The load size in watts is what determines the size of UPS needed. Add up all of the load wattages that you would like to have an uninterrupted power supply. Some UPS units are rated in VA output, for the purposes of this calculation VA is the same as watts. There are many UPS calculators on line if you need any help deciding what to connect to it. Remember the larger the UPS the more the cost is going to be. Read the discuss page for calculator.

Formula for working out cable size?
There is actually no specific formula used to work out cable size. In order to determine the type of cable you need and the size you need, you need to know the source of the supply, the voltage of the system, the ambient temperature, and the method you plan on laying out the cable.
What breaker size do you use for a 270 Kw power rated equipment and power supply of 380 vac 3 phase?

How much power required to propel a ship while resistance is neglected?
The power to propel a ship is dependent on a number of things besides resistance. You must consider the size of the ship, its weight, and its passenger's weight before you can determine the power required to move it.
How does low power factor effects conductor size?
A load with a low power factor draws more load current than necessary, so the supply conductors need to have a greater cross-sectional area than would otherwise be necessary.
How do you determine correct size varistor for protect system which work with 220 v?
How i determine correct size varistor for protect system which work with 220 v AC?
What is the purpose of Powerware ups?
An UPS is an uninterrupted power supply. They are connected to electronics and if the power goes out the UPS battery kicks in for continuing usage. Depending on the size of the UPS battery one may have time to shut down or extra time for additional usage.
Does a solar power generator store enough energy to supply power to an average house?
Some of the solor power generators are larger than others. Most of them will supply power for a few hours or days to an average house. Depending on the size of the solar power generator will determine whether or not it can store enough energy to supply power to an average house. Most likely if you get a very big one it will produce enough energy.
What are the specifications and size of a motherboard or power supply?
The "form factor."
Why does your computer mouse and keyboard not work anymore after changing the power supply?
Possibly not enough output power. Are you sure that you got the right size power supply?
What determines the physical size of a power supply and the placement of a screw holes?
Case form factor determines the physical size of a power supply and the placement of a screw holes. It can be ATX, microATX, BTX and others.
What is an external power supply?
A power supply that is designed to be outside the case of the computer. Most laptop computers use an external power supply rather than an internal one to reduce size and weight while the laptop runs on battery power.

What power supply can fit into a dell dimension 4550?
So i have a dell dimension 4550 and need a new power supply. I have two I'm looking at, a Logisys 480 Watt 20+4pin ATX Power Supply and a Athena Power 400 Watt 20+4 pin Micro PS3 ATX.I want the one with the most power, but i don't want to do any case cutting for it though. Does anyone have any way to determine the size of the case for a 4550. It would be greatly appreciated
What size power cable do I need with a Crunch Power Zone P11002 amp?
This unit will require the PWM power supply system
What pieces of information are needed before selecting a power supply?
The main piece of information needed is the load wattage or amperage that will be connected to the power supply. Once this is known the power supply of a greater size that the load should be chosen. Also with this information the size of the wires can be calculated from the power supply to the load. Too small a wire will create a voltage drop at the load end of the circuit. This will cause under performance of the load.
