Which power supply will max out first depends entirely on what it's exact output voltage is set at. Meaning if the little one is producing a few tenths of a volt more, it will exceed it's current rating first. Not only should the supplies be matched in amps, there voltage regulators should be set at precisely the same voltage.

Remember to look at the constant amperage reading which on the 12 amp supply is 10 amps constant and 12 amp surge I believe. The 7amp would be 5 amp constant and 7 amp surge or close on constant.
The surge just mean it will under a heavier load max out at the surge number but not recommended to tax the supplies full time at surge limits a 12 and a 7 amp supply are capable of 15 amps contstant and about 19 amps surge but again dont run it at surge levels to much or it will nmot las long.
In example if you have a corvette that will do 160 MPH and everyday you drove it at 160mph the engine wouldnt last very long

What is under the heat shrink tubing on the cables connecting the two supplies ? Diodes, maybe ? Or...?
I'm assuming it's something similar to this:
Snap-Together Ferrite Choke Core - RadioShack.com
But with that guy, who the hell knows.
Very possible, they do have that rounded look to them. Hard to tell on my netbook. I'm betting they aren't though...who knows.
Personally, I wouldn't try it with mismatched supplies. Limiting diodes and (as Shockwave mentioned) making sure the output voltage from both supplies is the same is critical in making the supplies work together. Some of the Astron supplies have the needed circuitry already built into them. They are identified by the addition of a 'parallel' output terminal on the back of them.
Didn't you already have an account here and you threw a fit about wanting to be removed, not coming back, etc? I'm not thinking so clearly today but that's what I'm remembering.
