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.
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.
The StarTech 250 Watt will work fine on any AMD computer, but it may not be able to handle a powerful video card.
any power supply with at least 175 watts
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.
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.
Remove and replace the power supply.
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.
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.
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.
yes it will i am running a zotac nvidia geforce 9500 gt on a dell 300 watt power supply and it reqired a 350 watt i have had it for more than 4 months now still runs like a dream
