SATA Data Power Combo Cable - XH2.54 4PIN to 7+15P 2-in-1 Adapter for HDD SSD Optical Drive, 6Gbps High-Speed SATA III Cable for PC Motherboard Power Supply

Product Summary

This SATA data+power combo cable is a must-have for PC builders and upgraders: it eliminates the hassle of separate data/power wires, solves old PSU SATA power shortages, and supports high-speed 6Gbps data transfer for SATA III devices. Its durable construction and universal compatibility (works with all SATA devices and most motherboards/PSUs) make it a reliable choice for organizing internal PC cables or expanding storage.

Important Notes:

1. Voltage and Power Compatibility

Suitable only for standard 12V/5V PC power supplies (default output voltage for XH2.54 mini 4-pin connectors). Connecting to industrial-grade high-voltage power sources is strictly prohibited to prevent device damage.

Maximum supported power per cable 100W. Connecting multiple 3.5-inch HDDs is not recommended (each 3.5-inch HDD consumes approximately 10-15W; connect 1-2 drives per cable) to prevent overloading and overheating.

2. Installation Guidelines

Before installation, ensure the PC power supply is switched off and the power cable is disconnected to prevent live connections causing short circuits to the motherboard, hard drive, or power connectors.

When inserting connectors, align them with the latch direction (SATA connectors feature a foolproof design). Avoid forceful insertion or removal to prevent damage to connector pins.

When organising chassis cables, avoid excessive bending (minimum bend radius 2cm) and keep them clear of rotating components such as CPU fans and graphics card fans to prevent entanglement or abrasion.

3. Compatibility Verification

Confirm your power supply features an XH2.54 standard small 4-pin connector (distinct from the larger 4-pin variant) to prevent incompatibility issues.

Compatible only with SATA interface devices (2.5-inch SSDs, 3.5-inch HDDs, SATA optical drives). Not compatible with M.2 interfaces, NVMe protocol devices, or IDE interface devices.

4. Routine Use and Maintenance

During prolonged use, periodically inspect cables for damage: cease use immediately and replace if insulation is compromised or connectors show oxidation (rust/darkening) to prevent short-circuit risks.

Keep cables away from high-temperature components (e.g., CPU coolers, graphics cards) and ensure adequate case ventilation to prevent accelerated cable ageing.

5. After-Sales and Warranty Information

If a connected device fails to respond, first verify that the interface is securely seated and that power is being supplied correctly. Alternatively, test compatibility by connecting another SATA device.

This product warranty covers the cables themselves only. We accept no liability for damage resulting from improper installation, abnormal voltage, or inherent device faults.
