PLUS Gold certification, offering up to 90% efficiency under typical loading conditions. This high efficiency not only saves on utility costs but also reduces heat accumulation, enhancing overall performance. On the other hand, the Corsair RM750e does not specify an efficiency rating but is Intel ATX 3.1 certified, indicating it supports the latest power standards and can handle transient power excursions from GPUs. While both units are designed to provide reliable power, the Cooler Master offers a proven efficiency rating that could benefit energy-conscious users.

Cable Management

The Cooler Master V850 SFX Gold features fully modular cabling, allowing users to eliminate unnecessary cables from their builds, thus improving internal ventilation. It comes with a comprehensive selection of cables, including eight SATA and four PCI-e 6+2 Pin connectors. Corsair's RM750e is also fully modular, which provides the same benefits of custom cable management. Both units excel in this area, but the Cooler Master’s extensive cable offerings give it a slight advantage for more complex builds requiring numerous connections.

Noise Levels

When it comes to noise levels, the Cooler Master V850 SFX Gold utilises a 92mm fluid dynamic bearing (FDB) fan, designed to keep both temperature and noise to a minimum. It also features a semi-fanless mode when under 15% maximum operating load, enhancing its quiet operation during low demand. In contrast, the Corsair RM750e is equipped with a 120mm rifle bearing fan that is engineered to maintain low noise levels, even at full load. For users prioritising a quiet system, both options are commendable, but the semi-fanless mode of the Cooler Master may offer additional quiet operation during less intensive tasks.

Build Quality and Durability

Durability is essential for power supplies, and the Cooler Master V850 SFX Gold is built with 100% Japanese capacitors, ensuring long-term performance and reliability. Additionally, it comes with a generous 10-year warranty, reflecting the brand's confidence in its product's longevity. The Corsair RM750e also features 105°C-rated capacitors, which contribute to its stability and reliability. However, it does not specify a warranty period, which could be a consideration for potential buyers focused on long-term durability. Overall, the Cooler Master has a clear advantage in terms of warranty and component quality.

Price and Value

Pricing is a significant factor in any purchasing decision. The Cooler Master V850 SFX Gold is priced at £134.56, while the Corsair RM750e is more budget-friendly at £81.99. Despite the higher cost, the Cooler Master offers superior features such as a higher efficiency rating, extensive cabling options, and a longer warranty. For users with a tighter budget or less demanding power needs, the Corsair may offer sufficient performance at a more accessible price point. However, for those looking for premium quality and efficiency, the Cooler Master justifies its higher price.

User Experience and Installation

Both the Cooler Master V850 SFX Gold and Corsair RM750e are designed for ease of installation. The fully modular nature of both products allows users to connect only the cables they need, simplifying the installation process. The Cooler Master’s compact design makes it easier to fit into smaller cases, while the Corsair’s capabilities for larger builds ensure flexibility. Users should find both products straightforward to install, but the choice will largely depend on the specific case dimensions and cable management preferences.

Which should you buy?

Choosing between the Cooler Master V850 SFX Gold and the Corsair RM750e ultimately depends on your specific needs and budget. If you require a compact power supply for a small form factor build and value efficiency, durability, and extensive cabling options, the Cooler Master V850 SFX Gold is an excellent choice despite its higher price. Conversely, if you are looking for a cost-effective power supply that still delivers reliable performance for a standard build, the Corsair RM750e could be the way to go. Each power supply has its strengths, making it essential to consider what features matter most to you before making a decision.
