Connect PC power supply 12v1 and 12v2 together?
I have a PC power supply that I want to use to power a music system. I need 400W, which is why I need to connect 12V1 and 12V2 on the power supply together. I unscrewed the power supply and saw that, as expected, both 12V outputs feed into one source, but each output has a series resistor. Wouldn't the total resistance be halved if I soldered both outputs together? I think I should remove one. What do you think? Will the resistor break, or will I damage the power supply?

Hi.
Does the 12V output have 10A?
You need +12V and -12V for the amplifier. I could imagine that this is going with 2 separate power supplies if they don’t share a mass. If they have the same mass on minus, it doesn’t work.
On the Selundary side of a power supply, I wouldn’t sit around.
thanks for your answer, why do you think it doesn’t work with the same? I know that two different power supplies cannot be simply combined because of the slightly different voltages and frequencies of the control. LG
Hi, they would have both connected their minus to the housing which is grounded, then you would immediately connect the plus from one to the minus from the other to have a series connection that shortens a power supply immediately.
Do music systems not have plugs that you put in the socket? I would strongly recommend you not screw around a power supply or even solder around! This is life-threatening.
Describe your music system and the project, maybe there is a safe solution for it.
The safe solution is to buy a power supply. LG
