| | Power supply - Wikipedia, the free encyclopedia |
 | | A power supply unit (sometimes abbreviated power supply or PSU) is a device or system that supplies electrical or other types of energy to an output load or group of loads. | | | Constraints that commonly affect power supplies are the amount of power they can supply, how long they can supply it for without needing some kind of refueling or recharging, how stable their output voltage or current is under varying load conditions, and whether they provide continuous power or pulses. | | | This typically involves converting 120 or 240 volt AC supplied by a utility company (see electricity generation) to a well-regulated lower voltage DC for electronic devices. |

| | Uninterruptible power supply - Wikipedia, the free encyclopedia |
| | Most uninterruptible power supply designs for telecommunications equipment use a transformer along with one or more rectifiers to convert the incoming commercial AC power into a low voltage DC supply, typically in the range of 12 to 50 volts. | | | Older uninterruptible power supply designs that supply commercial quality AC power to equipment contain a motor-generator system with a large flywheel that keeps the generator rotating and producing electric power while an auxiliary motor is started at the moment of power interruption. | | | Modern uninterruptible power supply systems used with commercially available computer equipment consist of: a static (electronic) rectifier, a static (electronic) inverter, a static switch and an energy storage system. |

| | Power supplies, often referred to as "switching power supplies", use switcher technology to convert the AC input to lower DC voltages. | | | The power supply also has a circuit that supplies 5 volts, called VSB for "standby voltage" even when it is officially "off", so that the button will work. | | | The 3.3- and 5-volts are typically used by digital circuits, while the 12-volt is used to run motors in disk drives and fans. |

| | Power Supply Tutorial Hardware Secrets |
| | The device responsible for supplying power to the computer is the power supply. | | | In other words, the power supply converts the conventional 110V or 220V alternating voltage into continuous voltage used by the PC electronic components, which are: +3,3V, +5V, +12V, -5V and -12V. | | | Since linear power supplies still use the 60 Hz (or 50 Hz, depending on the country) frequency from the power grid — which is a very low frequency —, the transformer and the capacitor are very big. |

| | PC Power Supply |
| | Power supplies in today's computers are known as SWITCHMODE or Switching Mode power supplies and require a load to continue to operate after being switched on (the term switching mode actually applies to the technique of A/C to D/C conversion and not to the power up action). | | | These power supplies are called SWITCHMODE or SWITCHING MODE power supplies and must have a load to function -- hence the 10 ohm 10 watt load resistor on the 5 volt line. | | | Many of the R/C folks are converting power supplies for the purpose of driving field chargers and are finding that voltage levels below 12 volts are sometimes insufficient to power their chargers. |

| | Since the power supply is expecting certain sensing circuit feedback to regulate the output voltage, munaully starting it without attaching it to the motherboard could cause damage to the power supply. | | | If you power supply has power connected to it and power switch on the power supply is on, you will see the fan is turnning by now. | | | Once you flipped the power switch on the ATX power supply to on (some ATX power supplies do not even have such a switch), the ATX power supply sends a 5V 720MA current to the motherboard through pin 9 on the power connector. |

| | Keep in mind that the system power supply is a switching power supply type, and won't operate without a load. | | | ATX power supplies can't be wired through an AT switch, which is an AC (120V) hard switch. | | | The power supply operates by sensing the voltage accross the load and shutting off when it goes out of regulation (high), which generally occurs at a frequency of 20KHz to 40KHz. |

| | Of course, the PC is taking some of this power, but the trend has been towards lower-powered cards and drives, making most PC supplies quite large for their typical load. | | | Every time I've done this, the power supply just shut down until I cycled the input power (with the short removed) and there was no other harm done. | | | By the way, another good way to get a 5V supply is to cut the end off of a USB cable, find the red and black wires (make sure with a voltmeter) and connect them to some sort of connector or binding posts. |
