Hey guys

I need help with this issue i'm having right now.
I built a system a week and a half ago:

Intel Core i7 7700
Asus ROG Strix H270F Gaming
16gb DDR4 RAM (2400mhz) 4x4gb - Corsair Vengeance LPX
EVGA Geforce GTX 1070 SC
A couple of inherited SSDs (120 and 250gb) + 350 gb WD blue HD.
EVGA 650 GQ PSU
Corsair H80i V2 AIO

I had assembled it on an older case a Corsair Carbide Spec Alpha, and while the build was a pain because the case is not very good.
It posted on the first try. And it worked without any issue throughout the week.

I bought a new case to make the system cleaner in terms of build, a NZXT S340 Elite.

Today i disassembled it to put in the new case. I didn't touch the CPU, memory or the AIO installation. I just took out of the old case, and placed it on the new one. Routed the cables, Plugged in everything and...
When i was finally done i went to turn on the PC and this happened:

When i flipped the PSU switch No fans spin (not even when they try and stall). No Beeps.
Just the Stand by power led (picture attatched). Flashing orange. Like Flash, slow fade. I press the power button, nothing happens.

I tried unplugging and replugging the 20-pin power cable and the 8 pin CPU power. Nothing.
I checked my front panel conectors and they seemed to be installed correctly.

Can you guys shed a light on what's going on?
I'm at my wit's end here.

Thank you for your time, in advance.
This is a real bummer,

Sounds like there's a short somewhere causing the 5vSB rail to cut on and off. Did you use standoffs on the new case?

I did.

I changed one of the standoff (the right botom one) wasn't catching the screw's thread.
After that, i reassembled it outside the box, tested it, worked.
Reassembled inside the case and it worked.

Next time i'll be more careful with the standoffs.
I didn't know they were more than just mounting pieces.

Seems like this was the case.

Thank you!

IT LIVES!!
