My first pc was some hp tower from a college? that i got for free, at the time i didn't really understand too much about pc's and bought a 660 ti, at which point i realized my PSU didn't have the proper connectors or enough power. I then bought a 400 watt micro atx PSU and some adapter to connect 2 PSU to each other from china, and duct taped it on top of the 5.5 inch disk drive. Didn't break and worked for a few years. It had a legacy intel i5 -660 and 12 gigs of ddr3 ram
