Manufacturer description
The StarTech.com PXT10120 is a 20ft (6m) NEMA 5-15P to IEC 60320 C13 power cord built to replace the short stock cable that shipped with your PC, monitor, or laser printer. Twenty feet of reach means you can park a tower under a desk on the far wall, or feed a printer in the corner, without a surge strip acting as an extension cord. The 18AWG cable uses 100% copper 3-conductor wire rated to carry 125V at 10A, with a PVC SVT jacket measuring 0.25in (6.3mm) in diameter and a VW-1 fire rating. Both ends use fully molded strain relief connectors, and the cord is UL listed under UL62 and UL817…

Frequently Asked Questions
Will this power cord work with my desktop PC power supply?
Yes, if your PSU uses the standard IEC 60320 C13 inlet found on most desktop computers. StarTech.com also lists compatibility with many monitors, scanners, and printers. The wall end is a NEMA 5-15P for North American grounded outlets.
Is 18AWG thick enough to run a gaming PC at 20 feet?
The cord is rated to carry 125V at 10A, which is 1250W at the plug. That covers typical desktop and monitor loads, but check your power supply's rated draw against the 10A ceiling before using it on a high-wattage build.
Is this cord UL listed?
Yes. The PXT10120 is UL listed under UL62 and UL817, uses 3-conductor 100% copper wire, and carries a VW-1 fire rating. The jacket is SVT-rated PVC.
What is the warranty on this StarTech.com power cord?
StarTech.com backs this cord for life and includes free 24/5 multi-lingual technical assistance. Check the product listing for current warranty terms and claim details.
Can I use this outdoors or in an unheated garage?
It is not rated for that. The specified temperature range is 37F to 140F (3C to 60C) and the PVC jacket is intended for workstation and home office use, so keep it in conditioned indoor spaces.
