Where to get an AC to Molex adapter?

[miniyazz]

I'm after a power adapter that plugs into a normal wall socket and provides at least 7.5A, preferably 10A, to a molex connector (presumably at 12V and 5V).
Reason is I'm wanting to power 4 HDDs external to the PC. I already have a 2.5A adapter that can power one normal 3.5" HDD or two 'green' 3.5" HDDs, so hopefully 7.5A should be enough.

The most I've found is a power adapter providing 5A.

Any help most appreciated.

Could you just not use a normal power supply and slave it to your system , or connect the green and a black wires to make it power up. ( you would need to check which wires are specific to the supply being used before following this advice)

That's definitely an option, as I do have a spare PSU knocking around. Ideally I'm hoping for something a little more portable though, and using a 600W PSU to power a few HDDs seems a little overkill
