I got a free 2009 mac mini and it needs 110w 18.5v and 6A. I have a psu from a g4 that has 85w 18.5v and 4.6A. Now im aware thats not the same so dont tell me that. My question is that i have no clue if it works and i dont want to buy a psu for it to find out that it doesnt work. So can i use the one for the g4 to test it? I figure as long as it doesnt work to hard it wont be a problem. If its not even possible is there a way i could power it using an old laptop power adapter or an old computer psu? Thanks to anyone who can give me useful information!
@cam2363 yes you can use it for testing purposes. You would not want to use it for everyday use since it (the PSU) could get to hot when the Mac Mini starts to pull more amperage from your supply.
If they have the same pins and port it should be fine.
