My motherboard has a non standard 24 PIN power connector
My computer is a HP Pavilion s7730 with a Asus MOCA-AR (OEM) motherboard (can't select it in the model list...). I need to use the computer in a car, so i need to adjust the power supply. For use in my car i will use:
http://www.mini-box.com/M2-ATX-160w-...8&category=101
The problem is that this device has a 20 pin, and the Asus MOCA-AR a 24 pin power connector. A normal adapter (from 20 to 24 pin) like this:
http://www.tigerdirect.com/applicati...751&CatId=1107
won't work, because the 24 pin connector is much too large for my motherboard. I have made a picture of the power connector from HP Pavilion power supply (black one) and my 20 PIN (white) connector.

Any change to find an adapter for this (or make one by myself?)
Kind regards,
Marcel

The short answer is make it yourself or use a different MB.
HP, Dell and others sometimes use non-standard PS parts. It may actually use different voltages and or pin outs.
Be very careful as mixing up the wires can break your MB.
Use a meter to measure the voltage of each wire before attempting to use an adapter or different PS.

you can still plug 24 pin power from psu to a 20 pin port, works on most motherboards ! just the 4 extra pins will OVERLAP the plug, if theres room on the edge, it'll work.

This statement assumes the MB uses a standard pin out, this is not always true for Dell or HP.
Use a meter to make sure before you let the smoke out.

Thanks for your answers.. To buy a new motherboard. a jut bought this computer a few days ago:-(
Ok, i'll make it myself and will measure before i act. But i still have to get the right connector (the black one). Does anyone of you recognize ths connector? It is much smaller then the regular 24 pin atx connectors....

I'm interested in your solution or what the pinout of the connector is.
The tech at HP gave me the following for a 20 pin based on the motherboard, but I don't believe he knew what he was talking about:
ATX Power Connector
Pin Signal Name Pin Signal Name
1 +3.3 V 11 +3.3 V
2 +3.3 V 12 -12 V
3 Ground 13 Ground
4 +5 V 14 PW_ON
5 Ground 15 Ground
6 +5 V 16 Ground
7 Ground 17 Ground
8 PWRGD (Power Good) 18 -5 V
9 +5 VSB (Standby for real-time clock) 19 +5 V
10 +12 V 20 +5 V

No, the motherboard as a 24 pin connector, which uses exactly the same pinout as ä regular connector.
Anyway, i did loose my patience. I have cut the wires, and soldered it directly on a regular connector....

So it really was a regular ATX connector, but they shrunk it down?

I have the same computer. You have a nano-atx motherboard. I'm setting my computer as we speak. Here's the link got the adapter. I still haven't ordered it but it should do the job.

Hi,
I have the same board, and I just want to say that I bought the above adaptor and it DOESN'T do the job. They are of different size.
So the quest continues...

I had the same problem. Two ways to solve
1) buy the hp power supply for ~$55
2) buy a 24pin atx extender cable ~$5 + Time + Effort
You get this....not very pretty, but it works...glue gunned it to get it to stay

Some electrical tape or shrinkwrap or braided sleeving or split loom will pretty that up substantially.
Hell, even bundling the individual wires with zip-ties would improve aesthetics.
Now that you have the function, go for some form.

Hi all,
Just want to say that I managed to get some of these 24-pin connector, with socket pins.
If anyone needs help & wants one I can post it for the price I paid for them, which is £3.25. I will have 9 left. They are currently being sent to me from Hong Kong.
Thanks.

Any pictures? Are the connectors and pins already crimped?
