New SFF mod in the works that needs 200W of power with no standard PSU. I've got a 200 DC-DC power supply from Mini-box and they're biggest AC-DC brick at 110W but that isn't going to get it.
I need more pow-ah. There are 2 sources for 200W power bricks that I've found, the Dell DA-2 and the Xbox 360. The Dell DA-2 is giving me no love with the DC-DC power supply. Apparently it's a known problem over at the AVSforums. So that leaves the Xbox 360 and it's proprietary plug.
And we come to the subject of this post, I need that plug receptacle off the Xbox 360 motherboard (its a trashed one that I got off ebay).

Normally I'd wail on it with solder, a solder sucker, and my soldering iron cranked to "11" but my success has been so-so doing it that way. Given the problem that Langer had here (http://www.thebestcasescenario.com/forum/showthread.php?p=222264&highlight=desolder#post222264) , I didn't have high hopes.

It cost me about $65US including shipping.

The digital gauge on it says its putting out about between 800-900C cranked. Not sure if I buy that but I can't argue with results. It melts regular solder like ice. I mixed some regular solder on the back of the pins to get everything flowing.

A solder sucker and a few minutes later.

Not too bad for a first time. The plastic certainly took some heat. I mucked around with too much at first but its yards better than my soldering iron attempts.

Cleaned up the solder bridges

Now I need a bigger solder sucker. I'm going to try to pull all the caps etc off next. Hints & tips from you re-flow experts appreciated.
