A 22 cm cable with a large 4-pin male plug splitting to three SATA female connectors, yellow black red PVC wires

Ruth's sister

Ruth's sister IDE 4Pin Male to 3 SATA Female Splitter Cable 22cm

SKU CH-RKGA-AA1TG

Converts a single 4-pin power connector into three SATA ports using 22 cm of 1007 22AWG tinned-copper cable rated to 80 °C

  • Convert one power-supply 4-pin connector into three SATA power ports
  • 22 cm cable keeps internal routing tidy and compact
  • PVC insulation rated to 80 °C for safe operation
  • Tinned-copper conductors (17 × 0.12 mm) ensure reliable current delivery
  • Lightweight 19 g design adds minimal mass to the build

Power-splitter cable for legacy PSUs

This Ruth's sister adapter converts a single large 4-pin Molex connector from the power supply into three SATA power sockets. It lets builders attach up to three SATA drives or peripherals without needing native SATA leads from the PSU. The 22 cm length keeps cable routing tidy inside compact cases. No active electronics are involved; the splitter simply distributes the existing 12 V and 5 V rails.

Wiring and build integration

The cable uses 1007 22 AWG tinned-copper conductors (17 strands of 0.12 mm) with PVC insulation rated to 80 °C and an outer diameter of 1.6 mm. One end carries a large 4-pin female Molex plug; the three branches terminate in standard SATA female power connectors. Total weight is 19 grams, adding negligible mass to the harness. Ensure the host PSU Molex circuit can supply the combined current draw of all attached drives.

Capacity and practical limits

Three SATA devices share the amperage available on the single Molex source, so high-spin-up mechanical drives may exceed the connector's rating if started simultaneously. The 22 cm reach suits drives mounted near each other; wider spacing will require additional extension cables. Builders needing more than three SATA power drops or separate 12 V rails should look for a PSU with native SATA outputs or a multi-rail splitter.

Questions about this item

How many SATA drives can one 4-pin Molex connector power with this 22 cm splitter?

The cable splits a single large 4-pin power supply connector into three SATA female ports, so up to three SATA drives can be powered from one Molex output.

Does the PVC-insulated 22 AWG wire run warm when all three SATA ports are loaded continuously?

The 17-strand tinned copper conductors (0.12 mm each) are rated to 80 °C, so the cable stays within its thermal limit under normal sustained loads.

What power supply connector is required at the other end of this 22 cm cable?

The splitter expects a standard large 4-pin Molex (D-shaped) male connector from the power supply to feed the three SATA female ends.
