Ok, I hooked up 2 13.8 volt power supplies I have in series to get an ouput of about 24 volts after lowering the voltage on each a bit. I ordered a drift 0.8 172 watt peltier and hooked it up today, and when I got into the bios, the temps were a little over room temperature, much worse than the 156 watt peltier I was using before. So I got my multimeter and found that when I hooked up the peltier to the power supplies, the voltage dropped from 24 volts to about 10.5 volts. Is there any way to stop this from happening or is there just no way to use these power supplies in series?
