New build instantly turns off

[Implosion]

Testing Video (Streamable)

 

As you can see from the video, this is a fresh build (without gpu, os, or anything). Within a second of being turned on, it immediately turns off. However, when the CPU power cables are unplugged, it seems to power on just fine.

 

Specs:

• i5 7600k (LGA 1151)
• EVGA 650 G3
• MSI Z370 Gaming Plus
• Corsair Vengeance LPX 8GB DDR4 3000MHz

 

What we've tried:

• Replaced Motherboard
• Replaced CPU
• Replaced RAM
• Replaced PSU/Cables
• Replaced CPU Cooler
• Swapped Power Outlets
• Shorting power pins to avoid possible broken button
• Reseated CPU (and checked for bent pins)
• Reseated RAM

 

Disclaimer: I did not participate in the building, nor testing process of this rig - I'm simply helping troubleshoot.

Do the fans spin up and then stop?

 

Is there a click from the PSU? If so, then you have a dead CPU and/or motherboard.

I might be wrong but Z370 is for 8th gen cpus not 7th

Have you tried booting the system with nothing plugged into any of the I/O ports except the power cable?

 

EDIT: Sorry didn't watch the video

Yea, there's a click.

 

What're the odds we got two dead CPUs and/or Mobos in a row, though?

You’re using a 7th gen cpu with an 8th gen motherboard and intel does not like that one bit

Meaning they're just preventing it from booting, or the CPU(s) are fried?

I don’t think it’s either of those but the cpu should be fine (I think)

I'll check back once we've ordered new components and tried it.

He ordered a 7th gen Intel motherboard and all was well. Thanks for the help!

Good thing it was just a simple mistake!
