ATX Main Power adapter?

[yukitrance]

I'm currently building a PC for a friend of mine. What I'm doing for him is taking the parts from his old pre-built out of the case and putting it in a new case and putting a new psu and graphics card. I've come at a halt when installing the power supply. The ATX Main power port on the motherboard is significantly smaller than the power supply's. Is there some kind of adapter I can use or am I just screwed on it?

What motherboard was it?

You don't need an adapter. Looking closely at that photo, the new main power connector is a "20+4 pin" connector, so you should be able to shift things around a bit to get the extra 4 pins out of the way.

No, he has a fair question. Both connectors have 24-pins (I counted).

No I don't know the answer.

EDIT: I think he could be looking for something like this

Looks like an older proprietary from a DELL or Compaq, they also used some proprietary PSUs (now that I think of it HP did in the past also)

Agreed that is a proprietary power supply it won't work with a standard ATX board.

I had a hp Z400 workstation that was very similar.

Thanks I just found some of those. The only thing is is that I've only been able to find ones that you lose the extra detachable 4 pins from the regular atx power. Will this become an issue for trying to power a gtx 660 in the system?

Motherboard is: ASUS M2N61-AR

Based on this article page:

I'd say that using an adapter with only 20 of the 24 pins wired is risky. It says that some boards have a molex and/or sata power connector in case the psu only has a 20-pin connector, but I don't see one in this picture of the board you listed:
