Best Answers: How can I lower the cost of this system?
I'd try for a cheaper case, myself. The outside can look totally pedestrian, but that doesn't mean the inside can't scream! After that, maybe you can compromise a bit on the CPU or motherboard. Perhaps you might even consider a 600W PSU. Other than that, all this stuff is pretty much necessary.
First your speaker doesn't have any watts, it consumes watts from an amplifier. The "1000w" is supposedly the amount of power the speaker can handle from an amplifier but it's not likely true nor would you want it to be. People seem to think this rating has something to do with the speakers output capability but it doesn't. The amount of power consumption an amplifier draws is a function of its output. Usually a typical amplifier will draw some nominal amount of power at idle usually 30 ~ 40 watts. At very low volume this will increase only a little and at very high volume it will increase more. A class AB amplifier is usually about 50% efficient so that means it draws about twice as much power off the line as it supplies to the speaker. So a "1000w" amplifier if class AB would draw about 2000 watts off the AC line. That's over 16 amps so many typical home 120 volt AC outlets would not be sufficient to supply that much power continuously. So yes, volume does matter, the volume can control it from drawing very little to more than your AC outlet can supply if you really did have a 1000 watt amplifier. Don't put so much thought into power especially huge numbers like 1000 watts. No single speaker can utilize this much power. Generally the less power required to get a desired output the better. The more power in the voice coil the greater the temperature variations and thus the higher the compression and distortion. If you want to play loud you use an array of speakers with each driver using only a little power, you don't use a single speaker that claims to be some huge wattage rating. This is all marketing BS! The speaker power rating has nothing to do with what it can deliver. Run away from speakers making such high wattage claims, they're usually junk. Now if you are talking about a "1000W HTiB" then I have news for you. You have a total of perhaps 100 ~ 150 watts distributed among all the speakers combined. The makers of these Sh!t boxes have all sorts of ways of twisting the ratings but mostly they just flat out lie about the capability of the system. Either way, power in audio is not a constant, it's a function of actual work being done so if the system is working hard and playing loud it's consuming more power and if it's idle or playing softly it's consuming very little power. Edit: This system will supply a few watts only. The small speakers can only handle a few watts. If power consumption is your concern, don't worry this thing draws and supplies almost nothing, no where close to 1000 watts. Frequently the ratings on these things will be peak to peak at high distortion (like you said 10%) and all the channels will be summed. You can't sum all the channels because the power supply can't support it. A typical situation would go like this... 50+/- a bit watts/ch rms @ 10% THD (single channel driven) They start with that, multiply it by 2.8 to get peak to peak watts of 140+/-. For a 5.1 system they multiply that by 5 to get 700+/- watts. Then the subwoofer has about 100+/- watts rms @ 10% THD and multiply that by 2.8 to get peak to peak. They then sum it up for about 1000 watts but the power supply is good for about 150 ~ 200 max. The amplifiers are usually class AB so the real total power output all channels driven is about 75 ~ 100 watts due to the 50% efficiency of class AB amplifiers. If the amplifiers are class D they may be over 90% efficient so in that case you might get a total of 180 watts or so. Thing is, watts is not a measure of performance anyway. You need watts to get high output generally but with bigger more efficient speakers you don't need much power. These little tiny speakers have very little surface area so they don't couple well to the air and thus they need more power but they also sound harsh and compressed. You would be far better off getting a separates system with bigger better more efficient speakers and a real receiver. mk
Get a 520w power supply, the one you have is way overpowered for the components you have listed. I have a 520w powering my 4850, which consumes much more than a 5770. The motherboard seems way overboard for your needs, It includes support for 4 graphics cards, which is evidently not in your needs. This one would save you a lot of money, and I've had a lot of luck with Gigabyte motherboards (4 of them) : http://www.newegg.com/Product/Product.aspx?Item=N82E16813128392 Finally, you could get a less expensive case.
I would more or less agree with Lucy that you should shut it down now and then. Memory leaks are a real possibility. I disagree that 75% is normal for a computer not doing anything!!! However, you need to know that your comment, " I'm confident I have no viruses since I rarely download anything." is false confidence. You don't know what you are talking about. You do not have to download anything at all in order to pick up malware. As long as you are plugged into the internet, you can pick up malware, although a good anti-virus program, like Norton, can help. Try this for kicks. Go into the Task Manager buy hitting ctrl-alt-del simultaneously and go to the memory tab and watch it display the 75% usage. Now, unplug your ethernet cord from your computer and see if it makes a difference. If it goes down, way down, then you know that you have been giving computer time to spammers for free. If it stays at 75%, then probably not - you are lucky!
