The newer processors may actually use less power in some cases, but if you are running extra drives and add-in cards, having extra power would be nice. One's options are not to easy on that account however... MacPro online replacement AGP G4 237 watt power supply for $97 (and you can get them cheaper on ebay) http://www.macproonline.com/Shop/Control/Product/fp/SFV/32645/vpid/5636650/vpcsid/0/rid/129150 An article from Accelerate your Mac that discusses pin out issues between the original AGP g4s power supply and the more common (and cheaper) ATX power supplies. The ATX power supplies will fit, but matching the pins takes some work I did see once that you could buy an adaptor to ease this process, but I didn't go this route personally. http://www.xlr8yourmac.com/systems/ATX_G4_AGP_conversion/G4_AGP_to_ATX_case_pg2.htm Good luck with the upgrade - Jeff
