Disadvantages to using longer power cables for networking equipment?

I'm setting up a Catalyst 9300 stack (2 switches) that use two 350WAC PSUs per switch. The supplied power cables are 18 AWG.

I need to plug them into PDUs that are about 11 feet away from where they are racked. Will I face any noticeable electrical resistance by using 12ft 18 AWG power cables to these switches? Maybe go with a lower AWG like 14 AWG?
