  1. Turn off Your Desktop
  2. Discharge it by pressing the power button after you took the plug out (you may see the power lamp turn on for a second or two)
  3. Open the side cover of your Desktop
  4. Look at the IN-side of where the Power cord Goes into your Computer
  5. You'll see a fairly large box (right behind where the wire went in)
  6. The Box has a harness of many colored wire coming from it
  7. There you will find a label listing all of the information such as Make Model, Voltage, Wattage, etc...
If you are wanting to buy a gaming card, or Video (such as for Media Center use) , it is recommended that you DO buy a larger Power Supply. Otherwise, you CAN buy Video Cards that require less wattage.

Your power supply rating is either on the back of the supply, or in the paper work that came with you computer. You should not need more than a 500 watt supply to run everything on your comp

    But, you stimulated me to re-examine all ot the papers including the pc mag evaluation where i found the info in their review ie, 300 watts. No, thanks to the HP people.

    300 watts is not enough power, especailly if you add periferals (cards) to your computer, power supplies are easy to change, and they don't cost much. you can buy a 500 or 600 watt for 50 bucks, maybe a little more.. I have stopped buying anytning from HP, cause they are getting really cheap with their equpment.

How to check if my power supply is already not ''at the limit''?

1 or 2 extra hdds and ram does not require much extra power and your coolmaster should do the job. But if you intend to use a newer graphic card you should check the requirenments for wattage at your new card manufacturer product specification webpage. I am pretty sure that almost all newer graphic cards require at least 500 watt to run without problem. My advise is to buy at least a 550 watt psu although i don't know what is your hardware. Try to post your hardware specs and calculate for each component (cpu wattage+graphics wattage +etc) your power supply need to be over 50 wattage. Hope that helped!

I want to upgrade video card for my pc(HP Pavillion a1120n) i wanted to know what kind of video card is compitible with my pc. please help thanks. ;)

From what I gather, your computer has a PCIe v1.0 slot for a video card upgrade and comes with intel on-board video. So you will need a PCIe 2.0 video card (v1.0 are no longer available and 2.0 are backwards compatible)

I assume, like most PC's, yours has a 350-450 Watt Power Supply. Check your power supply to be sure, you just can't put any video card, you are limited to the available power from the power supply. If you want a top of the line video card for gaming you will need a more powerful power supply. If all you need is better performance and better video quality (DVI/HDMI) then any sub $100 dollars card will do.

I cannot emphasize enough, check your power supply wattage capacity and the watts required by the new card before buying.

Also, do you have additional power connection from the power supply for the new card? most cards, not all, require a 6-pin PCIe power connector.

For the average user I recommend:

Computer reboots when running games like hoyle ,just set up web cam,for telecall, computer rebooted after a couple of minutes seems like anything with a video type task.Possibly need new video card?

your card is pulling too much power. check the wattage rating of the card and the wattage output of your power supply . good rule of thumb  you want about 20% more that your card rating  450 watt card needs 650 watt power supply to run well. the extra is for your other stuff (dvd burner ,ect)

There is no specific power suppl that you need. The only differce is the wattage 300, 350 , 500 etc. Your motherboard will work with all types not to worry. The only reason you get a higher wattage power supply is if you plug in a lot of stuff. say you have 3 HDD and 2 CDROMS then you would need the 500 Watt power supply.

Upgrading power supply

The next time you get a PSU. Tell them what you have. Apparently you got one that is not compatible with your compaq.The power (500 wattage) will work with your MB.
Get an OEM PSU from Compaq(HP).

Upgrade Video Card

I would recommend picking up a higher watt power supply just to keep up with the changing demands on computers. They are not to do yourself. If still wondering what cards can go with a 300 watt power: Maybe an ATi Radeon 9250 256mb? It seems that a 350 watt power supply should still be minimum nowadays and they are cheap.
