![]() 48V 2A DC Power Supply 6.5 x 4.4mm ADS-110DL-52-1 480096G Power Supply that provides up to 2A of power at 48V DC. Pin 14 goes from 0 to 3.7 when PSU switch is turned on. Female 4 Pin Molex Crimp Connector with Plastic Housing and 4 Female Metal Crimps. Pin 9 (standby) supply 5V even when PSU is turned off. In addition, some PSU violate color coding of wires. In several power supply units pin-12 may be Brown (not Blue), pin-18 may be Blue (not White), and pin-8 may be White (not Gray). PS_ON activated by pressing and releasing the power button while the power supply is in standby mode. Shorting the pin 14 (/PS_ON) to GND (COM) causes power supply to switch ON. 5 VDC (2002 v1.2 made optional, 2004 v2.01 removed from specification) Short this pin to GND to switch power supply ON, disconnect from GND to switch OFF. StarTechs 4-Pin Molex to SATA Power Cable Adapter features one 4-pin Molex (LP4) male connector and one female SATA power connector, allowing you to power a Serial ATA hard drive from a conventional LP4 connection, eliminating the need to upgrade the computer power supply for compatibility with the SATA hard drive. +12 VDC (may sometimes have a colored stripe to indicate which rail it's on) +5 VDC Standby Voltage (max 10mA) 500mA or more typical ![]() Power Ok is a status signal generated by the power supply to notify the computer that the DC operating voltages are within the ranges required for proper computer operation (+5 VDC when power is Ok when PSU is turned ON) It was used for floppy drives and hard disks. And graphics card by design doesnt use molex connector for external. The four pin peripheral power cable dates back to the original PC. Molex connector in PC power supply doesnt have 6 or 8 pins. What power supplies have a 4 pin connector 4 pin peripheral power cable. Current version of ATX12V 2.x power supply provides two connectors for the motherboard: a 4-pin auxiliary connector providing additional power to the CPU, and a main 24-pin ATX 2 power supply connector, an extension of the original 20-pin version. The ATX 4-pin power supply connector is a standard motherboard power connector used to provide +12 VDC to the processor voltage regulator. Originally the motherboard was powered by one 20-pin connector. A −5 V output was originally required because it was supplied on the ISA bus, but it became obsolete with the removal of the ISA bus in modern PCs and has been removed in later versions of the ATX standard. Low-power −12 V (☑.2 V) and 5 VSB (standby) (☐.25 V) supplies are also required. The ATX specification requires the power supply to produce three main outputs, +3.3 V (☐.165 V), +5 V (☐.25 V) and +12 V (☐.60 V). Nowdays this standard is obsolete and superseeded by ATX 2.2 (24 pin). In addition to the old AT standard, ATX 2.0 has one extra voltage line available (+3.3V), a connector chain-lined to the single 20-pin and a power-on wire that allows Software to turn off the PSU. ATX specification includes not only Power Supply Unit, but also interface to case and motherboard.
