Yes you can, but there is a lot more to it then that, you need to know what power connectors are on the motherboard, so you should buy one that is made for your model

if you don't know motherboards. If its a dell, hp, ect, you can go online and find a site that asks

for the brand and model and will give you a few choices of PSU's to use, or get it from the MFG.

You just can't under supply the computer.

What is the recommended wattage capacity for a power supply for?

If you have a 500 watt power supply and you want to put in a new video card. On the video card's box it will tell you how much power it needs. If it requires less power then you don't need to worry. If it says it requires more, you'll need a bigger power supply with large wattage otherwise you'll kill your computer.


What is the amount of power consumed by a 60 watt 220 volt lamp when it is connected across 110 volt supply?

What is the amount of power consumed by a 60 watt 220 volt lamp when it is connected across 110 volt supply?


What other appliances would be similar in terms of power consumption to a 1200 watt PSU computer power supply?

Any other appliance that runs on 1200 Watts would use the same amount of energy in an equal time. But computer power supplies do not always run to their full capacity, so 1200 Watts is the maximum output it can supply if needed, in which case it would probably take 5-10% more than that from the supply. Appliances using a simlilar power are a toaster or an iron.


Will an American computer with an 800 watt power socket work in a UK 240 volt power supply?

Some do and some don't. You need to check the power supply's specifications. The input voltage and frequency range is normally stated on a label visible from the rear of the computer. Many modern PC power supplies will accept a range of input voltage and frequency, or at least have a switch to chose between 110V/60Hz and 240V/50Hz.

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.


How many watts should you look for in a power supply for desktop?

You need to know what kind of voltage all your computer parts work at. There's not really a general Watt power supply that you should look for.


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.
