Upgrading power supply

Ihave a compaq motherboard #252608-001 with 24 pin and 4pin processer plug with a basic nvida vidieo card , I wanted to put in my nvidia 7600 gsoc vidio card but it states that the min req are that a 350 watt psu is needed, my system has a 250 watt in and works fine, however i went and bought a psu of 500 watts and installed into my computer but get no response (no power, no led lights on mother board)
when i rehook my 250 watt supply everything runs fine , is it posable that the motherboard wont take a 500 watt psu?
when i look at the 24 pinn plug the coolmaster 500 watt plug has pinns in all holes, the first 500 watt antec psu had one pinn missing from top row , and the 250 psu that works the computer with no problems has one pinn missing from bottom row.
all psu where tested and checked out good
with only two wires to motherboard its hard to mess up, i know thier in the coresponding holes but just get no response from motherboard or psu!
any suggestions?

thank you

Re: 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).

I am replacing a motherboard with a G31-M7 TE and find that my existing power supply has a 20 pin plug consistant with the old motherboard but the new one has a 24 pin socket. Why is this and do I need to...

New motherboards have a 24-pin power connector. Here is a diagram of both plugs:


You can see that the two are almost identical. The extra 4 pins on the 24-pin connector provide extra connection points for a few voltages. Newer boards and processors need more current, and the extra pins were added to prevent overloading.

Adapter cables are available to go from your 20-pin power supply plug to the 24-pin motherboard connector. Here's one from TigerDirect, and other vendors have them as well. If you're not making other changes than replacing the motherboard, you shouldn't need more than this adapter.

If you are upgrading your processor along with the motherboard, you should probably replace the power supply too. Older power supplies are often in the 300-watt range, and this is too low for reliable operation with new processors, motherboards and video cards. A new 500 or 600-watt supply is not expensive, and would give you the 24-pin power connection the motherboard needs.

Hope this has helped. Thanks for using Fixya!

Cpu fan stop few second after starting pc

Hello,have you installed new motherboard or CPU?
Follow these steps again
1) Disconnect the power cord from the back of the computer & open up the case.

2) Wear an anti-static glove or at very least discharge your static by touching a metal surface or power supply

3) Disconnect the main 20pin ATX power connector from the motherboard & the square 4pin ATX2 power connector

4) Remove any PCI cards you have & disconnect ALL drive cabling from the MOTHERBOARD. Also disconnect any internal USB fly leads from the motherboard.

5) You should now have ONLY the cpu+heatsink/fan, memory & video card installed. Locate the round silver battery in the bottom right corner of the board. Just below it, you'll see a plastic jumper cap. This cap should be covering 2 pins (pins 1 + 2) with pin 3 bare. It will be marked JP1. Move the jumper to cover pins 2-3 instead. Leave in this position for about 30 seconds, then return the jumper to its original position (pins 1-2).

6) Reconnect the square 4pin ATX2 power connector & the main 20 pin ATX power connector. Make sure that the case speaker or buzzer is connected also.

7) Make sure the only external devices connected are the keyboard/mouse & monitor. Reconnect the power lead & power on the system

Let me know what happens

I don't have the manual for 277498-011

As for the Power Supply 99% sure it is an ATX which as long as you get the same Watt as the existing you will be okay. Make sure you look at your existing connectors to see if you have a 24 pin or 20pin motherboard and 4 pin or 8 pin additional power plug (black and yellow wires) and the new power supply has matching connectors....older ATX supplies have only 20 pins, but there are converters from 20 to 24 pin available.

Watch for the new power supplies and your drive connectors as some of the new power supplies have limited ATA plugs...if you have a lot of ATA devices you might need SATA power convertor plugs or ATA splitters to get all you ATA devices up.

I change the power supply but i have a little problem. The new one on the ATX power connector have only 19 pin then 20 old one plus extra 4 pin for something else. The new power supply in Rosewill...

The extra 4 pins on the power supply's atx connector is for new motherboards that require 24pin power supplies. If your motherboard has a 20pin port, then only connect the 20pin portion of your power supply connector.

If your power supply has a 24pin fixed connector that can't be split into a 20+4pin configuration, and your motherboard doesn't have space to let the extra 4pins on the side, then you might want to consider returning the power supply and change it for one that can be used as a 20 or 24pin. Otherwise you will need to cut the extra 4pins apart.

Cant get any picture through the moniter tryed agp vidieo card and pci vidieo card still nothing the motherboard is out of emachines c2280 L7VMM2

Sounds like you have a bad power supply or motherboard. The power supplies in eMachines are not known for reliability, so try testing the system with another one. If you still have no video, you should replace the motherboard.
