Comment: Fixed command for 230w

Intro

Quick look at typical 2000W mATX power supplies input/output spec:

...

  • 4x 250W and a 250W CPU (AMD Threadripper) = 1250W

  • 4x 350W and a 280W CPU (AMD Threadripper Pro) = 1680W

NVIDIA added dynamic clocking and GPU Clock booster features that allows your GPU’s power consumption to go above and beyond what is advertised, since the GTX 600 series . This feature has been improving through GTX10xx series to the RTX30xx series we use today, and it only gets worse with the next generation of RTX40xx GPU’s that we’ll see in systems soon enough. Although this GPU clock boost sounds great on paper, you will ultimately be limited by power and run into issues with your system that could be frustrating to troubleshoot.

...

1200W is pretty exact on the example PSU limitations for 110V I stated above, so you should definitely start here and adjust the wattage up or down depending on what works for you or your building’s outlets/PDU’s.
