Hi Hooterville,

Sorry if you thought i was implying not to do it, i just meant you need to be careful.

I do know on certain ATX power supplies you can join the sensing leads and have it running constant without any problems as it is just the same as running a PC 24/7 so it will eventually burn itself out.

We use these power supplys all the time as benchtop supplies and they are actually really useful as they have multiple 5v and 12v feeds.

As a thought if you have an old Intel i core CPU heatsink this will work with the Resistor to cool it.

Hope this clears things up.

Jay
