Power supply
A power supple is a device that delivers electric power to an electrical capacity. it also known as PSU, power supply, power pack, power converter.
This term is most commonly which mean that applied the electric power that translates the electrical energy to another one, also for the devices energy. It is control the output voltage or recent to a value.
A power supply may be applied as a separate, stand-alone device or as an integral device that is hardwired to its load. For example, the cases that include the low voltage DC power supplies that are part of desktop computers and consumer electronics devices.
Commonly specified power supply attributes include:

Commonly specified power supply attributes include:
- The amount of voltage and current it can supply to this load.
- How stable its output voltage or current is under varying line and load conditions.
- The amount of voltage and current it can supply to its load.
- How long is can handled without recharging it.
Power Supply Unit Description:
The power supply unit is riding just inside the back of the case. The side of the PSU facing outside the case has a male, three branched port that a power cable, connected to a power source, plugs into. There is also often a power switch and a power supply voltage switch.
The side of the power supply unit facing outside of the computer case. Three branched port that a power cable, connected to a power source, plugs it. There are two switches which are the power switch and the power supply voltage switch. . Connectors at the opposite ends of the wires connect to various components inside the computer. Computer. Some are specifically designed to plug in to the motherboard while others have connectors that fit into fans, floppy drives,hard drives , optical device, and even some high powered video card.
Power supply units are evaluated by wattage to show how much power they can offer to the computer. Since each computer part needs a certain amount of power to function properly, it's important to have a PSU that can provide the right amount. The very handy Thermaltake Power Supply Calculator tool can help you control how much you need.

Types of Power Supply :
- Linear power supply
- Switched-mode power supply
This where can we find the power supply in the computer case . As it show in the picture
Power supply input Voltage:
- 100 to 125 VAC @ 60 Hz
- 200 to 250 VAC @ 50 Hz
Power supply out Voltage:
- + 5 volts
- +12 volts
- -12 volts
- -5 volts
Power supply watts:
The power supply of your computer depends on the wattage supplied by it. There are many power supply calculating software designed to let you get the basic understanding needed for choosing a power supply unit. The computer's hardware configuration and added components define the actual intake of power from the power sully. The optimum power supply is the "recommended wattage". It is an average value of the peak of power used by the devices connected and hardware components. It is important for an individual to establish the power supply needed when building a PC in order to avoid future problems such as unsteadiness, random or sudden shutdown issues.

Here some example of wattage:
This is an example of peak wattage rating. As we can see, the power supply hits the 500W mark for less than a second, then in seconds, proceeds to decline in power capacity. The power output becomes stable at 300W. Under True-Wattage Rating, this model would be designated as 300W instead of 500W.
This is an example of a power supply that does not reach 500W at any time even in the beginning when cold. Its continuous output capacity is leveled off at 200W. Many cheap and none-brand power supplies are marketed this way.
True Wattage Rating is the industry's most reputable way of designating a power supply model's wattage capacity. It is based on the total DC output wattages that a power supply can continuously provide for the system.
This power supply wattage calculator aims to provide a general idea for the selection of power supply unit based on the system configuration with all added-on devices and components. The recommended power wattage figure is calculated based on the peak or maximum utilization power consumption of installed devices or components. Please ensure to use power supply unit capable of outputting over the calculated recommended wattage to prevent system instability, random reset, unexpected shutdown, or similar problems caused due to insufficient power.

Different connectors of the Power supply:
First connector:
This cabal is called a original PC main power cabal. It was made in 1982 and used two cables to the power supply to the motherboard. It comes side by side into the motherboard and also it comes keyed to put it together and sometimes it is not. You always have to remember to plug them in so the black wires are next to each other. It's either "black to black" or smoke and a shower of sparks.

Second connector :
This connector called 4 pin peripheral power cables.
The four pin peripheral power cable dates back to the original PC. It was used for floppy drives and hard disks. It's still around and is now also used for all kinds of things including add-on fans, extra video card power, additional motherboard power, and case lighting. The connector is shaped so that it only fits in one way. You don't have to worry about inserting it the wrong way. People often use the term "4 pin Molex power cable" or "4 pin Molex" to refer to a four pin peripheral power cable. It's not a technically useful term because the 4 pin 12 volt cable is also a 4 pin Molex cable (Molex makes lots of connectors) but "4 pin Molex" is commonly used to refer to peripheral cables anyway.

Third connector:
this connector called a Floppy drive power supply.The four pin floppy drive connector showed up when PCs started including 3.5 inch floppy drives. This kind of cable is also sometimes used as a secondary power cable for AGP video cards which use more power than can be drained from the motherboard slot. The connector is shaped so that it only fits in one way so you don't have to worry about inserting it the wrong way. Floppy cables are built with small connectors and 20 awg wire so they are limited to relatively low current uses.

I descried three example of connector and the other are :
Summary:
The power supply is translating the power from device to another. it have two types. the first one is a linear power supply and the second one is a switched more power supply. it have different voltage the input and out put. How can we know that the power supply is good. if the watts of the power supply is good and still for a long time the more it is good for your computer as i shows upper. the power supply have many of connectors. for example , 6 auxciliary PS , SATA PS and floppy drive PS.
