So I have just bought the new Middle Earth: Shadow of Mordor and was playing it for around 20 minutes before going for my tea, which took around another 10 minutes and when i returned and resumed playing, all the power went off in my house and there was a huge flash and bang from around the back of the PSU area of my PC... Now it wont turn back on! What the hell do I do?!

Looks like you need a new PSU - something probably fried on the primary side from a surge. If whatever PSU you got or the PC as a whole is still under warranty, get a repair/replacement.

Buy a new PSU if you can't get it replaced. It's 100% dead, and might have taken out components with it.

Well I recently installed a graphics card into the PC that I got pre-build, would this affect warranty? I assume it would?

Which one? They have a pre-approved list. What GPU and pre-built did you have?

500w should power a 270x. Contact them about it. Chances are warranty doesn't cover that honestly, but I would ask. Also, if you had a power protector attached contact them. Some have multi-thousand dollar warranties.

Thanks a lot for all the help, just out of interest, do you think it is likely that any of my other components will have been damaged? The PC was a gift for my recent 16th birthday so if potentially fatal damage has occured then my family will be furious... I will be taking it into a repair shop tomorrow to find out but I would appreciate some peace of mind.

Oftentimes a blowout like that can have killed multiple components. I've seen everything thing be fine after a dead PSU and I've seen the motherboard, CPU, GPUs, RAM, and even fans all dead. If it did take something else out I suspect it will probably be the mobo. Honestly if more things are dead just explain that nature took it out. Not much else you can do. :\ Also, if the repair shop tries to sell you stuff be cautious. I hate shops like that in the US.

Primary-side failures rarely cause issues on the output side since the input-side component will self-destruct much faster than output voltages can rise when there is a primary-side malfunction.

Random components usually get fried when a secondary-side or control loop failure occurs.

Since your PSU failure was related to a power outage, a primary-side failure is the most likely option so there is a high probability the rest of your components are fine.
