Price Comparison
The Lian Li SP850 V2 Gold is priced at C$194.23, while the FKBAightccy for PlayStation 5 power supply is significantly cheaper at C$67.99. The price difference of C$126.24 reflects the intended use and specifications of each product. The Lian Li model is designed for high-performance PC builds, offering advanced features like full modularity and ATX 3.1 certification, which justify its higher cost. In contrast, the FKBAightccy model serves as a replacement power supply specifically for the PlayStation 5, appealing to a more niche market that prioritises cost over extensive features.
Design and Build Quality
The Lian Li SP850 V2 Gold is built to fit the official SFX size specification of ≤63.5mm, featuring a robust design that includes high-quality Japanese electrolytic capacitors for stable power delivery. It also includes a premium 92mm FDB fan for efficient cooling, ensuring longevity and quieter operation. On the other hand, the FKBAightccy for PlayStation 5 is made from high-quality ABS material, focusing on durability and lightweight design. However, it lacks the same level of advanced engineering found in the Lian Li model, as it is primarily a straightforward replacement part rather than a high-performance component.
Features and Performance
The Lian Li SP850 V2 Gold boasts several standout features, including full modular cabling, ATX 3.1 certification, and a native 12V-2x6 connector, making it highly versatile for modern gaming rigs and ensuring compatibility with PCIe Gen 5.0 graphics cards. It also supports high-performance peripherals with an upgraded 5VSB rail that increases capacity from 2.5A to 3A. In contrast, the FKBAightccy power supply is specifically designed for the PS5, with output voltage of +12V and a maximum current of 31A. While it addresses common power issues for the console, it does not offer the same level of performance or versatility as the Lian Li unit.
Compatibility
The Lian Li SP850 V2 Gold is compatible with a wide range of PC components, adhering to the latest ATX 3.1 standards, making it suitable for high-performance gaming and workstation builds. Its full modularity allows users to connect only the cables they need, reducing clutter and enhancing airflow within the case. Conversely, the FKBAightccy power supply is explicitly designed for the PlayStation 5, compatible with models that use the ADP-400FR / PA-1401-JT3 power supply. This limited compatibility means it is not suitable for users looking to power anything beyond a PlayStation 5 console.
Installation Process
The Lian Li SP850 V2 Gold is designed for PC enthusiasts who may appreciate the modular installation process, allowing for a custom configuration tailored to their system's needs. The ease of installation is enhanced by the included cables, which are colour-coded for clarity. In comparison, the FKBAightccy power supply comes with a new power cable and installation tools, making it accessible for users who may not have prior technical experience. However, it is important to note that professional assistance is recommended for those unfamiliar with installing power supplies in gaming consoles, which may complicate the process for some users.
Warranty and Support
The Lian Li SP850 V2 Gold offers a substantial 10-year hardware protection warranty, reflecting the brand's confidence in its durability and performance. This long warranty period is a strong selling point for users investing in high-end components, as it assures them of support should any issues arise. In contrast, the FKBAightccy power supply does not specify a warranty period, which could be a concern for consumers prioritising long-term reliability. The lack of detailed warranty information may deter potential buyers who want assurance regarding the longevity of their purchase.
Target Audience
The Lian Li SP850 V2 Gold targets PC builders and gamers looking for a high-quality, reliable power supply that can support the latest hardware and provide excellent thermal performance. Its advanced features and price point are ideal for enthusiasts who require a robust power solution. On the other hand, the FKBAightccy power supply is aimed at PlayStation 5 users needing a cost-effective replacement for a malfunctioning unit. Its lower price and straightforward functionality make it suitable for casual gamers who may not require advanced features.
Which should you buy?
Ultimately, the decision between the Lian Li SP850 V2 Gold and the FKBAightccy for PlayStation 5 power supply hinges on your specific needs. If you are a PC enthusiast seeking a powerful, versatile, and durable power supply that meets modern standards, the Lian Li SP850 V2 Gold is the clear choice, albeit at a higher price of C$194.23. However, if you require a budget-friendly replacement specifically for a PlayStation 5 and are looking to resolve power issues without needing extensive features, the FKBAightccy at C$67.99 is a practical option.
