This cannot really be answered. There are many variations of power supplies. Here are some of the considerations:
1. Wattage. Computer power supplies come in different wattages.
2. Rail configuration. Power is divided into rails. There are 3 main ways this can be accomplished. The simplest is to put everything on a single rail. This violates the power supply standards, since there should not be more than so many watts on a single rail. The main concern there is a fire hazard, though ripple (electrical noise) can be another concern. They are the easiest to hook up since you don't have to worry what wires go where for the computer to operate, so long as you don't overload the wiring. The opposite extreme is a multiple rail configuration. Those can provide the cleanest voltages, but you have to be careful in how you distribute the wires, and they are expensive. Most common are split rail configurations where there is a single rail, but separate filters and regulators that can power down the entire power supply should a single wire be overloaded. They can been the biggest pain to hook up if you are running close to the maximum.
3. Fan configuration. While fans in the back are traditional, the new thing is to use larger and slower fans on the underside to reduce noise. This is often coupled with automatic fan controls as well.
4. Types of plugs. If you use SATA drives or high end video cards, you have to have compatible plugs.
5. Energy efficiency. There are now 80+ power supplies that are very energy efficient. They cost more than power supplies that are not rated as such.
The most common types of power supplies are Antec power supply and Enermax power supply.
AC, or alternating current and DC or direct Current
Their are
ATX and mini ATX.
ATX and mini- ATX
Almost all digital electronics use a AC to DC power supply. Digital electronics cannot handle AC. all electronics device having battery powered are using DC power supply http://www.wzmicro.com
The sun supplies different kinds of energy including electricity, heat and power sources
There are several different kinds of power converters. I have seen the APC Replacement Battery, the American Power Conversion, and there is also the power supply, and the phone converter. Some converters have different voltages.
UPS = Uninterruptible Power Supply
power supply is a device that supplies electric power to electrical load
all about regulated power supply
Advantage of regulated power supply.
any power supply with at least 175 watts
variable dc supply are used to get desired amount of dc supply
If it is a computer power supply it is the box that gives the computer its power from the outlet.
