15.7 watts isn't much...  I'm no authority on STs, but it sounds like your
close to the edge there.  Keep a voltmeter handy when you upgrade, and if
the voltages drop much when you add the memory (and the machine acts flakey)
you need a larger PS.  Which should be easy to find...  (jameco and a few
other paarts houses have odd Power Supplies in abundance! Just cut off
the cord that comes with it, and replace it with your cord...)
