    The male tip is what I currently use on the 220 watt. The female is from the 330 watt. There are actually 2 white and 2 black wires that tie together onto the board with the green wire going to psid.

    Alright gotcha, this kinda confuses me tho, it seems it should be pretty much the same as the other PSU so what exacly is the difference? The white and black ones are power and ground, the green one is to charge the battery. I thought u had a different dell adapter, that's why I thought u'd have a centerpin :p

    The Dell supply has 3 terminals.

    Power
    Ground
    Sense

    Sense is used so the notebook can detect what supply is connected and its rating (based on the resistance of the line IIRC). I believe I remember people saying they tied this to ground to stop the supply from throttling (A small bias resistor was used rather than shorting it to ground I think, it's worth looking into). The main thing is to ensure it is not wired to live.

    Dual cables are used for ground and power to lower cable losses due the amps involved.

    Update on my PSU. I contacted Eurocom and they have the male adapter so that I can use my 330 watt psu. I looked everywhere on the net and couldn't find anything even remotely close to this. Thank you guys for the help! And thanks to @Eurocom Support for hooking me up with this elusive adapter cable. Below is a picture of the adapter.
