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?

8Ω is pretty low impedance. By comparison, the Sony MDR7506 is 63Ω, and they work just fine with the amp built into my mobo at only 10%.

Are you sure?

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
