Load regulation is tight at 12V, which matters most, but loose on the rest rails.

  1. My 9060XT 16GB graphics card has a typical board power (TBP) of 160W to 182W, which requires 13.3A to 15.2A of current. The card uses a 6+2 pin PCIe connector (600mm), but many power supplies use a mix of 16AWG and 18AWG wires for these connectors. Will the 18AWG wires be able to safely handle that much current?
