What is the most efficient way to determine whether your power supply is bad?

There are 2 easy ways to check, but both require some extra equipment. The first, and easiest, is to use a power supply tester. If and when you have one, unplug the power, emove the power supply connector from the mobo, plug that into the tester, and the results should be immediate. Most of the testers have different colored LEDs to indicate the results. The second is to connect a different power supply of the same or greater voltage to your computer, if you have one. If your problem goes away, then it was the PSU, if not, keep troubleshooting. Good luck Bob

Why is the computer case the first component you should consider when building a computer?
It isn't! The first is to determine you computer needs; Server, Business Professional, Gamer, Graphic/Video Designer or Editor, etc... Then if you are going to use RAID, and other power constrains. Sum total power consumption +20% and make sure Case with Power Supply wattage is sufficient.
When you bulid a computer what is the first component you install?
Usually the power supply.

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 law would you use to determine the voltage of a power supply?
ohms

J.M Thommes has written: 'Highly Efficient Welding Power Supply'
Is there an energy efficient way to convert 230 V to 12 V DC?
It depends on the output current. In general, the switching power supply is most efficient.
Say the power consumption of my 12v devise is 80 mA or less and the instructions say use a 12v 300 mA power supply and I use a 12v 800mA OK or not?
Generally, yes. If your devise will only draw 80mA, it will do it whether it is connected to a supply that is capable of supplying 300mA or 800mA. The amperage rating on the power supply is the highest current that it is rated for. It will easily and safely provide less current. The load that is connected to the power supply will determine the actual amount of current.
Why is the PC power supply enclosed in a metal container?
For safety, to reduce electrical interference and to aid efficient cooling.
What is the first step you should take when testing a power supply?
You first have to know the type of power supply your are testing. Then you could test whether the power supply is receiving anything from its source. Next check if it is giving any output.
Is there a difference between Laptop Power supply and Desktop power suppply?
Laptop power supply provides a much lower watt output compared to desktop because its powering a smaller and more energy efficient device. Do not try mixing them
Which way does DC power flow?
When you connect a load (motor, light bulb, etc.) in series with a power supply, current will flow, whether AC or DC depends on the power supply you are using.
Is wave power efficient?
wave power is efficient.
