So, here's the little back story... I recently moved back home with my parents for a few months and haven't put my pc back together for a few weeks. I decided to plug everything back in now i've settled back in, everything worked, PC was on was browsing the internet everything, PERFECT. Dad came home and tried to turn on the TV in the other room and it poped the fuse in the main fuse box, so he went to reset it, turned it back on, and then!... My pc didnt turn back on, none of the red glow on the motherboard was on when its plugged in was working... something was wrong. I did abit of searching around and and it looks like my PSU has been killed, RIP, is there anything I can do to revive it? can i be sure its the PSU? do i just need to suck it up and get a new one?
Below I have listed my PC components, Cheers, Tom!

CPU - Intel - Core i7-4790K 4.0GHz Quad-Core
Motherboard - Asus - MAXIMUS VII HERO ATX LGA1150
Memory - Corsair - Vengeance LP 16GB (2 x 8GB) DDR3-1600
GPU - Gigabyte - GeForce GTX 970 4GB G1
PSU - Corsair - RM 750W 80+ Gold Certified Fully-Modular ATX

it sounds to my ear like the inrush current killed the PSU, when your dad hit the breaker the surge of the circuit powering on may have been unsafe.
I would suggest a good surge protector replaced every 18 months. the clamping speed on the surge protectors wears down over time and older surge protectors (24+ months) are just power bars.

There really isn't anything you can do to fix a dead PSU. Try a different plug and power cord. The only way to be sure that it's dead is to try a different one that is working. I would say to just buy a new PSU and a surge protector if the plug change and power cable change doesn't work.
 
I suggest you get the circuit checked by an electrician because a TV and your computer can't draw over 15 amps (unless it's a TV that draws 12-15 amps when powered on, but then it would require its own dedicated circuit). The TV may have caused the issue, but you should probably find out before blowing something else.

We live in a fairly old cottage and just tend to ignore the electrical problems, it's good most of the time aha!
