Dead Gigabyte Mobo?

Hi All. Recently my desktop won't boot up where there was no more power going to the motherboard and no fans turn on etc. I do see the LED on the 3.5" USB hub in front of the tower light up, but it would promptly turn off when trying to power on the system.

I bought a new eVGA 750W psu thinking it's the culprit but the same symptoms exist. I tried booting up with bare minimum of monitor and power cord but still no go. Do you guys think it's the motherboard or some other culprit?

System specs for reference:
Motherboard: Gigabyte Z270-HD3 V1
CPU: Intel i5 (forget which model honestly)
RAM: Team 16GB TLGD416G3000HC16CDC01
Graphics: None. Using integrated Intel
New PSU: evga EVGA SuperNOVA 750 G5
Old PSU: Corsair TX750W

Did you try pulling the system out of the case and just running it on a desk? I've had motherboards power cylce like that if something was shorting out.
