  1. Best answer
    Yes, the RM650i is a great-quality PSU and is certainly more than enough for a rig built around an i7-8700K + 1080Ti with enough headroom for efficiency and OC.

    GTX 1080 Ti @ ~250W TDP
    i7-8700K @ ~95W TDP
    Other basic components (SSD, HDD, Fans, RAM, MB, LEDs) @ less than 100W
    TOTAL ESTIMATED DRAW = Less than 450W

    Thanks for the answer, any information about 8700k's cooling needs? do you know if Cryorig H5 be enough?
  3. Depends on how much you would OC, but, from what I have seen, the 8700K gets pretty hot.

    From another review (using water cooling): https://www.gamespot.com/articles/intel-core-i7-8700k-cpu-review-a-performance-leap-/1100-6453799/#Temperatures
    As stated earlier in the methodology, we used the NZXT Kraken X62; an all-in-one liquid CPU cooler with a dual-fan 280mm radiator. However, the 8700K still got pretty hot. At idle, the CPU sat at a mild 32 degrees Celsius and went up to 78 degrees Celsius under load during our runs of X264. With using the 5.0GHz overclock profile, it reached 86 degrees Celsius under load in X264, which is considered higher than desirable.

    If you really prefer air coolers, you may want to consider beefier models such as the Noctua NH-D15 (though you may not like the "looks") or Thermalright Le Grand Macho. You may be able to hit ~4.8GHz, depending on the chip quality you would get.
