Tripp Lite Heavy Duty Computer Power Extension Cable PDU Cord 15A 14 AWG C14 to C13 Blue, 1.83 m (P005-006-ABL)

I've been using it for over 6 months between a UPS and a 1000W PSU. The cable is quite thick, does not get warm and it's not stiff, making it easy to route. I like that it's red, as it stands out from the jumble of cables behind my desk and I can easily tell it apart from the others.I was a bit worried at first because the connectors themselves seem like they are made of very brittle plastic, but so far no issues.
