In computing, a power supply unit (PSU) or power supply is a component that supplies electrical power to a computer system. The PSU converts standard AC power to the DC power required by the computer’s internal components.
A good quality power supply is important for a reliable system. A PSU can last for years if it is properly selected and installed. However, if it is not of good quality, it can lead to problems such as failed components, data loss, or even a system crash.
There are a number of factors to consider when selecting a PSU. The most important are the wattage and the voltage. The wattage indicates the total power that the PSU can provide, and the voltage indicates the amount of power that is available at each voltage rail. Other factors to consider include the number of SATA and PCIe connectors, the length of the cables, and the type of cooling.
When installing a PSU, it is important to make sure that it is properly seated in the case and that all of the cables are properly connected. The most common problem with a PSU is a faulty cable.
A PSU is usually a self-contained unit that is not usually serviceable by the end user. However, in some cases it is possible to replace the fan or the capacitors.
There are a number of different types of PSUs available on the market, including ATX, SFX, and TFX. The most common type is the ATX PSU.
ATX power supplies are the most common type of power supply available on the market. They are typically large and rectangular, and they have a number of connectors on the back. ATX power supplies are used in desktop and tower cases.
SFX power supplies are smaller than ATX power supplies, and they are typically used in small form factor cases. They have a number of connectors on the back, including a 6-pin PCIe connector.
TFX power supplies are even smaller than SFX power supplies, and they are typically used in ultra-slim form factor cases. They have a number of connectors on the back, including a 6-pin PCIe connector and a 4-pin Molex connector.
Most PSUs are designed to work with a specific type of case. It is important to make sure that the PSU is the right size and type for the case that is being used.
There are a number of different wattages available for PSUs. The wattage that is needed depends on the components that are being used in the system. A good rule of thumb is to choose a PSU that is equal to or greater than the wattage of the components.
There are three main voltage rails that are used in computers: 3.3 volts, 5 volts, and 12 volts. The voltage that is needed depends on the components that are being used. A good rule of thumb is to choose a PSU that provides the same or greater voltage than the components require.
Most PSUs provide a number of different connectors for different types of devices. The most common connectors are SATA and PCIe. SATA connectors are used to connect hard drives, optical drives, and solid state drives. PCIe connectors are used to connect video cards, sound cards, and other expansion cards.
The length of the cables is also important. The cables should be long enough to reach the components that need to be connected. However, they should not be so long that they are difficult to manage.
The type of cooling is also important. Some PSUs come with a built-in fan, while others do not. It is important to choose a PSU that has a fan if the case does

How does a PSU work?
A power supply unit (PSU) is the component of a computer that converts mains AC to low-voltage DC, which is required to power the internal components of the machine.
How does a PSU work?
The job of the PSU is to take the standard AC voltage supplied by the wall outlet and convert it into the lower voltage required to power the computer’s internal components. This is done by using a series of transformers, capacitors and diodes.
The AC voltage is first passed through a transformer, which converts it to high-voltage AC. This is then passed through a capacitor, which filters out any noise or ripple, and finally through a series of diodes, which convert it to DC voltage.
The DC voltage is then regulated by the PSU, which ensures that it remains at a consistent level, regardless of the load on the machine. This is important, as it prevents the computer’s internal components from being over- or under-powered.
The PSU also includes a number of safety features, such as over-voltage and over-current protection, which help to protect the computer from damage in the event of a power surge.
