PC Power Supplies used for AC-DC Convertor

[pilot_bell777]

Found a way to take a PC Power Supply and connect the pins correctly to use the power supply as an AC to DC convertor to run multiple computer fans without having to buy multiple adaptors or use multiple plugs and you don't have to wire the fans differently either because they just plug into the power supply.


Figure out what type of pwer supply you have and look up its DC pin out on the web. Tons of stuff, I found mine pretty easy. Then you just jump the PSON to a black ground and your done and your power supply will stay on without being connected to a mother board or anything else for that matter.

:lol

So now I have a cheap (free, got it from work) AC-DC convertor that will run all my fans from one plug! YEA!!!!

LOL......

My plan is to extend the wires and then shrink wrap them with rubber shrink wrap to keep them from being exposed and protect them and then have the long wires go far away from the tank and keep the power supply away from the tank and water.

I though about already! LOL

You can always come across a old computer case and leave the powersupply inside it. Run the wires out, to the fans through the back. Can even go as far as mounting your controllers on the outside of it (ie osmolator display) or rig it up to put power strips inside to 'hide them', and just have the cords coming through the backside. ;)

I wonder if this would run the DIY moonlights (LED) too??

[pilot_bell777]

NO, NO, NO...I was talking about shrink wrapping the WIRES only! LOL so the splices were not exposed and then running the power supply far away from the computer! LOL

I was thinking that also. Rebuild an old pc and use it for tank mgmt and such.

yeah you can actually program something to work of the Serial or USB port like a night/ day cycle with LED's.... Hmmm that may be an interesting task. I have an old laptop that needs a reformat and this would be an excellent program to dittle around with. Other then that you could actually run some of the LEDs directly off a motherboard, or some cases. you have 2 sets of wires basically in the cases the yellows and red are the ones you care about. I think the yellows are 5 volts and the reds are 12v. So you can plan accordingly.
