Review on Tripp Lite P007-006 6ft Computer Power Cord - Heavy Duty, 15A, 14AWG, NEMA 5-15P to IEC-320-C13, Black by Teresa Carter

Not all cables are created equal, and that definitely applies to power cords. You don't NEED to just buy the cheapest cable you can find and assume they're all the same quality and range. the same properties so to speak. When looking for a power cord, the amperage is the most important factor in your selection. There are three general wire gauges (gauges): 14G wire for up to 15A, 16G wire for up to 10A, 18G wire for up to 5A. You can think of the current as the speed of water flow in a pipe. If a pipe can support a "flow rate" of 15A, it can certainly support 10A or anything under 15 (to some extent, of course). So it's perfectly fine to have a cable that supports more AMP than the device requires. Now you might be wondering which cable do I need. It depends on what you connect it to. For example, the EVGA power supply I'm using shows the AC input: 100-240VAC, 10A, 60/50Hz. Since the cable I bought was a 10ft 18GA version that supports 15A, I can see this Safe to use cable with my power supply. For a list price of $13.29 at the time, this was very reasonable. I highly recommend this cord.
