My MSI MAG Z790 motherboard supports rear channel speakers.
If I were to mount a pair of speakers behind me, that would require approximately 15 feet (4.5 meters) of speaker wire from my PC to the speakers. Do I have to worry about the AUX port’s power output if I were to use 18 or 16 gauge speaker wire?
I'm pretty confident but not 100% sure, I'm on my phone and only skimmed the manual.
Impedance isn't the issue here, headphones are completely different - their tiny speakers need significantly less power to drive them. I don't think the motherboard is capable of moving the cones in the speakers OP linked
The giveaway here is the inputs - your headphones have an aux (or 1/4"?) input and these speakers have speaker wire inputs
I mean, you can always solder a 1/8" stereo connector onto those wires, but the point about wattage isn't something to be ignored, and I forgot that.
Thanks!
I did some wacky cable conversions when I worked in the field but it was usually just to extend line level
Analog audio is fun lol
