I am building a power supply for my shop. 0-24vdc/2a, +/-15vdc/1a, +5vdc/2a, +3.3vdc/2a. The 24v and 15v outputs will be fed from isolated voltage converters to keep them independent.
Rather than spend a ton on an expensive boat anchor transformer I would like to use an AT/ATX power supply to feed the voltage isolaters with 12v, and use the 5 and 3.3 outputs direct but thru current limiters.
I can get new supplies for $11, used ones for $5, and maybe even a free one from my buddies geek son. Are there any sucker traps with this plan? Any suggestions?
