Overview of the Products
The AsiaHorse 16AWG PSU Extension Cable Kit Black and the JUSTOP Black 700W Power Supply Unit ATX PSU With 120MM Quiet Fan offer distinct functionalities for PC builders. The AsiaHorse kit, priced at £29.99, focuses on enhancing power delivery stability through premium cabling, while the JUSTOP PSU, available for £29.95, serves as a reliable power source for various components. Both products cater to different needs within the PC building community, making them interesting options for comparison.
Build Quality and Materials
The AsiaHorse extension cable kit stands out with its premium 16AWG pure copper core, designed for lower resistance and superior heat resistance. This ensures stable voltage transmission, crucial for preventing system crashes during high loads. In contrast, the JUSTOP PSU employs standard construction but boasts safety features, including over voltage and short circuit protection. The JUSTOP's design is aimed at delivering safe and stable power with a robust 12CM quiet cooling fan, which helps maintain optimal operating temperatures. The choice here hinges on whether you prioritise the quality of internal connections or the reliability of the power supply itself.
Compatibility
Compatibility is a critical factor for both products. The AsiaHorse kit is designed with wide GPU compatibility in mind, featuring two PCI-E 6+2 pin cables tailored for high-end graphics cards, including the NVIDIA GeForce RTX and AMD Radeon series. This ensures that users can confidently extend their power supply connections without concern for compatibility issues. On the other hand, the JUSTOP PSU is compliant with Intel ATX 12V v.2.3 and EPS 12V v.2.92 standards, making it suitable for most motherboards and CPUs. While both products promise compatibility, the AsiaHorse kit excels in supporting high-performance graphics setups.
Performance Under Load
When it comes to performance under load, the AsiaHorse kit is engineered to prevent unstable power delivery, thus reducing the risk of crashes and frame drops during intensive tasks. This is particularly beneficial for gamers and content creators who push their systems to the limits. The JUSTOP PSU, with its 700W output and a 70% efficiency rating, provides a solid power foundation for mid-range builds. It features a single 8-pin (4+4) rail for stability, ensuring a dependable power output. Users looking for solid performance in demanding conditions will find the AsiaHorse cable kit to be a more specialised solution.
Aesthetics and Design
In terms of aesthetics, the AsiaHorse kit offers ultra-soft nylon braiding that not only enhances the look of your PC build but also allows for easy routing in tight spaces. With cable combs included, users can achieve a clean, organised appearance that elevates the overall build quality. Conversely, the JUSTOP PSU's design is more utilitarian, favouring functionality over style. While it does include a cooling fan that operates quietly, users seeking to showcase their build may feel that the JUSTOP lacks the visual appeal of the AsiaHorse kit.
User Experience and Installation
The AsiaHorse extension kit is designed for easy installation, allowing users to hide unsightly factory PSU cables behind the motherboard tray. This not only improves airflow but also contributes to a professional-looking build. The kit's soft materials make it easier to work with in confined spaces. The JUSTOP PSU also promotes ease of use with its comprehensive connector options, including a variety of SATA and Molex connections. However, the installation may be less aesthetically pleasing when compared to the cable kit. Ultimately, those who prioritise a clean look may favour the AsiaHorse kit for its superior routing capabilities.
Safety Features
Safety is paramount in PC builds, and both products incorporate important protective features. The AsiaHorse kit is built for longevity and safety, utilising high-grade materials to prevent hazards during operation. The JUSTOP PSU, meanwhile, is equipped with several safety mechanisms including over voltage and thermal overload protection, ensuring that your components are safeguarded against potential electrical issues. While both products offer essential safety features, the JUSTOP's comprehensive protections make it a reassuring choice for those concerned about power supply stability.
Price and Value
Both products are priced competitively, with the AsiaHorse kit at £29.99 and the JUSTOP PSU at £29.95. Given their respective features, the value proposition varies significantly. The AsiaHorse kit offers the advantage of enhanced stability and aesthetics for power delivery, which can justify its slightly higher price for users focused on performance and visual appeal. The JUSTOP PSU, while slightly cheaper, provides a reliable power source with essential safety features, making it an excellent option for budget-conscious builders. The decision ultimately depends on whether users value aesthetics and cable performance over a straightforward power supply solution.
Which should you buy?
Choosing between the AsiaHorse 16AWG PSU Extension Cable Kit Black and the JUSTOP Black 700W Power Supply Unit ATX PSU With 120MM Quiet Fan depends largely on your specific needs. If you're looking for enhanced stability and aesthetics in your PC build, the AsiaHorse kit is the clear choice. However, if you require a reliable power source with solid safety features and a lower price point, the JUSTOP PSU may be the better option. Each product serves its purpose well, so consider what aspects matter most to you in your PC building journey.
