Apple lists the QS and the QS2002 both at: "Maximum continuous power: 360W" (ref. http://support.apple.com/specs/powermac/Power_Mac_G4_Quicksilver.html and http://support.apple.com/specs/powermac/Power_Mac_G4_Quicksilver_2002.html ) We Love Macs shows the QS and QS2002 both using power supply p/ns 661-2513 or 661-2514: http://www.welovemacs.com/g4sedu1gq20p.html http://us.st11.yimg.com/us.st.yimg.com/I/lovemacs_1915_18473636 and http://www.welovemacs.com/apg473qpcpos.html http://us.st11.yimg.com/us.st.yimg.com/I/lovemacs_1915_32546064 -- Rich
