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.
