Computer power supplies (PSU's) have a variety of ratings including as low as 200 W and as high as 1200 W. The power rating of a computer's PSU depends on the devices installed on the computer.

Is it possible to use two power supplies on a computer?
The computer's power supply powers the computer or any other device. If you want more about power supplies take a look at the link provided below.http://en.wikipedia.org/wiki/Power_supply
Can the power supply cause the computer to be difficult to turn on?
Yes. If the power supply is of a low wattage and has too many pieces of hardware connected to it, it can. Try buying a power supply with a wattage over 300. One thing to check before replacing the power supply is the voltage selector in the back. If you use 120 volt power, then setting the power supply to 240 volts will cause the PC to only get half of the power it needs. External peripherals with their own power supply will not impact the power supply or current in the computer. Printers and monitors usually get their power from the wall socket, not the computer, and the same goes for external modems that plug into the wall. Keyboards and mice take negligible power.
How much does a power supply unit cost?
Computer power supplies will vary depending on the voltage needs of your computer. A general rule is the more components a computer has, the larger power supply it will require and the costlier the supply. Average prices range from $50 to $300.
Is it possible to replace 300 watts power supply to 1000 watts as maximum output?
yes. because the more storage, the more ability the computer has.
How much kilowatts does it take to run a personal computer?
Most computer use anything from 300 watts to 1200 watts.
How much power does a 8-pin power supply connector provide?
300 watts
Can you use a 12 volts 3 amp power supply on a 12 volt 500 milliamp device?
Your power supply can supply 1 A, but your device requires 2 A. So the power supply will be overloaded. So the simple answer is no.
What is the minimum amount of power supply when a PC uses 225 watts while booting but175 watts when running?
Personally, I wouldn't use less than a 300 Watt power supply in that situation. But then, I never use less than a 500 Watt power supply when replacing a power supply or building a computer. The advantage is, the larger power supply can easily handle the load and will not run as hot. Since electronic components typically fail more rapidly when they get hot, the larger power supply will usually last much longer. But that's just a suggestion.
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.
Can you add 600 watt power supply to a computer that currently runs a 350 watt power supply?
Yes you should be fine. As long as it fits in the computer, you're fine. Replace the old with the new one but keep the old one in case the new one doesn't work! 300 watts is fine for replacing something smaller. You should run only one power supply at a time. What this means is that you should replace the 185 Watt supply with the 300. Having 2 separate power supplies creates the possibility of having slightly different values for ground, +5V, and +12V DC. This can cause problems with all of your computer components. Don't use both, replace the old one with the better one. <- There are some motherboards that REQUIRE two power supplies, but you probably don't have one. They're server mb's, and the reason you use dual supplies is, if one supply dies the computer uses the live one and notifies the system operator "one supply just cooked, get me a new one pls." This eliminates a point of failure. If you've got one of these mb's, both supplies have to be the same: two 300w, two 750w, whatever. Really, though, with the amount of juice some of these new video cards pull, I wouldn't even consider installing a 300w power supply in anything except a server, a lot of which are "headless"--they don't have video outs, you control them over your network. Go with at least a 500w supply, and if you might have the need for a dual-head system--two monitors are GREAT, don't let anyone tell you different--go with a 1200w supply.
Is a computer with 300 watts considered good..fast?
Judging the speed of a computer by the size of it's power supply is not a good way of determining it's performance. You must consider the CPU type and speed, Memory type, speed and amount, and other hardware specifications.
Will a 300 watt low voltage transformer power 150 watts of bulbs 250 feet away?
no .it will not supply
