which is the power cord for mac mini 1176

This is one of the early Intel powered Mac minis, these used the 110W power supply rather than the 85W power supply that came with the PowerPC based Mac minis. I don’t see any of these power supply on iFixit but a quick search found two options through Powerbook Medic and Other World Computing… Powerbook Medic - $40 110W power adapter Other World Computing - $46 110W power adapter For what it’s worth the Apple service part number is 661-6386. Hope that helps!
