Random reboots with sparks coming out of GPU

ok so a month or two ago i decided to upgrade my motherboard, CPU and ram and i went from:

Intel 2500k
8gb of DDR3 ram
GTX 780
random atx motherboard (cant remeber which one)
600W OCZ semi-modular power supply
2TB seagate HDD
250GB samsung 840EVO

after upgrade:
intel 8600k
Z370-A PRO LGA 1151 DDR4 ATX MOTHERBOARD
16GB (2X8GB) Corsair Vengeance lpx black
600W OCZ semi-modular power supply
gtx 780
2TB seagate HDD
250GB samsung 840EVO

so after the upgrade i was getting random reboots and for the first month i thought it was to do with the intel chipset security flaws, which were causing my friends pc's to also randomly reboot but 3-4 days ago i had a random reboot and i happened to look into my pc when this happened and i saw what appeared to be a spark come out of the GPU (see picture from where it came out off https://imgur.com/a/UxTpq ). This then happened again to day and its worth noting that this only happens when i am playing a game and sometimes it happens once a day but sometimes it doesn't occur for weeks. after i saw the spark for the first time i took the side of my case off in hope of getting a better view next time it happened and i saw and heard like a fizz (hard to explain) and i saw very faint sparks (due to the fact the case had light now that the side panel was off but i have no doubt if their was no light i would have seen it better)

- My cpu temperatures are fine (idle 22-30 degrees and while full load 60-70). I also checked the last recorded temp in my logs before each reboot and didn't find any unusually high temps.
- The PSU and GPU both are the oldest components in the PC so i am quite sure either the PSU or GPU are causing the problem although i have no way of knowing which as i have no spare components to test them both. ( don't want to spend allot of money on a gpu if it then turns out to be the PSU causing the issue and visa versa)
- I've tried using different wall sockets and even at a different house and the issue still occurs.
- Cleaned all the dust out of the PC.
- Could it be to do with my new motherboard and cpu? i wasnt getting this problem before i did the upgrade. Could this happen when not enough power is provided by my PSU for the new hardware?
- do i put my computer at risk by continuing to use it?

any help would be greatly appreciated

how can you so sure that its the PSU causing the issue? if you are right do you have any suggestions for what wattage i should choose? i would be willing to spend up to £100 and maybe slightly more if that is required.
