That's not really a question, but if you're thinking of the price it would be somewherer from $150 -$250 depending on which brand name...
Most computer use anything from 300 watts to 1200 watts.
Remove and replace the power supply.
A computer consume an average of 700-1000 watt. It varries due to the efficiency of computer and other extra audio devices, power supply Eg:ups, home theatre, speaker etc..
It depends on what PC, but your power supply will normally say on the side of it. Most commonly is between 200-400 watts Power consumption is a combination of several things. The power listed on your power supply is the amount the power supply is capable of handling. The actual power consumption of the computer depends on what processes are being used, for example word processing will consume less power than heavy gaming. However, one can expect average computer use to consume 150-200W.
It will all depend on which motherboard you have and how many ancilliaries such as disk drives and Optical drives you are going to use. Check with makers of your computer motherboard. These days the average suitable supply is 450Watts. 750 Watt or greater, for gaming computers.
No. A power supply has to power all componets in a computer - processor, disk drives, optical storage, memory. So, a power supply has to be more powerful. Exact value depends on how much power all components use.
Most computer use anything from 300 watts to 1200 watts.
It is not recommended to replace a 350 watt power supply with a 300 watt power supply, as the lower wattage may not provide enough power for your components. It's best to match or exceed the wattage of the original power supply to ensure proper functionality of your system.
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.
The StarTech 250 Watt will work fine on any AMD computer, but it may not be able to handle a powerful video card.
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.
any power supply with at least 175 watts
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.
It's not recommended to use a 350 watt graphics card with a 300 watt power supply because the power supply may not be able to provide sufficient power for the graphics card's requirements. This can lead to system instability and potential damage to components. It's best to use a power supply that meets or exceeds the power requirements of the graphics card.
If you mean how to use a resistance of so much power then it can be easily done through a step-down transformer which lowers the voltage supply and hence the power.
Remove and replace the power supply.
It has to fit in. But the case must not have an influence on the Watt number of your power supply. How much Watts etc you need for your computer depends on the hardware you have in it. The case can be to tight for bigger power supplies (with more Watts). While the width of power supplies is mostly the same, the length varies often.
