Question

A technician is adding a fourth SATA hard drive to a workstation, but the modular power supply only provides three SATA power leads and all are already in use. The motherboard still has an open SATA data port. What is the BEST way to power the new drive without replacing the power supply?

Accepted Answer

Use a Molex-to-SATA power adapter connected to an available 4-pin Molex lead

Answer

Split the existing SATA data cable to feed both power and data to the new drive

Answer

Connect the drive using only the SATA data cable, since it also supplies power

Answer

Attach the drive to a spare 8-pin PCIe/CPU power connector from the PSU
