It is no snake oil after all - power cords do affect the sound quality. While it may be questionable whether it "improves" the sound, what power cables actually do is get rid of EMI/RFI pollution and remove other problems associated with standard power cables, allowing your system to perform better.
Regardless, do audiophile power cords make a difference?
For example, an "audiophile" cable can make bass notes even better, typically "more powerful". The high end might sound "sweeter" and "more extended". Well, as you can see, at a typical 1W output which is not an unusual, normal playback level for home systems, there's no difference between the two cables.
On top of, does it matter what power cord I use? If you are referring to the 110 VAC power cord there is no problem as to which cord you use. However, the cables that connect from the PSU to the motherboard, devices, graphics card, etc. are not inter-changeable from one brand to another.
Still, are expensive power cables worth it?
An expensive cable might sound worse on your system than cheap cable. Or it might sound better. The important thing to remember is that even if it does sound better, it's such a minuscule improvement that pretty much anything else you can do will have a greater effect on the sound.
Are all 3 prong power cords the same?
Yes.... they are all IEC cables and they are interchangeable. Just makes sure that stuff like power amps that draw lot's of current have the ones with heavier gauge wire in them.

With amps, the sound, as opposed to notes, is the first thing to go. A great amp strips away the artifice of sound reproduction and lets more of the music shine through. Vacuum tube amplifiers measure and sound different, some say better, some say worse than solid-state amps, but again they both play the same notes.
Power Cord Shielding Shielding of power cables serves no useful purpose. Shielding will add significant capacitance to the cable with minimal positive benefit.
Electrical cables work by providing a low resistance path for the current to flow through. Electrical cables consist of a core of metal wire offering good conductivity such as copper or aluminium, along with other material layers including insulation, tapes, screens, armouring for mechanical protection, and sheathing.
Electromagnetic interference (EMI) is caused when the flux lines of a strong magnetic field produced by a power conductor cut other nearby conductors and cause induced voltages to appear across them. When signal cables are involved in the EMI process, this causes a noise in signal circuits.
Again, these are standard cables. As Bruce stated, the power cords are universal. Even some monitors (generally older CRT models with detachable cords) and some printers use the same type of cords.
A higher voltage than a device is designed for will most likely blow up some components, but amperage is derived from how much current is actually drawn, based on the device's resistance, so having “too much” is not a problem and will do no harm.
There are two ends to a power supply cable: The device-side and the PSU-side. The device-side of all PC cables is standardized. ATX 24-pin, EPS12V, PCI-e to the GPU, SATA—the wiring is known, and it doesn't change. What isn't standardized, however, is the layout of the PSU-side modular cable headers.
The Ethernet cable is [also] a big problem. It runs long and can pick up low-frequency noise which cannot be filtered out. This noise will introduce jitter at low frequencies which no PLL circuit can get rid of and it will affect sound quality a lot.
Both HDMI and optical cables pass the digital audio from one device to another. ... The major difference is that HDMI cables can pass higher resolution audio which includes formats found on Blu-ray like Dolby TrueHD and DTS HD Master audio. Fiber optic cables won't be able to transmit these high-res sound formats.
Only if they're broken, or unusually susceptible to noise. Cables can do nothing to "increase" sound quality, but in some rare cases they can be designed so poorly that they pick up noise, or make poor connections.
All three-prong plugs must be connected to electrical receptacles that can receive a three-pronged plug. ... When you plug in a three-pronged plug, that third prong is providing an alternate pathway for electricity in the event of a fault. If you cut the third prong off of a plug, you defeat the safety feature.
Any cable will work. A 1,000W power supply (80% efficient) will pull about 10 amps at full load. That's well within the specs of any of those cables. Some compaines do sell heavier duty cables, with larger wires in them, but there's no need in this case.
IEC C14 to C13 cords are the most popular type of power cord used to power equipment in a data center server rack. Sometimes referred to as Jumper Cords, C14 to C13 cords are used to connect server and network equipment power supplies to a PDU or power strip.
