There are a variety of integrated circuits you’ll find running the show whose data sheets will often give you an entire ATX power supply schematic, but since their circuitries will often be very ...

Upon restoration of ac power, an ATX power supply delivers a standby voltage of 5V dc at a maximum of 10 mA via Pin 9 of its power connector . With standby power available, low-power CMOS timer TLC555 ...

To make everything work, a load resistor on the 5V circuit makes the power supply think it’s hooked up to a motherboard. It’s all wrapped up in a neat slant-sided 3D-printed case that fits ...

Figure 1 shows a block diagram for a power supply like TDK-Lambda’s CUS350M, which features a main output, an auxiliary output (typically used for driving fans) and a standby voltage.A remote on/off ...
