A technician is servicing an older desktop computer that contains a PATA hard drive and a CD-ROM drive. Which connector from the power supply unit (PSU) is typically used to power these types of drives?
USB-C
DB-9
USB 3.0
Molex
The 4-pin Molex connector was the standard for providing power to internal PATA (IDE) hard drives and optical drives. It delivers both +5V and +12V DC. While newer storage devices use the 15-pin SATA power connector, Molex connectors are still found on older power supplies and are sometimes used for other devices like case fans. USB-C and USB 3.0 are used for external peripherals, and the DB-9 connector is a legacy serial port used for data transfer, not internal power.
