If you have no lights on mainboard, it is highly likely that your psu went bad. I think there is one more fuse (near AC plug and power switch) that you can check. If it's OK, then PSU is dead, contact your seller, he should be able to help you.

Thank you wotor.
I'll check the power supply tomorrow.

Hi, You can measure whether the output voltage of the power supply is 24v.
If the voltage output is correct, the motherboard needs to be replaced.

Ok, thanks for all your answers.
I'll try this tonight and I come back to you.

So....
Power supply is dead.
I'll see with the seller if he can send me another power supply.

Thanks all for your help !

Hi, You can measure the output voltage of the plug that is plugged into the motherboard.
If it is still 0v, you need to replace the power supply.
I hope this can help you.

Thank you William, I'll try this tomorrow.

Hi everyone,

So I tried and still get 0v output.
I decided to unmount the PSU, and I checked my input (240v here in France), and 0v output : I have contacted the reseller, he should send me a new psu.

Thanks everyone for your help !

good
