In my Compaq Presario i have an Asus mobo with a weak 250 watt power supply. I Bought a new power supply for my new graphics card. My mobo has a 24 pin connector on it but the current power supply only has 20 pins. My new one has 24, so can i hook all 24 up or do i have to keep it at 20?

Okay... My ASUS MOBO has a 24 pin connector. The power supply that came with the computer only has 20 pins going in to it. IDK why its like that but thats how it came. My new PS has a 20/24 pin connector so i can just hook up all 24 instead of 20? This is the link to see my MOBO http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&cc=us&product=1817035&dlc=en&docname=c00496280

The color codes can be compared between the new 24 pin connector, and the older 20 pin one.
Then, simply snip off the end four connectors, unless they will spread to slide on with the rest of the connector, simply hanging over teh end! Just watch the polarity of the harness plug that plugs into the man board, before you power up, make sure you got it right!

If you have a motherboard requiring a 24-pin cable for your power supply, it will only WORK if you use a PS with 24 pins. You will not be able to use a 20 on it anyway. It won't fit. 20 to 20 and 24 to 24 . . . there is no way around it. And remember to hook up that 4-pin cable too or you may have undesired operation when you go to reboot your PC with the new power supply. *grins* Hope that answers your question.
There are power supplies that come with a break-a-way 4-pin for motherboards with 20-pin connectors. I have bought several of them for the computers I build. It's awesome if you made an oopsy while shopping and bought the wrong thing. Thankfully, you can just pop off that 4-pin extra and can use it then. Check to see if you can do that with yours, assuming your board requires the 20-pin.

The 24 pin connector has on it's end, 2 black and 2 yellow wires. They are the ones that should hang over and not connect to the 20 pin receptacle on the mobo.
Just get a 2nd opinion before trying it... It works on mine.
The black and yellow wires provide more conductors for the current needed on hi-end mobos.

Only 20 pin power supplies can work with a 20 pin mobo. Some power supplies have a special connector so they can satisfy both needs, but some do not. A connector is also sold to fix that problem, you can get it at your local best buy, or you can buy it from newegg; with the link being: 20 to 24 pin http://www.newegg.com/Product/Product.asp?Item=N82E16812201001 or 24 to 20 pin http://www.newegg.com/Product/Product.asp?Item=N82E16812145001

I hate to tell you this, but remove that power supply and RMA it. Get the proper supply for the mobo, in other words make certain you get a 20 pin connector on your new power supply. Don't try to use the one you have, you WILL destroy the mobo!

you have to keep it at 20, i bought a psu like this and i was able to unattach the 4 pins that i didn't need from the connector.

If I was you! I would go to the website (ASUS.com) of the mother board and send them a e-mail ( click on tech support or contact us) give them your new power source model number and the watts, details. Then ask them if it is compatible. That way you should be OK if it fries. They will hopefully feel guilty and send you a new better card. Keep a copy of your letter and their reply. That way you have proof!
