I recently purchased a MegaWatt S-700-12 50 amp switching power supply. As I outlined in this thread, the fan is too loud for my shack. The supply is new in the box as I received it new from MegaWatt on February 3, 2017. I had it powered up long to set the output to 14V and while doing that I learned the fan is too loud for my shack environment. I powered it up the next day to make the sound level measurements listed in the thread above. I am asking $110 for the supply shipped to the continental US. Payment details will be agreed upon later.
