Overview of AsiaHorse Hydrus-24PIN PC PSU Extension and ASRock PRO-650G Power Supply
The AsiaHorse Hydrus-24PIN PC PSU Extension and the ASRock PRO-650G Power Supply serve distinctly different purposes within the realm of PC hardware. The AsiaHorse Hydrus is an extension cable designed for cable management, while the ASRock PRO-650G is a full power supply unit. With the AsiaHorse priced at $31.99 and the ASRock at $49.99, the latter is about 56% more expensive.
Design and Build Quality
The AsiaHorse Hydrus features a 90° right-angle design that enhances cable management and minimizes bending, which is ideal for DIY enthusiasts. It boasts an integrated minimalist style, ensuring a clean and organized setup. In contrast, the ASRock PRO-650G features a flat cable design that also promotes improved airflow and easier cable management within the case. Both products emphasize durability, with the AsiaHorse capable of withstanding over 40,000 bends, while the ASRock utilizes high-quality Taiwanese capacitors for longevity.
Power Delivery Capability
The AsiaHorse Hydrus supports up to 900W power input on a single wire and a total of 2500W power supply capacity, making it highly efficient for its purpose as an extension cable. On the other hand, the ASRock PRO-650G delivers a stable 650W output with a robust 54.1A on the +12V rail, ensuring reliable power for mid-range systems. This makes the ASRock suitable for powering more demanding components like CPUs and graphics cards, unlike the AsiaHorse, which is not a power supply but rather a connector.
Efficiency Ratings
The ASRock PRO-650G holds an 80 PLUS Gold certification, boasting up to 90% energy efficiency. This certification signifies not only reduced power consumption but also lower heat output, which can lead to long-term savings on electricity bills. The AsiaHorse does not have an efficiency rating as it is not a power supply unit. Thus, if energy efficiency is a key consideration, the ASRock clearly holds an advantage.
Compatibility and Installation
The AsiaHorse Hydrus is designed to be compatible with most mainstream 24-pin power supply motherboards, functioning solely as an extension rather than a standalone power source. Its plug-and-play feature and easy bending make it user-friendly for installation. Meanwhile, the ASRock PRO-650G is ATX 3.1 ready, ensuring compatibility with the latest components and features a standard ATX form factor, fitting most PC cases. This makes the ASRock a versatile choice for a wide range of setups.
Cooling Solutions
The ASRock PRO-650G is equipped with a quiet 120mm fan, which balances performance and noise levels during operation. This is particularly beneficial for gamers and users who prefer a quieter environment. The AsiaHorse, lacking a cooling system as it is an extension cable, does not contribute to cooling but focuses on enhancing cable management. For users concerned about system cooling, the ASRock is the clear winner.
Warranty and Support
The ASRock PRO-650G comes with a 3-year warranty, providing peace of mind and reliable manufacturer support. This is a significant factor for users investing in critical components like power supplies, where reliability is paramount. The AsiaHorse does not mention a warranty period, which may be a consideration for buyers looking for long-term assurance. A longer warranty from the ASRock gives it an edge in terms of customer support and reliability.
Which should you buy?
Choosing between the AsiaHorse Hydrus-24PIN PC PSU Extension and the ASRock PRO-650G Power Supply ultimately depends on your specific needs. If you require a reliable power supply that offers excellent efficiency and stability for your system, the ASRock PRO-650G is the better choice at $49.99. However, if you're looking for an effective solution to enhance cable management without needing additional power, the AsiaHorse Hydrus at $31.99 is an excellent option. Consider your requirements carefully to make the right decision.
