PC POWER SUPPLY CONNECTION DIAGRAM
Convert ATX Power Supply to Bench Supply
Convert an old computer ATX power supply to a highly-capable workbench power supply. One thing to look out for is that the meter uses a shunt in the ground connection to measure current. Here is the wiring diagram.
Power Supply Connectors Guide - Types of PC Power Connectors
And while a power supply looks like a big mess of cables to the untrained eye, there's only a few types of PC power connectors that you'll need to know when connecting a power supply. Since SATA and Molex power connectors do not have clips, be sure to insert them firmly so that they won't come loose or get disconnected. 1.
All about the various PC power supply cables and connectors
The original PC debuted in 1981 and used two cables to connect the PSU (power supply) to the motherboard. The two cables plug side by side into the motherboard connectors. Sometimes they are keyed so they only plug in one way and sometimes they aren't.
Power Supply Connectors and Pinouts - PC Modding, Case
That way, your power supply only needs to have one 6+2 cable to be compatible with both 6 pin and 8 pin PCI Express connectors. 4 Pin Peripheral Power Cable Connector. The four pin peripheral power cable dates back to the original PC. It was used for floppy drives and hard disks.
Identify the Connectors of the Power Supply - CCM
Identifying the Power Supply Connectors in a PC The reference on the side, unique to each manufacturer, will allow you to identify the model. For example, the reference SP-ATX-650WTN-PFC refers to the brand (Spire, or SP), the standard for the power supply (ATX), the output (in watts) of the power supply (650WTN), and the Power Factor Correction (active or passive):
Molex connector - Wikipedia
Molex connector is the vernacular term for a two-piece pin and socket interconnection. Pioneered by Molex Connector Company, the two-piece design became an early electronic standard. Molex developed and patented the first examples of this connector style in the late 1950s and early 1960s. First used in home appliances, other industries soon began designing it into their products from
Computer Power Supply- Diagram and Operation
The above diagram shows a so-called forward converter with active reset. Half-bridge is also often used in the PC designs. See examples of schematics based on half-bridge: 250W and 300W. The main switch Q2 periodically applies voltage Vdc to the primary of power transformer T1.
Circuit Diagram Of Smps Power Supply
It is somewhat similar to the above explained DC to DC converter, but instead of direct DC power supply, here AC input is used. So, the combination of the rectifier & filter, shown in the block diagram is used to convert the AC into DC & switching is done by using a power ‘MOSFET’ amplifier with which very high gain can be obtained.
