I have a question about connecting 12v fans. Why do I need to purchase a pc computer power supply to power the pc fans? I was doing some probing around the internet and stumbled upon 12v dv transformer. http://www.hometech.com/power/powersup.html#XA-781RG (see link)
I am trying to get power to three fans Assuming I cut the connecter/plug off and splice all the fan wires together; does anybody think this would work. Can you think of any reason why this way won’t work? I just want to make sure it will work and I won’t burn the house down. Any info anyone can shed on this would be great.
Thanks
JoeI think there were two good reasons to go with a PC pwr supply. One, the connectors on both work easily together and second, it’s what was handy.
In my case, the latter was definitely the case, but I can’t see any reason you couldn’t use the power supply shown in that link as well.
I know this is quite an old post, but just in case someone wanders along in here looking for answers…
You can buy a 12v dc power supply on Amazon along with a splitter and even additional extension wires to power multiple fans with one power supply. Here are a few links…
