All UP and most DP LGA4189 board support up to 270W TDP. even a 300W OEM runs on a X12SPL i.e. but can be rejected by coming BIOS revisions if supermicro wants.If it's anything like Skylake, you'll need a board capable of booting high-power CPUs, or reflash the VRM controller over SPI to raise the power limit.
'C' suffix parts (2nd gen and up)Not sure if it'll be distributed to OEMs or Retail,
