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?

        Those are passive speakers that won’t work without an amplifier. You need some PC speakers with an aux input

        You can’t go from 1/8" to 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

          Can’t believe I forgot to include that tidbit, that they’re passive speakers.

          Isn’t the motherboard itself the amplifier?

            Unfortunately not, the motherboard only has a preamp. Those ports output a line level signal and the speakers are expecting speaker level which is post-amplification which is a MUCH stronger so it will be extremely quiet - if not completely silent

            You can buy a cheap 2ch amp but I think you’d be better off with different speakers. It wouldn’t be a bad idea to get a second set of whatever you’re using for the front speakers to match the sound profile
