Alright, guys, I am looking into building very powerful and very cheap supplies. I currently have two dell 700 watt 2850 server power supplies (no internal pots for voltage ) and I am looking at building myself a 120 amp 12 volt power supply out of them. Now, these are originally run with redundancy in the servers, so I want to run them in parallel. They have a +12v current share which I am fairly certain is the communications between the two supplies to equalize the load for redundancy. So, if I connect each of the psu's +12v share to each other they should share the load (based on the name) and connected in parallel should give me 120 amps (psu's are heavily underrated in the server world) To connect them I am planning on using the 2 12awg outputs each psu has and connect them to a power distribution block. (buss bar) I am thinking that stainless steel bolts, washers ring terminals and nuts should be enough to transfer the current. I use this method for speaker terminals in high powered car audio (15,000 watts on the subwoofers) So, 1200-1500 (theoretical) watts shouldn't be a problem. Now, is my plan bone-headed or am I thinking clearly (finals are awful) because, I am hoping to be able to power all of my friends chargers, or all of my local track from one system instead of having those 16 awg ungrounded 20 year old extension cords that they use. Any input is gladly accepted, along with negative feedback.
I would recommend getting HEAVY duty input wires for the power supplies. My dad works for ATT's datacenters and grabbed 2 unused 15 amp 240volt server cords for me. I have heard of computer cables melting and shorting out when used with smaller supplies.
