CORSAIR RM850e vs Cooler Master V850 SFX Gold White Edition Full Modular

Price Comparison

The CORSAIR RM850e is priced at C$184.99, making it the more affordable option compared to the Cooler Master V850 SFX Gold White Edition, which retails at C$220.99. The price difference of C$36 highlights a significant factor for budget-conscious consumers. While both power supplies offer premium features, the cost-effectiveness of the RM850e may appeal to those looking to maximise value without compromising on performance. This lower price point could be particularly enticing for users who are building a system on a tighter budget or who don't require the specific features offered by the Cooler Master model.

Power Efficiency

In terms of power efficiency, the Cooler Master V850 SFX Gold White Edition boasts an 80 PLUS Gold certification, ensuring a typical efficiency of 90% under normal operating conditions. This level of efficiency is crucial for minimising energy waste and reducing electricity costs over time. On the other hand, while the CORSAIR RM850e does not explicitly state an efficiency rating comparable to the 80 PLUS Gold, it is Intel ATX 3.1 certified and designed to handle the demands of modern hardware, including support for PCIe 5.1. Although both power supplies are efficient, the Cooler Master unit has a clear advantage in terms of its official efficiency rating, making it a better choice for users prioritising energy savings.

Modularity and Installation

The CORSAIR RM850e features fully modular cabling, allowing users to connect only the cables necessary for their specific build. This reduces clutter and enhances airflow within the case. Similarly, the Cooler Master V850 SFX Gold White Edition also offers full-modular cabling, which improves overall efficiency and thermal performance. However, it also stands out with its SFX form factor, making it compatible with mini-ITX cases, and includes an SFX-to-ATX bracket for installation in standard ATX cases. This versatility gives the Cooler Master unit a unique edge, especially for users looking to build compact systems with limited space.

Cooling Solutions

Both power supplies employ effective cooling solutions to maintain optimal performance. The CORSAIR RM850e utilises a 120mm rifle bearing fan with a specially calculated fan curve, which keeps fan noise to a minimum, even under full load. This design is essential for users who prefer a quiet computing experience. In contrast, the Cooler Master V850 SFX Gold White Edition features a fluid dynamic bearing (FDB) fan, known for its longevity and quieter operation. While both cooling systems are designed to operate quietly, the FDB fan of the Cooler Master model may offer long-term reliability and lower noise levels, giving it a slight advantage in thermal management.

Build Quality and Components

The CORSAIR RM850e is built with 105°C-rated capacitors, ensuring steady and reliable power delivery, which is crucial for the longevity of high-performance components. This rating indicates that the power supply can handle higher temperatures without degrading performance. The Cooler Master V850 SFX Gold White Edition also emphasises quality with its use of 16 AWG PCI-e cables, which allow for higher currents and improved safety. While both power supplies are built with high-quality materials, the specific focus on different aspects—temperature tolerance for the RM850e and cable quality for the V850 SFX—shows that both brands prioritise reliability, but in diverse ways.

Compatibility

When it comes to compatibility, the Cooler Master V850 SFX Gold White Edition is specifically designed for SFX form factor cases, making it an ideal choice for mini-ITX builds. It also includes an SFX-to-ATX bracket, allowing installation in larger ATX cases, thus broadening its compatibility. In contrast, the CORSAIR RM850e is designed in the standard ATX format, catering to traditional builds. While both power supplies support a wide range of systems, the Cooler Master model's flexibility in fitting into both SFX and ATX cases provides it with a practical advantage for users considering various system configurations.

Brand Reputation and Warranty

Both Corsair and Cooler Master have established themselves as reputable brands in the power supply market. The CORSAIR RM850e benefits from Corsair's strong reputation for quality and customer service, while the Cooler Master V850 SFX Gold White Edition is backed by a ten-year warranty, reflecting confidence in its durability and performance. This long warranty period can be a crucial deciding factor for potential buyers, as it not only indicates the brand's trust in its product but also offers peace of mind for users making a long-term investment in their power supply.

Which should you buy?

Choosing between the CORSAIR RM850e and the Cooler Master V850 SFX Gold White Edition ultimately depends on your specific needs and preferences. If you are looking for a budget-friendly option that offers reliable performance, the RM850e at C$184.99 is an excellent choice. However, if you require a power supply that excels in efficiency, versatility, and long-term reliability, the Cooler Master V850 SFX Gold at C$220.99 may be worth the additional investment. Consider your build requirements, space constraints, and long-term goals to determine which power supply aligns best with your needs.
