PC doesn't start even with new PSU

[raxy]

Hi everyone. My PC suddenly turned off and i cant turn it on.The mainboard has LEDs lightning, GPU too.
I changed the PSU, removed GPU, RAMs, HDDs and tried to start with the PWR button on the mainboard but still nothing.

I can't smell anything burned or something like that.

Is it possible that the mainboard (Asus x99-A) is dead?

Yes, but we need more info.
Try
- different power cord to PSU
- a different outlet
- Turn PC on outside of case using screwdriver/similar

And let us know what happens.

Tried 2 outlets = same
Tried with to connect pwr_sw with screwdrier = same
The 2nd PSU is a new one. Just ordered to test with it.

Just because a power supply is new does not mean it is not faulty. I have been burned more than once with bad power supplies that I had just bought.

You need to put memory back in, computer wont boot without it.

There is no boot. The PC isn't even responding to the power signal. Nothing happens. PSU is fine.

Disconnect 24pin power connector from motherboard.
Have fans and hard drives plugged in.
Take a paperclip and jumper from the green wire in the 24pin harness to a black ground wire in the same harness.

If PC powers on then PSU is fine and your issue is likley that the old PSU fried the motherboard.
Do check the power button connecteors as well.
If PC still does not power up with paperclip method then your replacement PSU is bad.
