New PC build wont start (anymore)

[joe.kelly663]

Hey all, I just finished my pc build, I turned on the pc first time it booted, but I forgot to plug in the pci-e cable to the gpu. So I turned off the computer, plugged in a 8 pin pci to the gpu, red power light on gpu turned to white, hit the power button on the case, the computer flashed as if it tried to start and then everything went dead, now I can’t get it to boot at all. I even tried to boot it with the gpu unplugged and cleared cmos and still nothing. I tested the psu outside the pc and it works fine. I tried only plugging the mobo and cpu into the psu and still wont fire up. I’m starting to think my mobo is fried. Has anybody had this problem before? Thanks.

Specs: CPU- I5 8600k
GPU- Asus ROG strix 1080
PSU- Corsair 750w
Memory- 16gb 3000mhz
MOBO- MSI Z370 gaming plus

Hi, If connecting only the 24 pin power cable, a case fan, and starting the board, does the case fan spin?

No it wont start, fan wont spin either

Then I'd RMA the motherboard.
Not sure about the cause. It could have been the power supply...
