Price Comparison
The Redragon RGPS-850W is priced at C$154.99, while the FKBAightccy for PS5 Power Supply is significantly more affordable at C$69.99. This substantial difference of C$85 highlights the varying target markets for these two products. The Redragon model is designed for high-performance gaming PCs, providing robust power and efficiency, whereas the FKBAightccy is an internal replacement power supply specifically for the PlayStation 5. If budget is your primary concern and you are looking to replace a PS5 power supply, FKBAightccy offers a compelling option at a lower price point.
Target Audience
The Redragon RGPS-850W caters to gamers and PC builders who require a premium power supply for high-end components. It is suitable for those using advanced graphics cards like the NVIDIA RTX 40/50 series, making it ideal for serious gaming setups. On the other hand, the FKBAightccy is tailored for PlayStation 5 users needing a replacement power source for their console models, such as CFI-1015A/B and CFI-1115A/B. Each product is designed with a specific user base in mind, leading to differences in features and pricing.
Performance Specifications
Redragon RGPS-850W boasts an 80 Plus Gold certification, ensuring high energy efficiency and lower heat generation at a total power output of 850 watts. This feature is particularly beneficial for gaming rigs that demand stable power delivery under heavy loads. In contrast, the FKBAightccy provides a power output of +12V at 31A, which is adequate for the PS5. While the Redragon offers a significantly higher wattage suitable for multiple high-performance components, the FKBAightccy meets the requirements necessary for the console's operation.
Build Quality and Reliability
The Redragon RGPS-850W is constructed with 100% Japanese capacitors, enhancing reliability and durability, which is crucial for maintaining performance over time. This power supply is built to withstand the demands of high-performance gaming and heavy usage. Conversely, the FKBAightccy, made of high-quality ABS material, is marketed as lightweight and durable, but it does not specify the use of premium components like Japanese capacitors. Thus, while both products claim durability, the Redragon RGPS-850W likely offers a higher level of build quality suited for extensive use.
Cooling and Noise Levels
The Redragon RGPS-850W features a Zero RPM Mode fan that operates silently until temperatures exceed 60℃, ensuring a quiet environment during low load periods. This aspect is particularly appealing to gamers looking for a silent operation while gaming or during idle times. In contrast, the FKBAightccy does not mention any cooling features, which may imply a standard fan operation without specific enhancements for noise control. Therefore, the Redragon RGPS-850W is better suited for those who prioritize a quiet computing experience.
Aesthetics and Design
The Redragon RGPS-850W offers up to 9 RGB modes with 26 selected colours, allowing users to customize the aesthetics of their gaming rig while maintaining low power consumption. This feature not only enhances the visual appeal of a gaming setup but also aligns with modern trends in PC building. On the other hand, the FKBAightccy focuses on functionality rather than aesthetic appeal, providing a straightforward design intended for internal use in the PS5 console. For users who value visual customization, the Redragon RGPS-850W is the clear winner.
Installation and Compatibility
Installing the FKBAightccy for PS5 is designed to be convenient, coming with a new power cable and tools for installation, making it user-friendly for those less experienced with hardware. The compatibility with various PS5 models is also clearly outlined, ensuring users select the correct power supply. In contrast, the Redragon RGPS-850W is compatible with a wider range of PC components due to its ATX 3.1 and PCIe 5.1 readiness, allowing it to support high-performance GPUs and dual CPU setups. While the FKBAightccy offers ease of installation for PS5 users, the Redragon RGPS-850W provides broader compatibility for gaming PC builders.
Which should you buy?
If you are a serious gamer looking to build or upgrade your gaming PC, the Redragon RGPS-850W 80+ Gold power supply is the superior choice due to its high wattage, premium build quality, energy efficiency, and customizable RGB features. However, if you simply need an affordable replacement for your PS5 power supply, the FKBAightccy is a practical option that meets the necessary specifications for the console without breaking the bank. Ultimately, your decision should hinge on whether you require a high-performance power supply for a PC or a straightforward replacement for a gaming console.
