Power supply units are rated based on their output and efficiency. When more equipment is connected, a higher output power supply is needed.

Dual power supply?
Dual power supply is used to describe a computer system with two power supply units (PSU's). This is to provide extra power for the computer's internal components.
When you purchase a power supply the output is measured in which units?
Watts.
What is the best choice for a replacement power supply for power supply ratings?
You need to make sure you buy a power supply that is rated for your motherboard. Common ratings are 350w, 400w and 500w.
Full form of UPS related computer?
UPS = Uninterruptible Power Supply
Can you use a ac to dc power supply rated 12 V at 1.0 A for a device that needs 7.5 V at 1.4 A?
You can't. Buy the correct power supply.
Why is that when an electric bulb stay just as its bright when connected to a parallel circuit?
To operate at its rated power, a lamp must be subject to its rated voltage (the supply voltage). As each branch of a parallel circuit is subject to the same voltage (the supply voltage), each lamp will operate at its rated power.
What voltage is the power supply for a quest 2wire gateway model 2700HG-D?
The 2wire 2700 and 2701 models both use a 5.1 volt power supply rated 2 or 2.2 amps
Why increase the power supply on a desktop computer?
Generally you want to increase the capacity of the power supply (rated in watts) if you want to add more components to the computer which require substantial amounts of power, such as graphics cards. You may also in some circumstances find that the computer has an under-specified power supply installed when it is sold/built and so it will need to be upgraded just to be able to power the existing components.An under-rated power supply will manifest itself through system instability (randomly resetting or turning off when you do something that places a load on the system).
Will a 15DC 1000mA power supply work on a device needing 15DC 1500mA power supply?
Your question is confusing, but if you are asking whether you can use a 9V/250 mA adapter to supply a load device rated at 5 V/1000 mA, then the rule is quite straightforward. The adapter's rated output voltage must match that of the intended load, but its rated current must exceed that of the load. So in your example, you cannot use the adapter with the intended load.
Can a device requiring 12 volts and 3 amps run with an adapter providing 12 volts and 2 amps?
No. Your power supply must be able to supply rated voltage (12 volts) and rated current (3 amps).
A device that can protect a computer from power surges and lightning is a?
That would be a "surge protector". Note that many UPS (uninterruptable power supply) units include this functionality too.
Can you use a power supply with more amps and not fry the unit?
you will need to be allot more specific on what you are trying to do here. what is the difference in amps. what is the device Generally speaking it is good practice to only use the power supply that the device is rated for. the biggest issue you will have is this Power = voltage * current (simple version) if the power supply you had was 12v at 1 amps then you ca supply 12Watts of power if the power supply you had was 12v at 10 amps then you can supply 120Watts of power Just because you can supply 10 amps, and all you need is one, means your power supply is bigger than it needs to be. The device will draw what it is intended to draw. Just make sure the voltage matches.
