Hello guys
 
 

 
we got 2 of that awesome board for myself and for my friend.i booted mine  up without any problem.
 
my spec is below
 
corsair h110i gtx 
 
gskill tridentz F4-3000C14Q 32gb
 
6850k
 
1200p2 evga psu
 
evga 980 ti classy
 
but for myfriends spec below
 
6800k 
 
corsair 32gb  CMK32GX4M4A2666C15
 
Corsair Platinium HX850i  psu
 
corsa h75 cpu cooler.
 
evga gtx 1070 FE
 
it everytime stucks at post code 68.What can it be? i tried the ram sticks one by one but no luck.i have reaseated the cpu and looked for any bed pin but there isnt any problem on the cpu socket area.
 
is it possible that the board does'nt support 6800k righ out of the box? but my 6850k just ran fine and could update the bios to v2,01.
 
other chances are having 
 
bad ram modules(all 4 sticks cant be DOA at least one of them should have been worked :)  )
 
the other one is bad DIMM slot? 
 
i start installing ram kits into the first dimm slot and then into the 3rd one then into the 5th and 7th one.
 
i tried to start installing them first into the 2nd slot and he computer ended up in endless loop tries to power up and shuts itself down , then tries to power up shuts itself down ......
 
so what can cause this?
 
i didnt install any hard drive or m.2 ssd while trying to boot up the computer.just the cpu pomp cable and fan cables.
 
i took out the Mobo out of the case and tried with 1 stick with cpu and without cpu and without RAM i did everything i could.And it only states C post code.
 
can it be a damaged PSU (it has been bought with the system and it is brand new.)
 
or the CPU which is very rare.
 
you will find the related videos below.
 
 Nothing happens;
 

Now i could boot the system up nd got into the bios.what i did is changing the psu with the codegen brand 300w :)

No more C post code.but another issue is even the leds light on the board sometimes it didnt power on by pressing the power button on the board.

I believe corsair is having compatibility issues with the board and the 300w psu is not stable.thats is why the power button doesnt start up the motherboard i think?

Thank you for your answers guys.i found another psu which is thermaltake 600w and it works great.

So is this the compatibility issue between the corsair psu and evga board? Or

Is the corsair psu damaged ? It is just brand new.we bought it on the the day we placed the order for the mobo.

It's possible that PSU is not compatible (or faulty) with the board. Even Jay 2 cents run into this with his Classified X99. His Cooler Master -whatever- PSU just activated over-current/voltage protection instantly during power up and that was it. When he used his EVGA PSU problem was miraculously solved. I ran into this with multitude of PSU and cheaper UPS battery backups. Manufacturers never advertise this 'feature' that cheaper UPSes are not compatible with active PFC... Something that is basically standard for past 15 years or so in every consumer PSU. Effect was exactly the same - instant OVP activation on the UPS.
 
One of the reasons why I went with new EVGA PSU when I bought my Classy. With newer intel CPU and ATX power specs I wasn't so sure that my old Corsair will do the trick (even if Corsair certified them for X99 platform, still better safe than sorry).
