Hello guys. I run my 7820X cpu at 4.7Ghz (Water), also overclocked my 1080Ti KINGPiN card to the best performance (Air).
My question is the 1x8 power connector and the 24pin ATX connector enough to run the system or do i need to plug the second 8x power cable.
Because sometimes it freeze out if i use my computer close to maximum.
But if i use it on half performance it is okay with it.
Does it mean, didnt get enough power my system or is it an another problem?

    Run Both 8-pin EPS / CPU for OC stability
     
    How many Watts does your UPS or other device show your pulling ?
     
    If the PSU is having any issues ... then that is also some thing to check -->  after connecting both 8-pin & determining how many watts your pulling
     
    your UPS (if you have one) could be too small
     
    get a kill-o-watt type device if your UPS does not have a display
     
    notice I keep saying UPS ---> OC without stable power is never stable

    On Page 18 of your Motherboard Manual it says "For optimal performance with Intel® Core X-series i9 Skylake-X processors, BOTH (8-pin EPS/CPU) connectors must be plugged in with CPU power cables."
     
    There is also a Supplemental PCI-E 6 Pin Power Connector at the bottom-left of that board..It provides additional power to the PCI-E slots above and beyond what they normally get through the 24-pin connector..But that's just recommended when running SLI, but connecting it anyway might make a difference too, same as with the other 8-pin CPU connector.

    I saw this by the way, but i just have a 7820X and i didnt really decided what i can do.
    And i dont have an sli in my system.

    The second 8-pin EPS/CPU connector provides extra power for extreme overclocking, which you're not doing with your 7820X at 4.7GHz and the PCI-E 6 Pin Power Connector at the bottom-left of that board is only recommended when running SLI..But just for troubleshooting purposes I would connect them anyway to rule out not enough power as being a cause.
     
    The 2 leading causes of freezing are not enough Vcore and the RAM frequency/timing/voltage not being set correctly.
     
    I would bring the CPU back to stock frequency/voltage and try it..Then return the CPU overclock and bring the K|NGP|N back to stock frequency/voltage and try it..See if you can isolate one of those 2 things which may be causing the problem.
     
    Also set the RAM frequency/timing/voltage to the mfgr's. rated specs in the BIOS and with a 2T/2N or 3T/3N CMD (Command Rate), never 1T/1N, at least for now.
