[SOLVED] How can I use molex or sata to power a amplifier board?

[johnphilips]

Hi everyone. I would like to power an amplifier board, such as the ones from amazon( example https://www.amazon.com/EBTOOLS-Digital-Amplifier-DC12-24V-TPA3116D2/dp/B0828Z4Y7Z ), using the sata or molex cable from my psu. (or maybe both at the same time, if possible). By doing this, I could avoid using a 12v psu only for the amplifier, I think, but I don't know where to start. Any ideas?

Well.. that particular amp, for example, accepts 12 to 24V input. So you would cut the end off of a Molex or SATA cable, take the 12V and ground wires, and screw them down into the terminals.

But can I use both? Because there is a molex and a sata, 24v would provide more power to the speaker or make me go stereo. Thanks in advance

That's not how power supplies work. All of the +12V come from the same source. If you take +12V from two connectors, you still have 12V.

Also, voltage is not power. When you double the voltage, you don't double the power. The power is the same, just the input current is lower.
