SATA To 4 Pin Power Cable Adapter 3 Pack

The SATA to 4 Pin Power Cable Adapter converts a standard SATA power connection to a Molex LP4 interface, enabling legacy drives to receive power from modern power supplies. Each of the three cables provides a 7-inch length, making them suitable for internal routing in mid towers where space is a premium. The adapter is useful when adding older IDE drives or peripherals that still rely on a Molex power source.
SDTC Tech Dual SATA Power Splitter Cable

This 20 cm dual-SATA power splitter uses a 4-pin Molex LP4 male connector to feed two SATA devices from a single Molex source. The 18 AWG copper construction supports reliable low-voltage power delivery. It’s ideal for builds needing an economical, compact solution to power two drives from a single legacy connector, reducing cable clutter while preserving airflow.
Cable Matters 3-Pack Molex To SATA Power Cable

These 6-inch Molex to SATA power cables from Cable Matters provide a flexible, cost-effective solution for upgrading or repairing systems with Molex-powered power supplies. The three-pack offers spare or replacement cables, useful for DIY builders and IT technicians handling multiple drives, optical devices, or expansion drives within desktop PCs.
ATX 4PIN To Dual SATA Power Extension Cable

This ELFJMZP Store extension cable converts an ATX 4-pin motherboard power connector into two SATA power ports. It’s designed to maximize available power rails, powering two drives or devices from a single connection. The right-angle design helps with space-saving cable routing in tighter chassis environments and supports a tidy interior layout for improved airflow and maintenance.
Cable Matters 3-Pack Dual SATA Power Y-Cable

The dual-SATA Y-Cable from Cable Matters offers two SATA drives powered from a single LP4 Molex connector. As a cost-effective 3-pack option, it provides flexibility for upgrading or repairing internal storage configurations, especially when the power supply lacks multiple dedicated SATA power connectors. It is well-suited for standard desktop builds that require additional drive connections without upgrading the PSU.
Buying Guide
- Power compatibility: Ensure the adapter provides the correct pin configuration for your devices—Molex LP4 to SATA or SATA to Molex. Check the number of SATA ports powered from a single LP4 and the total current rating for your drives.
- Cable length: Shorter cables reduce clutter, but longer options offer flexible routing in larger cases. Consider 6-inch to 20 cm lengths for most mid-tower builds, or longer if the layout demands it.
- Build quality and conductor gauge: Look for 18 AWG or better for reliable power delivery, especially when powering multiple drives from a single source.
- Space and airflow: Right-angle designs and compact connectors can improve airflow by reducing cable interference near fans and heat sinks.
- Versatility vs. specialization: If you frequently swap drives, a 3-pack of cables provides handy spares. For minimal setups, a single adapter may suffice.
- Safety and compatibility: Prioritize adapters from reputable brands and verify that the combined load from connected drives does not exceed your PSU’s available rails.
- Future-proofing: If you plan to add more drives, consider dual-SATA splitters or Y-cables that maximize the number of devices powered from a single Molex connection.
When selecting a 4 pin power to SATA solution, balance the need for additional connectors with cable management, space, and long-term reliability. The options above cover common scenarios—from single-drive expansion to dual-drive configurations—across a range of lengths and packing configurations.
