What I'd like to do as I move forward, instead of buying lots and lots of PC based Power Supplies, I'd like to buy larger power supplies (maybe units that can provide 5,000 watts of 12 volts - or something...) and connect multiple miners to one larger PSU. Except, I have little to no knowledge / experience with large Power Supplies.
5000w of 12v? Even if you can do that, are you sure you can cool 5kw in a small area? A lot of home miners have to spread their miners around the home to avoid turning one room into an EasyBake oven.
