i have a 500 watt AVR. my speakers are rated 280W. can i save on my expenses if i would shut my speakers off?

Absolutely you can save your expense by saving power.  If you turn on your speakers, more power ll be consumed from your SMPS. so definitely you can save your expense by shut off your speakers.

I would get a 500 watt inverter to have some safety, you figure with volts times amps but if it uses a motor the starting current can be 5 times the running amps.

I'm a certified audio engineer and audio enthusiast, and would love to help!\n\nThere could be a multitude of problems here, and the fact that you are describing a speaker set-up for PC makes things a little more complicated.\n\nFirst question:  What makes you think your rear speakers aren't working?\n\nIf your answer is "There is no sound", this is doesn't neccessarily mean your speakers aren't working.  Sound is not supposed to eminate from the rear speakers 100% of the time.  They add ambience and directional cues.  Also, sound will not come from the speakers if the audio for the software you use isn't encoded for 5.1 (or greater) audio.  \n\nThe same is true for Home Theatre set-ups; not all movies are encoded to tell the surround processor to send audio signal to the rear speakers\n\nThat said,\n\nThe first thing to check:  Make certain all of your speakers are connected propery.  Depending upon what sort of system you purchased, some speakers can be directly connected to your soundcard, some need to "daisy chain" in order to work.  That is, one speaker must connect to the another, and that connects to another, etc.\n\nNext, check all your volume controls.  How many do you have?  Every single one must not only be on (not muted) but the more controls you have, the more you need to be aware of how they're set.  In other words, the first volume control should be at max, or near max to send a strong signal to the next control.  This will represent the loudest level you want to hear.  The next control should be slightly lower or equal.  If it is greater than the first, then you increase hiss as well as volume.  Not good.  Continue until you get to the last.  This will be the master volume, and this is the only control you should use to adjust volume.  \n\nYou have control panel volume.  Do your speakers have their own volume knob?  What about the sound card- is there a control you need to activate?\n\nOf course, this is assuming all the software and hardware is compatible with one another.\n\nIf possible, swap the rear speakers with your front speakers, and test to see if they are working.  That would eliminate defect in the speakers, as well as the wire leads connected to them.\n\nFinally, make certain you have installed all required drivers to run your sound card.\n\nIt's a little difficult to offer advice without knowing more specifics regarding what sort of system you have.  Hope this helps a little.\n\nGood luck.

A good, used 30watt bass amp is probably worth between $80 & $100. Of course, I'm just guessing here. I haven't seen what your idea of "in good condition" is. Try asking around the local music store. Ask them to sell you a good, used 30w amp. This way you'll get an idea what their getting for the same item. Ampeg is a good name.

get an uninterruptible power supply...

You'll likely get various answers as I can already see.  No, it doesn't really damage it but think about this, you turn it off and then immediately turn it back on, one minute 500W (my power supply) of energy is flowing through your system and then not and then immediately it is again.  I hold the belief this causes unnecessary wear and tear on the system and if you are only going to be away from the PC for a short time, put it in standby or for longer times hibernate and shut down at night (or whever you sleep).  But, if you are having a problem with Windows and task manager is not responding, press the reset switch (if you have one) which is a far better solution than turning it off and immediately turning back on again.\n\nJust my take.

Depending on how much you "strain" your computer, the RAM will get more and more fragmented thus the performance will get worse.\nIf you don't need your computer running at night time, shut it down! This will save energy and spare the components.\n\nThere is still a common misbelief that turning the computer off and on will lead to a higher power consumption caused by the boot process. Not with todays computers!

No, not really. you'd probably end up overloading the the computer even if you could plug in anything.

There is a lot of factors that could go wrong, so if you are really worried about it, you should probably shut down.  Surge protector, properly grounded electrical system, and other factors will make it less risky though.  It may be worth the risk.

Aboslutely, provided the fans are for 12V service.  Leave the secondary center tap unconnected, and put each end of the secondary to the AC input of the rectifier.  The + goes to the red lead of the fan; the - goes to the black lead (traditionally speaking of course.) Now the supply will be very ripply, with a 120 Hz waveform which could be more than a volt.  If you put a 470uF 35V capacitor across the plus and minus of the rectifier, you will smooth out the ripple, but increase the voltage above 12 volts.  Make sure the fans can take the increased voltage.  Transformers are rated at the RMS output at the 3 amps in your case.  The peak voltage will be around 1.4*12.6, but in practice I have never seen it go above 15 V with a load.  Therefore at 1 amp, if you put a cap on the supply, it may produce excessive voltage.  Check it with a voltmeter-- you may luck out.\n\nI have been in a similar situation.  Get a 5 watt resistor at maybe 1 to 3 ohms.  Insert it in series between the capactitor positive and the fans wired in parallel.  When running, use a voltmeter on the fan circuit.  Increase the resistor till you get 12V or thereabouts.  The resistor will get hot, so leave the leads long and connect them to a terminal strip or block if possible, and mount it in the airstream.\n\nCheck out the LM7812, however, at 1 Amp.  Google it, or check out jameco.com for the part.  Put a 470uF at 35 V at each end of the regulator to keep things very smooth.  Your fan will run perfectly with the voltage regulator.  Be sure to mount the tab on a heatsink to keep it cool since you are running it at full capacity.

It should not be that much to run your computer. The main power users in a home are: 1. Refrigerator \n                                              2.Washer and dryer\n                                              3. Electric heaters \n                                              4. Electric ranges\n                                              5. Freezers\n                                              6. Air conditioners\n                                              7. Dish washers\nAnything with a heating or cooling element will be a big factor in you electric bill. Things like lights and computers do not use much energy so if you leave it on overnight, do not fret about it for that reason alone.

The 6800 is not a power hog like some cards.\n300w should be enough to meet the requirements for the card,\nhowever if you have several devices being powered ie; dvd Rom, CD burner, multiple HDD's etc. You may want to go to 400w +.\n\nBottom line: It should be OK. even though the official min. wattage is 350w

Disconnect/turn down the sub woofer, \nor use a smaller speaker\nor connect the output to a stereo and use the equalizer to turn it right

If you are having an ATX system. You just press the power swith of your cabinet to shut down the system.

Try checking with Crutchfield.  They have a big selection of speakers, amps, everything

You should, because you can save electricity :)
