CORSAIR SF850 vs Lian Li SP850 V2 Gold 850 Watt SFX Form Factor Power Supply

Overview of the Products

The CORSAIR SF850 and the Lian Li SP850 V2 Gold are two compact SFX power supplies designed for high-performance systems. The CORSAIR SF850 is priced at C$279.99, while the Lian Li SP850 V2 Gold offers a more budget-friendly option at C$194.23. Both power supplies cater to users looking for reliability and efficiency in smaller form factors, but they present distinct features that may appeal to different users.

Build Quality and Design

Both power supplies boast a fully modular design, allowing users to connect only the cables they need for their specific setups. The CORSAIR SF850 features Type-5 Micro-Fit PSU connectors, which are designed to save space and facilitate tidy cable management, while the Lian Li SP850 V2 Gold emphasizes reliability with its two-tone 12V-2x6 power cable that provides clear visual cues for safer connections. The Lian Li model has been redesigned to meet the ≤63.5mm SFX size specification, ensuring compatibility and efficient cooling, which is crucial for compact builds.

Power Ratings and Efficiency

The CORSAIR SF850 holds a notable 80 PLUS Platinum rating, indicating exceptional energy efficiency. This rating signifies that it operates at up to 92% efficiency under typical loads, which can lead to lower electricity costs over time. In contrast, the Lian Li SP850 V2 Gold is ATX 3.1 certified and provides 850 watts of power, but it does not specify an efficiency rating comparable to the Platinum standard. This distinction can be significant for users focused on energy savings and environmental considerations.

Cooling Performance

Cooling performance is critical in compact systems, and both power supplies incorporate a 92mm fan design. The CORSAIR SF850 utilises a PWM cooling fan that is engineered for low-noise operation, thanks to its fluid dynamic bearing. The Lian Li SP850 V2 Gold also employs a premium 92mm FDB fan for quiet thermal performance. However, the Lian Li model specifically highlights its upgraded fan for quieter operation and increased longevity, which could appeal to users prioritizing silent computing.

Durability and Reliability

Durability is paramount in power supplies, and both models are designed with high-quality components. The CORSAIR SF850 is equipped with 105°C rated Japanese capacitors, contributing to its reliability and stable power delivery. Meanwhile, the Lian Li SP850 V2 Gold features upgraded Japanese electrolytic capacitors, promising stable and reliable power as well. Additionally, the Lian Li model offers a 10-year hardware protection, which is notable as it provides peace of mind for long-term use.

Compatibility and Future-Proofing

When it comes to compatibility, both power supplies are ATX compliant, ensuring they can support modern hardware. The CORSAIR SF850 is ATX 3.0 compliant and PCIe 5.0 ready, which may be advantageous for users looking to integrate the latest graphics cards and components. The Lian Li SP850 V2 Gold, while ATX 3.1 certified, also supports PCIe Gen 5.0 platforms. This future-proofing is vital for gamers and PC builders who want to invest in components that will last.

User Experience and Installation

The user experience is often shaped by how easy it is to install and manage cables. The fully modular design of both the CORSAIR SF850 and Lian Li SP850 V2 Gold allows for straightforward installation, as users can select only the necessary cables. However, the CORSAIR model's Type-5 Micro-Fit PSU connectors may provide a slight edge in compact builds by reducing clutter and enhancing cable management. Ultimately, both power supplies offer an excellent installation experience, but the details in cable design can influence user preferences.

Which should you buy?

Choosing between the CORSAIR SF850 and the Lian Li SP850 V2 Gold ultimately depends on your specific needs and budget. The CORSAIR SF850 stands out with its 80 PLUS Platinum efficiency rating and high-quality Japanese capacitors, making it a reliable choice for users seeking top-tier performance and energy savings. However, at C$194.23, the Lian Li SP850 V2 Gold provides a more economical option while still delivering a solid 850 watts of power and impressive reliability, backed by a 10-year warranty. For those prioritising performance and efficiency, the CORSAIR SF850 is the better option, while budget-conscious users will find the Lian Li SP850 V2 Gold to be a compelling choice.
