what are the four voltages produced by an AT power supply?
97533
+12VDC, -12VDC, +5VDC, -5VDC

Its impossible to tell how many watts the computer is consuming by a program, but there are ones out there that can tell you the voltage.  this is what you need to know.  as far as if you power supply is powerful enough, anything of 450 should be more than enough unless you have some kind of huge amazing rig setup.  Mine is 500 and Im powering 3 hard drives with it.

if you live in the US\n110V for most appliances\n220v/110v for bigger ones\nif you live over in Europe \n220V

I think you meant WATTS versus volts. You will need to inspect your power supply for that information.\n You need to check out he following website, for more info on what you will truly need 250W sounds a bit low by today's standards - http://www.jscustompcs.com/power_supply/

You'll need to provide a little more information in order to have your question answered properly.  AC or DC? Input voltage?  Fixed or variable output voltage? If variable, over what range? If fixed, what is the desired output voltage?  Output current?  How critical is the load regulation?\n\nAs you can see, the answer to your simple question can be a bit complicated :)

What voltage dc, or do you need to be able to vary it?  What current capacity do you need?  What ripple voltage is acceptable?

It is through the Powersupply which converts it to a steady DC current that then goes to motherboard in different types of wires about 24(Some are ground though) for a ATX Computer.

About plus and minus ten percent. That makes it 108 minimum and 132 maximum volts.\n\nMost appliances are designed to expect this range.

you need to describe what you mean by "small" better.\nis it too small vertically, horizontally, or both?\nAlso, how good is your electronics background?\nDo you know how to discharge the CRT and large capacitors so you don't get zapped with 330 to 10,000 volts while attempting to repair it?\nYou also need to define "wavy" better.\nWith the tin amount of information you have given though, it sounds like the power supply is failing, but in which part is impossible to say.

here is one of the datasheets available on the internet:\nhttp://www.ee.washington.edu/stores/DataSheets/74ls/74ls73.pdf

Actually no. I think there is about 5 volts DC. I guess the amount of power available depends on the computer, but it's probably very small. Maybe less that 500ma.

Hi there:\n\nYou can estimate your power consumption using calculations for posted " average" ratings for all the parts of your computer, however, nothing is real, and the power supply rating has nothing to do with the power you are actually using.\n Only the electrical meter on the main line is of any value...\n\nI have answered this question in different forms a few times, and a typical answer is listed below:\n\nHow can you find out how many Watts your PCs power supply uses?\n\nLet's say in an hour, how many watts have been used...\n \n\n\nBest Answer - Chosen By Voters\n\nHi there:\nI looked at the answers above, and only one, CJMT had any inkling of the correct answer \n\n- The only way to know is to MEASURE IT!\nYou can calculate thousands of calculations all day, but until you actually measure YOUR own computer, you are just guessing!\n\nNew power supplies now come WITH and actual Wattage power meter, which is on the back or mounted on a front panel with a plug in cable. Some Motherboards, have a power meter built in as well, and, considering these " new and improved" features, it clearly shows that you are among thousands of computer users who are interested in this factor...\n\nIn the " old " days, you would just get a power " Clamp on " meter of some sort, and clamp over ONE wire of the AC power cord ( this is a bit difficult with normal computer power cords, so you plug in an extension which has the the wires separated, and clamp the meter over ONE of the wires.)\n\nNow you can purchase easy-to-use plug in-the-wall meters that have digital readouts. \n\nSimple.\n\nYOU MUST actually measure your wattage - for example, if you have an 800 WATT power supply, this means nothing, except that the power supply " CAN " supply 800 Watts if it " has to " -- you could actually only be using 289 Watts of the available 800.\n\nIn order to really know what your " computer " is costing in terms of power, you should plug in the monitor, the CPU box, the speakers, the printer, the modems, power adapters etc. etc. TO A POWER BAR, and then measure the actual total to the wall plug.\n\nListed below are links on the web to typical measuring tools that are commonly available. You can check out stores and electronics and computer outlets in your area, once you know what you are looking for. If you know an electronics guy or a hydro guy, he could just let you use a clamp meter in a few seconds to get a reading, and save yourself a few bucks - but the $30 home units would come in handy to measure anything in \nthe whole house -- well worth it !\n\n\nPower Supplies with WATT METERS\nhttp://www.highpowersupply.com/product-ps-hpc480102df.html\nhttp://www.newegg.com/product/product.asp?item=N82E16817171001\n\nKill a Watt Meter\n\nhttp://www.gooddeals.com/shopexd.asp_Q_id_E_119\n\nBriggs and Stratton Meter\n\nhttp://www.northerntool.com/webapp/wcs/stores/servlet/NTEprodprint?productId=200326720&p\n\nrnbr=1704700&storeId=6970&catalogId=4006970&langId=-1\n\nSAFE HOME 3 products\nhttp://www.safehomeproducts.com/shp2/shpsearch.asp?source=adwords&kw=wattage+meter\n\nProfessional Watt meters\nhttp://www.testequipmentdepot.com/amprobe/clampmeters/digitalac.htm\nhttp://www.testequipmentdepot.com/fluke/currentclamps/330series.htm\nhttp://www.testequipmentdepot.com/hioki/clampmeters/3280.htm\n\nThere are hundreds of other models and manufacturers available, and since millions of people are interested in actually knowing where the high cost of power is being used in their homes, I expect to see hundreds of more products available\nat lower and lower prices as manufacturing gears up.\n\nHope this helps\n\nrobin

I have one that reccomends a 350W power supply running off of a 250W but then I don't have all of the bays full on that compuer.  And it's my dads and it's old so I don't really care either way.  However on my PC I have a 500W power supply and I got it for $21 and I would recommend that you do get a better power supply if you are going to play a lot of games.  That being said... the X1300 isn't that great of a card, I would have gone with at least the X1600 if not something in the X1800 series.\n\nOh, here's the link, http://www.newegg.com/Product/Product.asp?Item=N82E16817255010 to the power supply that I got, out of stock as of this post (make sure your motherboard is compatible with standard ATX power supplies, some aren't like Dell PCs).

To measure ohms, DCV, ACV, Amps or what????

More than likely it is your power supply. Either get a good power supply tester or if you have another power supply try that. Good Luck! ;)

In the description below it states the AGP bus is only up to 4X. I'd go for an ATI, check site:

Each Card not only needs its own power source equivalent to 2 molex plugs with adapter, but the motherboard needs an additional plug too. Together this is 5 molex plugs. The best bet is to get an SLI ready power supply which start at 500W.\nAn SLI ready supply will have 2 special PCI-E connectors so you don't need the 2-molex to PCI-E adapter. This Antec is proably the cheapest you would want to go with over a grand of video cards in a computer:\nhttp://www.newegg.com/Product/Product.asp?Item=N82E16817103931\nThe best brand to get would be a Power PC and Cooling:\nhttp://www.newegg.com/Product/Product.asp?Item=N82E16817703001
