Power supply part number discrepancy

Hi,

I was given an iMac Intel 20" EMC 2210 2.4GHz because it is not powering up. So I opened up the machine and noticed power supply has burnt stain on it. And there is no LED lit on system board.

At this point, it is obviously the power supply that needs to be replaced.

But from the guide provided on this website, the Apple Part #: 661-4670.

I see a different Part # 614-0415 on the actual sticker of the power supply. Along with Model#:HP-N17000XC

And the picture shown on the part listing on this website doesn't look like the actual power supply that I have.

I'm about to place an order but a bit confused.

Could anyone clarify my confusion?

Thank you.

Thanks.
