Encyclopedia power supply unit. A system that converts AC current from the wall outlet into the DC currents required by electronic circuits. A computer power supply converts AC into multiple DC voltages. For example, 12 volts is commonly used for drives, while 3.3v and 5v are used by the chips and other motherboard components. Switching Power Supplies. Power supplies known as switching power supplies are commonly used.

Power supply Power supply. A power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads.

- The power supply as its name might suggest is the device that supplies power to all the components in the computer. Its case holds a transformer, voltage control, and (usually) a cooling fan. The power supply converts about 100-120 volts of AC power to low-voltage DC power for the internal components to use.

Regulated power supply Regulated power supply. (see clock-wise) Step-Down Transformer, Potentiometer, Switch and Embedded Circuit board for making a Practical DC Variable Regulated Power Supply. A regulated power supply is an embedded circuit; it converts unregulated AC into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits.

What is power supply unit PSU? Confidence votes 29. A PSU is a part of a computer that supplies power to the rest of the computer. A cord is plugged into the wall that leads to the Out side of the computer and is plugged into the PSU. The PSU then distributes the power through out the system internally, to hard drives, DVD/CD drives, floppy drives, GPU's, the motherboard and any other parts as well.

Power supply unit (computer) Power supply unit (computer) A power supply unit (or PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.

BIOS for Beginners When these settings are not properly configured, the result can be systems that do not shut down correctly, or that enter or awaken from the Standby or Hibernate modes improperly. Since Windows has built-in power management, you'll want to disable all power management in the BIOS. Otherwise, the two fight with each other, and neither works properly. Motherboard manufacturers don't assume that everyone is using Windows, so many of these settings exist for non-Windows users.

Power Supply Since the power supply is the first place an electronic device receives electricity, it is also the most vulnerable to power surges and spikes. Therefore, power supplies are designed to handle fluctuations in electrical current and still provide a regulated or consistent power output.ower Supply. A power supply is a hardware component that supplies power to an electrical device. It receives power from an electrical outlet and converts the current from AC (alternating current) to DC (direct current), which is what the computer requires.

Power Management for Windows Drivers The power manager instructs drivers when to prepare their devices to enter a low-power mode, and drivers receive notification from the power manager when their devices are turned back on. Drivers are responsible for reporting their power capabilities to the power manager. Drivers have the option of detecting when their devices are idle (and can be switched to a low-power mode) or relying on the power manager for such detection.
