The venerable ATX standard was developed in 1995 by Intel, as an attempt to standardize what had until then been a PC ecosystem formed around the IBM AT PC’s legacy. The preceding AT form factor was ...

Standard ATX power supplies aren't designed to turn on unless they are properly connected to a motherboard. This helps to ensure that they can't power up and damage computer components if the plug isn ...

If your computer is behaving strangely or randomly crashing, it can be hard to nail down the culprit. And as much as you don't want to believe it's the problem, testing your power supply should be ...

Switched-mode power supplies are found in electronics all around us. They provide the DC voltages that power our computers, cell phones, chargers, appliances, and myriad other electronic devices.

Today, 80% of all input/output (I/O) devices in automation applications are supplied with 24VDC power. The second most popular voltage is 120VAC, which is used on 15% of all I/Os. Over the past decade ...

The power supply on a computer transforms the alternating current from the wall outlet into a direct current flow that the computer's components can use. Testing the DC voltage output of the power ...

The circuit of power supply for PC works with a mains voltage of 230VAC to produce an output of 13.8V at 5A due to rectification. This project came upon the modification of a PC switch mode power ...

Economy of scale is a wonderful thing, take the switch-mode power supply as an example. Before the rise of the PC, a decent multi-voltage, high current power supply would be pretty expensive. But PCs ...

The flyback design is a switched-mode power supply (SMPS) that’s been used for 70+ years and still going strong. This supply—also called a power converter—has two distinct operating phases, with power ...

The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.
