ok, so I feel like I went to basic in my wire explanation, and my intention was lost as a result. so to further explain this issue that I feel you might run into when trying to over clock that threadripper CPU. I will use the CPU power connector as the example, keep in mind that the video card power wire, may do the same thing if the video card is overclocked as well.
ok so you have your stock power wires and the CPU power wire is a 8 pin wire connector. it has four power wires, and four ground wires. we know that each 20AWG wire has a 6amp at 12volt safety limit, the power supply detects this through the impedance of the wire. as the amperage on the wire increases, the wire begins to heat up, that heat creates a higher impedance when the impedance reaches a certain point the power supply will shut that lead down. so in general use, the power supply, will shut down that lead when it reaches 24amps total. even though my power supply is rated at 30amps per lead, the only way it will actually go that high, is if my home is at 16C. my home is at 28C most of the year, so I only get 20amps, before the power supply will shut my lead down. if I upgraded all the power supply wires to 16AWG wire, the power supply would deliver 48amps to the lead, before it would shut it down. the reason for this is because, the impedance on a 16AWG wire will be a lot lower, than the impedance of a 20AWG wire, at the same amperage. meaning that my once 30amp regulated power supply, is now a 48amp regulated power supply, because I am using larger wire.
understand for me this is a hobby, I am to old to race cars anymore, so I race my computers. at some point I push all my systems to their absolute limits. as a result of this, I have had to make several upgrades to my hardware, to handle my desire to push things. when I run into issues, I try my best to diagnose the problem, and correct it. my elaborate water cooling configurations, are also a result of me altering things, to make them function the way I want, or need them to. so yes, I take things to the extreme, because of this, I see at lot of issues, that the normal user would never run into.
