I was more worried about the current requirements. I don't have
my IIgs hardware reference any more, but according to the IIe
technical reference manual all cards share:

 +5V : 500mA
 -5V : 200mA
+12V : 200mA
-12V : 200mA

But, off the top of my head, I don't know how that translates
to 585mA @ 1.3V + 165mA @ 3.3V (I forgot that second part in
the first post)
