AsiaHorse Hydrus-24PIN PC PSU Extension, ATX 24PIN Motherboard Power Extension 90° Right Angle Design, 650W Power Supply, Perfect for PC Case Management & DIY Enthusiasts (White, 24Pin-ARGB) vs CORSAIR RM750e ATX 3.1 PCIe 5.1 Ready Fully Modular 750W Power Supply – 12V-2x6 Cable Included, Cybenetics Gold Efficiency, 105°C-Rated Capacitors, Modern Standby Mode – Black

Price Comparison: AsiaHorse Hydrus-24PIN vs Corsair RM750e

The AsiaHorse Hydrus-24PIN extension cable is about 65% cheaper than the Corsair RM750e power supply. At $31.99, the AsiaHorse product costs just over one-third of the Corsair’s $89.99 price tag. This massive difference reflects their fundamentally different roles: one is a simple cable extension, the other is a full power delivery system with advanced engineering and certification. The Corsair RM750e carries a premium due to its compliance with ATX 3.1 and PCIe 5.1 standards, while the AsiaHorse cable serves as a plug-and-play accessory for existing setups.

Functionality and Role in PC Builds

The AsiaHorse Hydrus-24PIN is not a power supply—it’s an extension cable designed to improve cable management by providing a 90° right-angle connection. It works with existing 24-pin motherboards and power supplies, offering flexibility without altering the core power delivery system. In contrast, the Corsair RM750e is a complete, fully modular power supply rated at 750W, engineered to deliver stable, high-efficiency power to modern components. It includes multiple connectors like 12V-2x6 and PCIe 8-pin cables, making it essential for building or upgrading a high-performance PC. The two products serve entirely different purposes: one enhances layout, the other powers the system.

Design and Build Quality

The AsiaHorse Hydrus-24PIN features a 30cm-long cable with a frosted, diamond-patterned finish and a 90° right-angle design that ensures clean, tight connections without bending. Its copper wire core with brass tin-plated terminals resists high voltage and temperature, supporting up to 900W per wire and 2500W across the entire setup. The cable also withstands over 40,000 bends thanks to durable PVC material. The Corsair RM750e, meanwhile, uses industrial-grade 105°C-rated capacitors and a 120mm rifle-bearing fan for long-term reliability and quiet operation. Its 140mm casing fits nearly any modern case, and the fully modular design allows users to connect only necessary cables—reducing clutter and improving airflow.

Power Efficiency and Certification

The Corsair RM750e is certified Cybenetics Gold efficiency, meaning it delivers high energy conversion rates with minimal waste heat. It also meets Intel’s ATX 3.1 standard, which supports PCIe 5.1 platforms and handles two transient power excursions from the GPU—critical for stability under load. The AsiaHorse Hydrus-24PIN does not claim any efficiency rating or certification; instead, it emphasizes low electrical resistance via its 18AWG copper core and brass terminals, reducing current loss and preventing issues like blue screens. While both aim for reliable power delivery, only the Corsair model has formal industry certification and performance benchmarks.

Compatibility and Use Cases

The AsiaHorse Hydrus-24PIN is compatible with most mainstream 24-pin motherboards and power supplies, functioning as a straightforward extension cable. It requires the original cable to be used alongside it and is ideal for DIY enthusiasts managing cable routing in tight cases. The Corsair RM750e is designed for modern builds requiring PCIe 5.1 support and ATX 3.1 compliance. It includes a native 12V-2x6 connector and multiple PCIe 8-pin cables, making it suitable for high-end GPUs and CPUs. Its fully modular design allows customization based on system needs, while the AsiaHorse cable offers no such flexibility—it’s a fixed-use accessory.

Noise and Thermal Performance

The Corsair RM750e features a 120mm rifle-bearing fan with a specially calculated fan curve that keeps noise levels low even under full load. This contributes to a quieter overall system, especially during sustained workloads. The AsiaHorse Hydrus-24PIN has no fan or thermal management system since it’s not a power supply—it simply extends an existing connection. Its performance depends entirely on the primary PSU’s cooling. Therefore, the Corsair unit actively manages heat and noise, while the AsiaHorse cable plays no role in thermal regulation.

Warranty and Longevity

The Corsair RM750e comes with a seven-year warranty, reflecting Corsair’s confidence in its build quality and component longevity. This extended coverage is backed by 105°C-rated capacitors and robust internal construction. The AsiaHorse Hydrus-24PIN does not list a warranty period in the provided data, suggesting it may come with limited or no formal protection. However, its durability claims—over 40,000 bend cycles and scratch-resistant materials—indicate strong physical resilience. Still, the absence of a stated warranty contrasts sharply with Corsair’s comprehensive support.

Which should you buy?

Choose the AsiaHorse Hydrus-24PIN if you need a low-cost, plug-and-play solution to improve cable routing in a tight case or enhance the look of your build with ARGB lighting. At $31.99, it’s about 65% cheaper than the Corsair RM750e and ideal for minor upgrades or DIY projects. Opt for the Corsair RM750e if you’re building or upgrading a high-performance PC requiring ATX 3.1 and PCIe 5.1 compatibility, full modularity, and gold-level efficiency. Priced at $89.99, it offers certified reliability, a seven-year warranty, and superior thermal and noise management—essential for demanding systems. The choice hinges on whether you need a cable fix or a complete power solution.
