[SOLVED] Don't know if this is a PSU issue or Graphics card issue

[Hendubz84]

Hey everyone, I'm hoping someone can help me.

I've been having a few issues where my PC instantly shuts down and then restarts when I'm gaming. I've done lots of searching to find out what could possibly be the cause but so far I've not found anything that has resolved it and I'm worried it may be a hardware issue.

Here are the specs of my PC, if I've posted in the wrong place then any guidance is much appreciated.

Thanks.

if you think it might be a psu issue, you might aswell tell us what psu you have. how much watts?

Most of the times when your pc shuts down and restarts especially when "stress" is applied (like gaming) it is psu related

Do you have acces to another psu unit (maybe from a friend)

I don't have a spare unit or access to a spare so it would be something I'd need to buy.

your PSU can handle even a 1080ti, so if its not old its a GPU problem.
