New PSU, No signal detected for monitor

[xzodi]

Hello, recently my Corsair RM650x PSU stopped working. The PC wasnt turned on, I woke up to a BANG sound..
I got a new RM650x PSU from the warranty and installed it today.

The PC turns on, but it says "no signal detected".
Tried to remove other components from the pc.
Tried with different dvi/hdmi cables
The monitors DO work.
Tried to boot without the grapich card.
Tried to reset the BIOS (removed the battery)

I'm scared that my MOBO or CPU has been damaged..
Is there something else I could try?

My other components are:
Asus prime Z270-A
G.Skill RipJaws VKB schwarz DDR4-3200 2x8192mb
Intel i7-7700k
GTX1070

THE BANG PROBABLY TOOK out the board.

I agree. You can try connecting an internal speaker and starting the board without RAMs. See if any beeps.

If you don't see any drive activity (lights), it's probably the MB and/or CPU. If the drive lights are active, might be the graphic card.
