In the PC universe, we'd get a bigger power supply. That hard drive isn't small; you could externally power it from a PC supply (I'm only half-joking). Alternately, you could comb the power-supply catalogues for a comparable supply of similar form factor. Power supplies are the great undiscovered gotcha in the Mac. Over in PC-land, we all got bit early and often by this one; even your 250-watt supply has no overvoltage protection, so it's *SNAP* everytime a component cooks. Unless you spend $180 on a PC-Cool or similar U.S. supply. Sorry, don't think they've gotten to Macses yet. Ask Sony--they make most of the Mac supplies. Alex
