Upgraded cpu/mobo - no post
 
Had a rig with a 1080ti, and an i7 4790 w/ a Cx600 psu.

Swapped out the board/cpu with an 8600k and now it doesn't post
lights up for a split second and shuts off right away like something is shorted.

Weird thing is, If I pull out the gpu and replace it w/ a basic GT740 gpu it boots up fine.
Also boots up fine if I power the 1080ti with a second psu.

Any idea what is going on?

Really wouldn't expect this rig to need more than 600w, especially not to just post.

Up and running with another psu.
All I can think of is ocp is tripping just charging the capacitors.

If anyone has a better explanation I would love to hear it.

Because the CX600 is not a good PSU

Mostly what a quick search has found is just more complaints and badmouthing. I did find https://www.soundonsound.com/forum/v...p?f=20&t=24564 if that's allowed, where, if I read this correctly, re-setting something in the bios got him booting. Not sure if that will help. Maybe over at Johnnyguru they have info.

Cheers,

Mac
