Does power cord for desktop PC matter?

I recently dabbled into power cords from the basic ones and the improvements have been tremendous. I use my desktop as a source, not ideal but it's where I do most of my music discovery and this is my preferred method. 

I'd like to ask you fellas with experience, do power cords for desktop matter for the sound?

I plan to get a very nice (affordable) active USB cable at a later date for the PC. I just want to keep it simple and deal with power cables at this time. Thanks y'all.


Tried it, no difference on my Dell XPS 8950 with 1000 watt power supply. 

Power cords and power conditioners are useful in both giving clean power to equipment but also to dissipate the noise rejected by the equipment it’s attached to and avoid its contamination to other equipments’ power supplies. In the case of a PC, the benefits come probably more from the second category rather than the first if I had to guess. But who knows? Doesn’t hurt to try using a power cord you already own or if you get one loaned to you.
