Hello all.
So I was playing World of Warcraft yesterday and my computer randomly just shut itself down completely, no BSOD nothing just boom turned off.

So I did a little googling and most point towards a failing psu so before sinking £60-80 on a new psu I wanted so see what you guys think might be happening.

Cpu temps are normally around 40-55
Gpu temps is around 50-75
The psu fan seems to be spinning fine also.

Specs -
I7 4790k
H75 corsair water cooler
Gtx 970
1tb hdd
120gb ssd
8gb corsair ram
Seasonic psu

Any help or options is much appreciated.
