Naah, I haven't bothered opening it up. I wanted something simple and cheap. A regular ATX is too much work compared to this PSU. I will ask at work if boosting the voltage is even feasible with this PSU. I have no schematic of what the other pins do. I was pulling 25A last nite out of the PSU and the charger stated 12.8V@25A. When I get a few more, I'll open one up.
