Microsoft HD-DVD player psu

I've been looking at getting a psu for the Xbox 360 HD-DVD addon.
Problem is I can see 2 different microsoft psu model numbers and I'm not sure why (both are available as 100-240v input afaik).

So there's:

PSC24W-120
12v 2.0A

and

STD-1225M
12v 2.5A


Ordinarily I would just simply adapt a psu close to spec for a task like this, but the HD-DVD drive itself has an unusual DC socket which I don't have the correct plug (barrel and pin) for at all.
I do have a 12v 2.0A DC adapter here, I guess I could open up the HD-DVD player to desolder the odd DC socket and solder in a standard type but I'd rather not tbh.




Edit:
I think I figured out what the odd DC plug is.
EIAJ-04 (think this is a Japanese designation but I'm not sure).
Also, there might be a Lumberg part number (maybe 1636 04).

Anyway, specs should be outside diameter 5.5mm, inside diameter 3.3mm, pin diameter 1mm, barrel length 9.5mm.
Rated for 10.5-13.5v.

It kinda looks like plugs you see on some laptop psu's but smaller.
