Hello everyone,
My new gaming setup (home-built) trips my main circuit breaker as soon as I plug in the power cable.
I'm not at all knowledgeable about electricity... could you help me diagnose the source of this issue? (Power supply too powerful, electrical problem, faulty power supply, bad connection...).
The power supply in question is a Corsair TX650.
What seems very strange to me is that the circuit trips as soon as I plug in the power cord, even though the power supply switch is off.
I've tried multiple outlets in other rooms, and there is ONE outlet where the circuit doesn't trip when the power supply is plugged in; it's located near my breaker box... I haven't tried to turn on the PC... and I'm hesitant to do any more blind tests for fear of damaging my setup (if it isn't already done).
Thank you in advance for your advice.

In general, if the circuit breaker trips when plugging in a device, it's either a short circuit or an earth leakage.
Since it happens with several different outlets, I would say the problem comes from the PC.
As a risky test, it would be to take out the power supply, place it on the ground, leave the switch on Off, and plug it in. WITHOUT TOUCHING the power supply casing, because as it is, we don't know which component triggers the short circuit or generates the leakage. And since power supply casings are metal...
If the same problem occurs while plugging in another device causes no tripping, we can say it's the power supply.

If you're blowing fuses with a 650-watt power supply, you probably can't even iron your clothes (1200 watts), or cook a roast in the electric oven (1500 watts), let alone reheat a coffee in the microwave (minimum 700 watts)^^
In my opinion, only an electrician can help you check your outlets!

After unplugging all the power supplies from the PC, the circuit still tripped (the power supply still screwed into the case).
I took a look inside the power supply to see if a screw had fallen in, and I noticed that the screws I had used to secure it were a bit too long... I was able to screw them all the way in, but it was a bit tight at the end... I then realized there was no stopper, and my screws had probably touched/pulled out a conductive element, putting it in contact with the casing of the power supply.
I removed the screws to replace them with shorter ones, and miracle, it works.
I hope the power supply hasn’t suffered too much... I don’t know how to check that without opening it. In any case, the circuit doesn’t trip anymore, and the PC works perfectly.
Thanks anyway for your advice that put me on the right track.
It would be more prudent.
