The power supply is rated at that, meaning that it can draw that much if necessary. If you have no OD in a cube, for example, it is certainly going to use less power. But your power supply is the same! (300W on my old cube) Also, stating a wattage assumes a certain voltage, which is why the original poster gave a load in amps and a voltage. You get watts by multiplying volts*amps. .91*114, in this case. (note that this is 103.74, which is MUCH below the 300W that the cube's power supply can draw if needed) -- David Lemson (217) 244-1205 University of Illinois NeXT Campus Consultant / CCSO NeXT Lab System Admin Internet : lemson@uiuc.edu UUCP :...!uiucuxc!uiucux1!lemson NeXTMail accepted BITNET : LEMSON@UIUCVMD
