Absolutely! The power budget for the A500's expansion bus is 300 mA of
+5 volts and 50 mA of +12 volts. The Supra far exceeds this spec. A
friend had the same setup, and his system was completely unreliable
until he added a seperate power supply for the Supra.

(This is where I usually say something like "Supra should be put in
stocks, and publicly flogged for selling an unpowered hard drive & RAM
expansion for the A500." but I've said that several times before, so I
won't bother.)
