All you need to know about desktop power supplies
The power supply unit is the most vital component in the operation of a desktop computer. A desktop power supply unit supplies power to the other components in a computer, and converts alternating current (AC) from an electrical outlet to direct current (DC) which is needed by the computer. Power supplies can be inbuilt or external. External power supplies are crucial to the operation of virtually all small electronic devices. They convert high voltage AC to low voltage DC used to power electronic products, like MP3 players, PDAs, camcorders, digital cameras, mobile phones, IT equipment and laptops.
Power supplies are sold based on their wattage, which is their total power output. External desktop power supplies range from as low as 15W to as high as 220W. You need to find one that will power all the components connected to the system. It is important that the power supply can support the various voltage levels and the current supplied. For more advanced computers, with extra features and gadgets, you will need a more robust power supply unit. The power supply should be able to switch voltages and distribute it to all components required. Power supplies these days can provide various output voltage levels, from 3.3V, 5V, 12V, 18V, 24V and even 48V.
Desktop power supplies are available in various models such as switched-mode, linear, regulated and unregulated models. These can supply output voltage in single, dual or triple output models. A switched-mode power supply is a unit that incorporates a switching regulator in order to provide the required output voltage. Linear power supplies are much less efficient than switched-mode power supplies, and adjust the voltage to maintain a constant output voltage. A regulated power supply is a stable power supply that controls the output voltage to a specific value. An unregulated power supply is not subject to the control or authority of a voltage regulator, and the DC output voltage is dependent upon an internal voltage reduction transformer.
Power supplies can be designed to be lightweight and low profile for consumers as well as for industrial use. Good power supplies use surface mount technology and through-hole components, providing maximum efficiency and high reliability. A highly efficient power supply should have universal AC input, be self contained and hermetically sealed (airtight), have product safety certification (UL, CUL, TUV, CB and CE listings), and have a temperature range of -20oC to +85oC. Power supplies should also come with over voltage, over current, over load, short circuit and open circuit protection and thermal fuse protection. Features such as auto-recovery start up and LED indicators are also included in certain power supplies.

How do I use the side band settings on my cb radio and what are the benifits, and should I considder a linear?
I have a new side band radio and tuned a set of firestik duals but dont really know how to use it besides talking to truckers on the road. What are the advantages of upper and lower side band, and how much trouble would one be in for adding a linear amplifier to their radio? What are the benifits of that? And last but not least how do I get the engine noise to go away from the radio?
Sideband is a Mode (or type) of transmission , just as AM is also another Mode.
CB’s that have sideband modes will be switchable from LSB (lower sideband) and USB (upper sideband).
These modes offer greater range than normal AM.
Sideband CB’s will put out 12 watts on sideband whereas AM transmissions are only 4 or 5 watts output.
Due to atmospheric conditions in the ionosphere long distances (500miles +) are possible on the CB band.
While possible on AM , the Mode is more prone to noise and fading effects , combine that with low output power makes it a poor choice for trying for long distance ‘DX’ contacts.
Sideband Mode is much more suitable for DX as it is less prone to distortions of the signal when it is refracted back to earth by the ionosphere. , and the extra power does help.
With the standard power of 12 watts feeding a 5/8 wave vertical I was able to make contacts easily of over 2500miles and I also made some contacts of over 5000 miles.
This is of course using the ionosphere to return the transmitted signals back to earth.
This condition is called ‘Skip’ , even though this is a misapplied term.
Typically without Skip , the standard transmission range of sideband Cb’s with 12 watts is about 20 to 30 miles with a good antenna system.
Using an external amplifier , often called a ‘Linear Amp’ is illegal and is a Federal offense.
Using one and getting caught with it will incur a heavy fine and a police record that never goes away.
Performance wise, it is better to go with standard power and good antenna rather than use a poor antenna and a Linear Amp.
Electrical interference getting into the radio can be cured by installing noise suppressors on the alternator.
Older vehicles with separate regulators etc may need one there as well. , as well as distributers that use contact points.
This will cure most of your noise.
Don’t forget to firmly mount the radio to the car body making sure it has a good electrical connection as well.
Run your + battery supply directly between the battery and the radio , making sure that the cable it doesn’t pass nearby devices in the engine compartment (or the cabin) that makes noise (eg , alternator , electric fans , computers etc)
Make sure your antenna also is properly grounded to the vehicle body with a good solid mechanical and electrical connection.
