Anyone else have the issue of a computer power supply not turning on because it's too cold? I'm trying tubing for the first time and have a shurflo set up with a temperature controller and it wouldn't turn on. I heated the pump and power supply with a blow dryer and it started. I'm trying a 40W lightbulb now to see if it will keep it warm enough. If that doesn't work, I'm not sure what to do. I don't have another power supply to try. Any suggestions? The whole setup is in a tote box with a lid, not out in the open.
