CORSAIR SF850 vs ESGAMING 700W Non Modular Power Supply with Low-Noise 120mm Fan ATX PSU

Overview of the Products

When looking for a power supply, the choice often boils down to the specific needs of your system. The CORSAIR SF850, priced at C$279.99, offers high-end features suited for compact builds, while the ESGAMING 700W Non Modular Power Supply comes in at a budget-friendly C$59.89, providing basic functionality for general use. This article compares both options to help you decide which power supply is right for you.

Performance and Efficiency

The CORSAIR SF850 boasts an impressive 80 PLUS Platinum certification, indicating exceptional energy efficiency. This certification means that the unit operates at a minimum of 92% efficiency at typical loads, translating to less wasted energy and lower electricity bills. In contrast, the ESGAMING power supply does not specify an efficiency rating, which may suggest lower performance, particularly under load. Therefore, for users prioritizing energy efficiency and performance, the CORSAIR SF850 is a clear leader.

Form Factor and Design

In terms of form factor, the CORSAIR SF850 features a compact SFX design that is ideal for small form-factor PCs. This feature is particularly beneficial for those looking to save space without compromising on power. The ESGAMING power supply, on the other hand, utilizes a standard ATX design. While the ATX form factor is widely compatible with most cases, it may not suit builds where space is at a premium. Thus, if your build requires a compact solution, the CORSAIR SF850 is more advantageous.

Modular vs. Non-Modular

One significant difference between these two power supplies is their cable management systems. The CORSAIR SF850 is fully modular, allowing users to connect only the cables they need, which results in better airflow and a cleaner build. Conversely, the ESGAMING power supply is non-modular, meaning all cables come pre-installed. This can lead to excess cable clutter within the case, potentially impacting airflow and aesthetics. For those who value a neat and efficient setup, the modularity of the CORSAIR SF850 provides a distinct benefit.

Cooling Solutions

Cooling is an essential aspect of any power supply, and both units feature different approaches. The CORSAIR SF850 is equipped with a 92mm PWM cooling fan that operates quietly due to its fluid dynamic bearing. This design not only ensures effective cooling but also keeps noise levels to a minimum. In comparison, the ESGAMING power supply features a larger 120mm fan, claimed to provide virtually silent operation at low loads. While the larger fan might sound appealing, its performance under higher loads is not specified, making it difficult to evaluate its effectiveness fully. Hence, users who prioritise quiet operation and reliable cooling under load may lean towards the CORSAIR SF850.

Safety Features

Safety is paramount when selecting a power supply, and both models offer comprehensive protection features. The ESGAMING power supply lists several protective measures, including Over Voltage Protection (OVP), Under Voltage Protection (UVP), and Over Temperature Protection (OTP), which help safeguard critical system components. The CORSAIR SF850, while not explicitly detailing its safety features, is built with high-quality 105°C rated Japanese capacitors, ensuring durability and consistent performance. Although both units provide safety mechanisms, the extensive list of protections in the ESGAMING might appeal to budget-conscious users seeking peace of mind.

Compatibility

Compatibility is another crucial aspect to consider. The CORSAIR SF850 is ATX 3.0 compliant and PCIe 5.0 ready, supporting the latest standards and ensuring future-proofing for users with newer components. The ESGAMING power supply also claims high compatibility, featuring multiple connectors, including an 8-pin CPU connector that can be split into a 4+4 connector. However, its lack of mention regarding newer standards may mean it’s less future-proof. Therefore, for users looking to invest in their systems for the long term, the CORSAIR SF850 is the more compatible option.

Price and Value

When it comes to price, the ESGAMING power supply is significantly more affordable at C$59.89 compared to the C$279.99 price tag of the CORSAIR SF850. The lower price point makes the ESGAMING an attractive option for those on a budget or for users with less demanding power needs. However, it's important to consider the value offered by each power supply. The CORSAIR SF850, while more expensive, delivers superior efficiency, modularity, and advanced features that can benefit high-performance systems. Therefore, while the ESGAMING offers great value for basic setups, the CORSAIR SF850 justifies its higher price through its premium features.

Which should you buy?

Choosing between the CORSAIR SF850 and the ESGAMING 700W Non Modular Power Supply ultimately depends on your specific needs. If you are building a compact, high-performance system and are willing to invest more for superior efficiency, modularity, and future-proofing, the CORSAIR SF850 is the better choice. On the other hand, if you are on a tight budget and require a basic power supply for a less demanding system, the ESGAMING power supply offers excellent value at a fraction of the cost. Assess your requirements carefully to determine which power supply will best suit your build.
