Power supplies are need by many electronic devices for several reasons. Most devices need one or more DC voltages. Only AC power is available at a common household outlet.
Power supplies, among other things, usually must convert AC power to DC power.
AC = Alternating Current
DC = Direct Current
VDC = Volts of Direct Current
Computers, for example, need a power supply to convert 120 VAC line power to 6 VDC, 9 VDC and possibly 12 VDC. You will understand this more fully once you get further into the study of things like trigonometry, the calculus, basic circuit design, etc.
The computer requires it to distribute power to all the components.
Computer components are designed to run at very low voltage - The Power Supply Unit (PSU) converts mains electricity to a lower voltage for use by the computer !
When your computer will not power on. When the cooling fan of the power supply has failed. When the amount of hardware in use in your case exceeds the power capability of your power supply.
You need to make sure you buy a power supply that is rated for your motherboard. Common ratings are 350w, 400w and 500w.
To know what size power supply you need, add up the wattage requirements of all components and add 30 percent.
UPS = Uninterruptible Power Supply
To keep the power supply cool. If there were no fan the power supply would overheat and fail.
Obtain a power supply that has the correct output voltage that you need.
yes there is a need for cost effective power supply like solar energy
When your computer will not power on. When the cooling fan of the power supply has failed. When the amount of hardware in use in your case exceeds the power capability of your power supply.
To add more memory cards you do not need a larger power supply. To add more hard drives for more memory storage space you might need to increase power supply.
to give power in the appliances,that we need in power.
continuous
i need part number of power supply for audiovox lcd fpe2706
The power adapter need 230v, 50Hz supply
Power supply is dictated by your motherboard, simply get the power supply which matches the motherboards pin configuration.
No No No. If your supply can give .2A, and you need 2 Amps, your supply's not going to cut it.
You need to make sure you buy a power supply that is rated for your motherboard. Common ratings are 350w, 400w and 500w.
You need to convert the voltage if your appliance requires less voltage than you power supply. example: appliances is 110V and power supply is 220V.
