Review on High-Quality 3ft 14 AWG Computer Power Cord - C19 to C20 - Heavy Duty 14 AWG Power Cable - Extension Cord from IEC 320 C19 to IEC 320 C20 by StarTech.com by Jennings Ford

These computer power cords are very high quality. The cables are extremely thick and strong, and the connectors are strong and sturdy. This has a C19 connector on one end and a C20 connector on the other. This cord comes in handy as an extension cord, giving you 6 feet of wiggle room when needed, depending on device placement. The company advertises a lifetime guarantee. I have not yet claimed this guarantee, I am pleased to report. But if it matters, I'll post an update. This cable appears to be of high quality and I expect it to last a long time.
