Lian Li SP850 V2 Gold 850 Watt SFX Form Factor Power Supply vs CORSAIR CX750M

Pricing Comparison

The Lian Li SP850 V2 Gold is priced at C$194.23, significantly higher than the Corsair CX750M, which retails for C$124.99. This price difference of C$69.24 reflects the premium features and capabilities of the Lian Li model. While the Corsair offers good value with its semi-modular design and reliable performance, the additional cost of the Lian Li can be justified by its extensive feature set, including ATX 3.1 certification and a higher wattage output. For budget-conscious consumers, the Corsair CX750M presents a compelling option without sacrificing essential power supply functionality.

Power Output and Efficiency

The Lian Li SP850 V2 Gold delivers a robust 850 watts of power, while the Corsair CX750M provides 750 watts. This 100-watt difference means that the Lian Li can support more demanding hardware, particularly high-performance graphics cards and multiple peripherals. The Lian Li's efficiency is further enhanced by its ATX 3.1 certification, which ensures compatibility with the latest power standards and optimises power delivery. Conversely, the CX750M, although slightly lower in wattage, is still a solid choice for mid-range builds, making it suitable for gamers and content creators who do not require the utmost power.

Design and Form Factor

The Lian Li SP850 V2 Gold features an SFX form factor, designed specifically for compact builds, making it an ideal choice for small form-factor cases. In contrast, the Corsair CX750M is semi-modular and comes in a standard ATX size, which may not fit into tighter spaces as easily as the SFX Lian Li. This difference in design can affect installation ease and overall system layout, especially for users looking to maximise space in a compact gaming rig. The Lian Li also incorporates a premium 92mm low-noise fan, contributing to quieter operation compared to the 120mm fan in the Corsair, which is noted for its near-silent performance under low and medium loads.

Modular Options

Lian Li's SP850 V2 Gold is a fully modular power supply, allowing users to connect only the cables they need, which helps to reduce clutter and improve airflow within the case. The Corsair CX750M, on the other hand, offers a semi-modular design where the main power cables are pre-attached, while the remaining cables are modular. This setup provides some flexibility but does not match the complete customisation available with the Lian Li. Users who prioritise a clean and efficient build might find the fully modular design of the Lian Li more appealing, especially when considering the impact on thermal performance and cable management.

Cooling Performance

Cooling is crucial for maintaining system stability, and both power supplies feature advanced fan technology. The Lian Li SP850 V2 Gold is equipped with a 92mm Fluid Dynamic Bearing (FDB) fan that is specifically designed for low noise and efficient thermal performance. In comparison, the Corsair CX750M has a 120mm low-noise fan that remains silent under low to medium loads. While both models aim for quiet operation, the choice of fan size and technology may appeal to different users based on their cooling requirements and case configurations. The SP850 V2 Gold's fan is optimised for high-performance cooling in compact environments, which could be beneficial for small builds.

Compatibility and Standards

Both power supplies are compliant with modern standards, including ATX 3.1, ensuring reliable power delivery and compatibility with the latest hardware. The Lian Li SP850 V2 Gold supports PCIe Gen 5.0, which is essential for users looking to utilise the latest graphics cards, as it resists transient power spikes effectively. The Corsair CX750M also supports the latest PCIe 5.1 standard, making it a viable option for current and upcoming graphics cards. This adherence to modern standards means that both power supplies can adequately support high-performance components, although the Lian Li has the edge in terms of next-gen GPU compatibility.

Warranty and Reliability

Reliability is a critical factor when choosing a power supply, and the Lian Li SP850 V2 Gold offers a substantial 10-year hardware protection warranty. This extended warranty reflects the company's confidence in the durability and performance of their product. In contrast, while the Corsair CX750M is a reputable choice, the warranty details are not specified in the available data, which may leave potential buyers wanting more assurance. The longer warranty on the Lian Li could provide peace of mind for users investing in high-end systems, suggesting a commitment to long-term reliability.

Which should you buy?

Choosing between the Lian Li SP850 V2 Gold and the Corsair CX750M ultimately depends on your specific needs and budget. If you require higher wattage, advanced features like full modularity, and a longer warranty, the Lian Li SP850 V2 Gold is the superior choice, albeit at a higher price of C$194.23. However, for those with a more modest budget or who are building a mid-range system, the Corsair CX750M at C$124.99 offers excellent value without compromising on essential performance. Both power supplies are reliable options that cater to different user requirements, making the decision largely a matter of personal preference and system demands.
