Lian Li SP750 V2 Gold vs Seasonic Focus GX 850W Power Supply ATX 3.1 PCIe

Overview of Power Supplies

When comparing the Lian Li SP750 V2 Gold 750 Watt SFX Form Factor Power Supply and the Seasonic Focus GX 850W Power Supply, both units stand out for their high efficiency and modern connectivity features. The Lian Li power supply is priced at $124.99, while the Seasonic is available for $139.99, making the Lian Li about 10.7% cheaper. This article will delve into various aspects of both power supplies, helping you determine which is the better choice for your needs.

Design and Form Factor

The Lian Li SP750 V2 is designed in a compact SFX form factor, making it ideal for small form factor builds. This design allows for efficient cooling while fitting into tight spaces. On the other hand, the Seasonic Focus GX is an ATX power supply, which generally offers a larger footprint. While ATX PSUs can provide more power, the Lian Li’s compact design could be more appealing for users with space constraints. Therefore, if you're building a compact system, the Lian Li's form factor gives it a significant advantage.

Efficiency Ratings

Both power supplies boast impressive efficiency ratings, with the Lian Li SP750 V2 achieving an 80 PLUS Gold certification, while the Seasonic Focus GX goes a step further with Cybenetics Platinum certification. The Platinum rating indicates that the Seasonic unit operates at a slightly higher efficiency under load, potentially resulting in lower electricity costs over time. However, the difference may not be substantial for typical usage, but for those seeking maximum efficiency, the Seasonic could be the better option.

Cooling Solutions

The Lian Li SP750 V2 features a 92mm Fluid Dynamic Bearing (FDB) fan, which is designed for quiet operation while maintaining effective cooling. In contrast, the Seasonic Focus GX utilizes a larger 135mm FDB fan, allowing for better airflow and quieter performance. The larger fan in the Seasonic model could lead to more efficient cooling under heavy loads, making it preferable for high-performance systems or extended use. If noise levels are a primary concern, the Seasonic’s larger fan may provide a better solution.

Modular Cabling

Both power supplies are fully modular, allowing users to only connect the cables necessary for their system. This feature not only simplifies installation but also improves airflow within the case by reducing cable clutter. The Lian Li SP750 V2 includes a native 12V-2x6 connector, enhancing compatibility with modern graphics cards. The Seasonic Focus GX also features a native 12V-2x6 connector, ensuring it is equipped for the latest hardware. This parity in modularity and connectivity means that both power supplies excel, but the specific needs of your components may guide your choice.

Warranty and Reliability

The Lian Li SP750 V2 comes with a solid 10-year warranty, which signifies the manufacturer's confidence in the product's longevity and reliability. Similarly, the Seasonic Focus GX also offers a 10-year warranty, underscoring its durability. Both brands are known for producing reliable power supplies, and this extensive warranty period suggests that users can expect high-quality performance from either option. In terms of after-sales support, both models provide peace of mind with their long warranty periods.

Compatibility with New Technologies

The Lian Li SP750 V2 is ATX 3.1 certified and supports PCIe Gen 5.0, making it a future-proof choice for new builds. The Seasonic Focus GX matches this with its own ATX 3.1 and PCIe 5.1 compatibility, ensuring it can handle the latest graphics cards and power demands. Users planning to upgrade their systems frequently will appreciate the forward-thinking designs of both units. Thus, choosing either power supply will equip your system with the capability to support the latest technology.

Price Comparison

The Lian Li SP750 V2 is priced at $124.99, while the Seasonic Focus GX is available for $139.99. This makes the Lian Li about 10.7% cheaper than the Seasonic, which could be a decisive factor for budget-conscious consumers. If you're looking for a balance between performance and cost, the Lian Li offers a compelling value proposition without sacrificing essential features. However, the additional cost of the Seasonic may be justified for users who prioritize high efficiency and superior cooling.

Which should you buy?

Ultimately, the choice between the Lian Li SP750 V2 and the Seasonic Focus GX comes down to your specific needs. If you require a compact power supply that is budget-friendly and still offers solid features, the Lian Li SP750 V2 is an excellent option. However, if you prioritize efficiency, superior cooling, and are willing to invest a bit more, the Seasonic Focus GX may be the better choice. Both power supplies are reliable, modular, and equipped for the latest technology, ensuring either option will serve you well in your PC build.
