Hello, I have this problem. Today I woke up and everything was fine. In the evening I left home to go see a couple of friends. When I returned home, everything was fine. I turn on the lights, turn on the TV but the moment I press the power on my PC, the RCD of that room in my safety switches box tripped. After some time of figuring wtf is wrong, I disconnect the PC power and push on the RCD and all went live again. If I reconnect the PC power, the RCD trips and all goes black in that room. So I figured the PC is the faulty device. From previous problems, I thought that if something is short-circuiting inside like Mobo or DVD-rom etc the PC won't turn on but not trip the RCD. Also when I came home all seemed normal to the moment I pressed the power on my PC and the RCD tripped , now it trips the moment I connect PC's power cable, so I have left the cable off the wall. The PSU is reletavly new (XFX TS750) bought less than a year ago, when my old PSU started failing (after 7 years of working). What do you guys think? Is it the PSU or something else inside? How can I tell? Maybe is the RCD of the house but everything was ok when I left and came back, to the moment I pressed the turn on. Now if PC's power cable is connected the RCD trips.

1. Try a different device in the same socket, i.e. an electrical tool. It needs to draw about the same power as the PC. If it trips the RCD call an electrician.
2. Try a different cord between the PC and the same socket. There could be an internal short in the cord or at either plug.
3. Try the PC in a different room, i.e. different RCD circuit.

To add on to what I wrote above. I think the PC is stuck on the "I try to turn on" status, meaning if all goes well and it gets proper power it will turn on without me pushing the power button. I don't know if I use the right terminology but I'll say it how I understand it. The PC trips not only the room's RCD but the house power breaker too. To explain , when the PC tries to drow power the whole appartment goes black. When I switch the appartment's power breaker on again all the other rooms get power back except the PC's room, even with the PC cable off the wall. I have to wait a minute or so and after some time of me up/down that room's RCD finally I get power there.

Hey guys. Let me tell you what I tried. I gave the PC different power cable, plugged on another part of the house, even plugged it on another apartment. All of the above tripped the RCD. So I thought it's the PSU. The moment it has power it trips the RCD. So I took the PSU off and sent it back. It's very strange that the PSU broke so early (I have it since April 2015). Can it have damaged other stuff in the PC? I hope not.

Another update on the situation. As I said I took the PSU out of the PC and gave it power and guess what, the house went black again, so I took it back to take my 5 year warranty (have it since 15th March 2015). Now I am sitting here on my sister's ultra laggy old laptop thinking what else can I do and then I remembered my old PSU (the one that started failing after 7years of use). I connected the CPU pins and the the Mobo pins from my old PSU but didn't turn on the PC, I just wanted to see if the house will go black again with another PSU connected to my PC. Once I gave it power the lights on my Mobo and around the PC lighted up, even the Graphics Card went red signaling I haven't connected power to it. Now I left it there, don't want to turn the PC on with the old failing PSU. The PSU that broke for me in such little time is XFX TS750, I though it was considered OK. I bought it on sale for 75euro but now that I took it back, they still sell it but at 110euro. If I use the warranty I don't have to accept the same PSU model, I have the option to tell them to allow me to buy anything else from their shop using the money I paid for the broken PSU and if needed add some more. I don't know which amount they will give me (75euro I bought it or 110euro they sell it now?!) but in any case I am thinking of buying SEASONIC S12G-750 750W since I saw it on the PSU tier list, being on the 2nd tier from the top and they have it on sale for only 130euro. What do you think?

I couldn't agree more with you. After my old PSU fried my old Mobo I am on this side when it comes to power source of a PC. Spending though 200+ euro on supply unit is something I can't do. The one that did all this to me the last couple of days is XFX TS 750W. I though XFX was a good company when it comes to PSUs, and I also thought they were using Seasonic parts but it seems I was wrong or maybe unlucky with this one. Do you think the SEASONIC S12G-750 750W isn't good enough?! It's Tier 2 rated here on tomshardware PSU list and Gold rated in terms of power efficiency, not good enough? Can you suggest something else if not that one? My system is:
Intel Core i7 3770k
Asus GTX970 Strix 4GB
Asus P8H77-v LE (mobo)
4x Corsair Vengaence 4gb DDR3 1600mghz
