+1 to Akira and russianricks comments (lol sparky, haven't heard that one in years!) - I had extra power supplies from building PC's laying around that I used for years running cheap RA-Elco, mail and Internet ordered 12V fans, but once the last one finally kicked the bucket (all that humidity and salt spray in a stand, or even behind kills 'em) I just took someone's advice on here and got the $8 clip on Walmart cheapos.

Works great, and although I'll likely have to replace it every year, no power supply box with an octopus of wires to tuck/zip tie up/hide and no wiring, just clip and plug in the new one. pretty much everything else I do on my tank is ghetto-fab, afro engineered DIY though. Wish there were more cheap plug n play options for all the rest of it!]]> Tue, 11 Oct 2011 10:22:32 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=51636&PID=435345&title=fan-help#435345 http://www.utahreefs.com/forum/forum_posts.asp?TID=51636&PID=435244&title=fan-help#435244 Author: russianrick

If you don't mind saving some money, you can cannibalize some power supply from some other device.  You will find that most small electronics use 12v DC and so the only difference between most power supplies is the connector and how many amps and hertz are being put out by the power supply.  If you don't have any old power supplies laying about, you can go pick one up at your local Deseret Industries for a few dollars.

It is worth experimenting with the wiring, but as I recall from wiring my own fans, it is best to wire them up in parallel.  All you really have to do is clip the tip off the power supply, bare the wires, and start connecting things.

i know u dont want to hear this but if u ran 120v fans it wouldnt be an issue....but if u insist o running dc add all ur ma together and get a driver like 2ma abover ur total and it will last . if u load it to the max output it fail sooner because of heat and over work .... try looking at grainger.com for replacements and sizing requirments................what would i know im only a journeyman sparky :)

I think as long as you get a similar power supply you should be fine. I can come help you wire it up too if you need. I'm just about positive your fans are DC fans too.    ]]> Thu, 29 Sep 2011 20:57:07 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=51636&PID=434253&title=fan-help#434253 http://www.utahreefs.com/forum/forum_posts.asp?TID=51636&PID=434249&title=fan-help#434249 Author: Laird

"AC adaptor
input: 120v AC 60Hz .15A
Output: 12V DC 500ma"

Thats what it says on the power supply itself. The "AC Adaptor" line is 5 times the size as the info below it. Thats why I said it was AC. ]]> Thu, 29 Sep 2011 20:45:12 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=51636&PID=434249&title=fan-help#434249 http://www.utahreefs.com/forum/forum_posts.asp?TID=51636&PID=434237&title=fan-help#434237 Author: Mark Peterson

Now you tell us that the power output is DC. Maybe we need to back up and start from the beginning. Is that info off of the original power supply or is it a replacement that you recently purchased and found that it would not run the fans?

Here is everything that is on the old power supply. But I question if its what should be on the fans considering they all broke...

AC adaptor
