AsiaHorse 16AWG PSU Extension Cable Kit Black vs Sirlyr PSU Cable Extension Kit

Price Comparison

AsiaHorse is significantly more expensive than Sirlyr, priced at £29.99 compared to Sirlyr’s £17.94 — a difference of £12.05, or about 40% higher. While AsiaHorse maintains a consistent average price of £29.99 over the past 30 and 90 days, Sirlyr has fluctuated slightly, averaging £21.68 over 30 days and £22.73 over 90 days, suggesting greater pricing volatility. Despite this, Sirlyr offers a clear value advantage with its lower current price and strong bestseller rank of 25, indicating solid consumer demand. The cost gap makes Sirlyr the more budget-conscious choice without sacrificing core functionality.

Cable Gauge and Core Quality

Both cables use a 16AWG thickened copper core, ensuring equivalent electrical performance and heat resistance. This shared specification means both products are engineered for stable voltage delivery under high loads, reducing risks of system crashes or frame drops. AsiaHorse specifies UL1015 16AWG tinned copper wire, while Sirlyr describes an alloy copper core meeting high PC power supply standards. Though materials differ slightly in description, the gauge remains identical — a critical factor for power integrity. Neither product uses a thinner 18AWG standard, which could compromise stability under heavy workloads.

Cable Sleeving and Aesthetics

AsiaHorse features soft nylon braiding in black, offering a sleek, flexible finish ideal for custom builds where colour coordination matters. Its sleeving is described as shrink-free and extremely soft, enabling easy routing in tight spaces. Sirlyr, by contrast, delivers an all-white design with glossy white nylon braided cables, specifically tailored for all-white PC builds. This aesthetic focus sets it apart from AsiaHorse’s black option, catering to users prioritising visual harmony. Both brands include cable combs, but Sirlyr’s combs are pre-installed and come in matching white, enhancing the cohesive look of a clean build.

Cable Combs and Cable Management

Sirlyr includes a more extensive set of cable combs: three pre-installed transparent combs per cable plus an extra set of 24-pin x3 and 8-pin x9 combs, providing greater flexibility for customisation. AsiaHorse also provides cable combs but does not specify the exact quantity beyond mentioning their inclusion. The pre-installation on Sirlyr’s cables streamlines setup, reducing user effort during installation. Both kits aim to keep cables parallel and organised, improving airflow and internal neatness, but Sirlyr’s larger complement of extras gives it a practical edge in long-term management and adaptability across different builds.

Connector Specifications and Compatibility

Both kits include one 24-pin ATX, one 4+4 pin EPS, and two 6+2 pin PCI-E connectors — identical configurations designed to extend factory PSU cables by 30cm. This ensures universal compatibility with major brands like Corsair, EVGA, Seasonic, and others. Sirlyr explicitly mentions gold-plated terminals, which reduce resistance and minimise heating, enhancing signal transmission. AsiaHorse does not mention plating but highlights pure copper core for stability. Both support high-end GPUs such as RTX 3060/4060/4070 and AMD RX 6600/6700 XT, making them suitable for mainstream gaming rigs and high-performance systems.

Build Quality and Longevity

AsiaHorse claims rigorous testing standards and long-term durability, backed by responsive customer support within 24 hours. It emphasises safety and longevity through high-grade materials and stable voltage transmission. Sirlyr similarly asserts superior stability for power supplies ranging from 800W to 1600W, reinforcing reliability under high load. Both brands highlight robust construction, though AsiaHorse places more emphasis on customer service and safety assurance. Neither product includes warranty details, but Sirlyr’s focus on gold-plated pins and thickened cores suggests premium engineering, while AsiaHorse underscores consistency in performance and material quality.

Which should you buy?

Choose Sirlyr if you want a lower price (£17.94 vs £29.99), an all-white aesthetic for themed builds, and a larger set of cable combs including extras for customisation. Its gold-plated connectors and 16AWG core ensure top-tier performance, while its bestseller rank of 25 reflects strong market trust. However, if you prefer black sleeving for darker builds and prioritise brand-specific support with a consistently priced product, AsiaHorse offers reliable stability and a clean, professional look. Ultimately, Sirlyr delivers better value and versatility, making it the smarter pick for most users seeking performance, aesthetics, and savings.
