SATAGear

SATAGear SS-08MPS 4-Pin Molex to 15-Pin SATA Power Cable

SKU CH-4KM2-J5RDX

Converts a 4-pin Molex connector to a 15-pin SATA power plug for powering serial drives

  • Converts 4-pin Molex to SATA 15-pin power
  • Powers SATA drives from legacy PSU connectors
  • 8-inch length fits tight drive bays
  • IDC termination ensures secure pin contact
  • 15-pin male connector matches SATA power standard

Power Conversion

This SATAGear cable converts a four-pin Molex connector from the power supply into a 15-pin SATA power connector. It is intended for builders who need to supply power to SATA hard drives or SSDs when the PSU lacks native SATA leads. The adapter provides a direct electrical path without active components.

Passive Operation

The cable contains no fan, controller or voltage regulator, so it adds no noise and draws no power of its own. Heat is limited to the resistance of the conductors and the contact surfaces. Reliability depends on the quality of the Molex and SATA sockets on the host hardware.

Sustained Delivery

Under continuous load the adapter passes whatever current the drive requires up to the rating of the connectors and wire gauge. It does not throttle, shut down or change behaviour over time. Builders who need to power more than one drive from a single Molex lead should use a splitter or additional cables.

Questions about this item

How do I connect the 4-pin Molex end to my power supply and the 15-pin SATA end to my drive?

Plug the 4-pin Molex connector firmly into a free Molex socket on the PSU until it clicks, then push the 15-pin SATA connector straight onto the drive's power port; the step people miss is seating both ends fully so no pins stay partially exposed.

Will the connectors or cable degrade and need replacing after a few years of use?

The IDC crimp joints and Molex pins are rated for the drive's lifetime; only physical damage from repeated unplugging or cable stress would require a new adapter.

What stops me from running multiple high-draw drives on this single adapter for hours?

The 4-pin Molex source limits total current to its per-pin rating, so sustained heavy loads on one adapter will hit that ceiling before the short cable run does.
