Are all ATX power supplies the same?

Are all ATX power supplies the same?

All ATX12V power supplies maintain the same physical shape and size as the ATX form factor.

Is ATX power supply isolated?

The outputs of the ATX power supply are isolated from the mains. The outputs of the ATX power supply are not isolated from each-other. In other words, +5V and +12V output “share” the same ground. Multiple ground pins increase current carrying capacity.

How do I find out what power supply I have?

You can check the power supply on your PC by removing the side panel of its case. If you bought a prebuilt PC, you can also likely check the power supply in the computer’s manual or by contacting the manufacturer. Knowing your PC’s power supply can help you upgrade other parts of the computer, like your graphics card.

How do I know what wattage power supply I need?

The best power supply for your PC build is the one that provides the right amount of wattage to all components simultaneously. Manually calculating this requires that you multiply the total amps of all components by the total volts of all components. The result is the total watts that your PC build requires.

How do I choose a replacement power supply?

You should purchase an ATX power supply with the same or greater wattage than your previous power supply. As stated in (1i), the length dimension may vary beyond the typical 140MM, to be on the safe side we recommend making sure the length of the replacement unit is not greater than the length of the old unit.

How do you isolate power supply outputs?

The three commonly used methods for isolation are:

1. Physical power supply isolation using a media such as insulation, a dielectric medium, air gap or any other non-conductive path between conductor surfaces.
2. Transformers which provide isolation through magnetically coupling the primary side to the secondary winding.

How do I know if my power supply is isolated?

With a multimeter. Measure the resistance between various “output” pins and the “input” pins. A very high resistance (>1 meg ohm) or an open circuit means that it is isolated. A resistance of less than 10K ohms indicates that it is not isolated.
