I build LED strip lights using old florescent shop lights metal reflectors and used as the heat sink solution for the strip stick on LED light.
Total of the LED strip was about 6.5 meters and I purchased a 450 watt computer power supply to run them. I wired so they would run on 12 volts.
Everything was running fine for about 2 weeks. However the other day, when I tried to turn them on, they would turn on for about 10 seconds and go off. I checked if the PS was dead, but I could see the fan moving and sound of it.
I tested the LED strips and made sure some wiring did not touch each other + & -. Today I tried again and light just blinked and that was it. But this time it looks like the power supply died as well!
I have very limited knowledge of testing it, but would love to pick few brains here if there is something I could test or perhaps fix. Power supply was purchased brand new, 450 watts, it's Kentex brand.
Thank you so much for your help.
