Instant shutdown whilst gaming?

[Orch]

Not sure where to put this so apologies if I'm wrong the place.

Was mid way through a game of BF4 just then and PC just instantly shut down out of the blue. I thought we had a power cut for a second, but no.

Was monitoring things whilst playing and everything looked normal.

In the past if I had problems it would freeze up, blue screen whatever, but never had this.

Any idea where I should look for a culprit? Or is too vague to narrow down?

Hmm, yeh I'm suspecting the PSU. It's as per my sig and I've recently added a power hungry 390X as well.

Does my setup look like it would use up 600w? (no idea how to calculate these things)

Thanks for the suggestions.

It is all overclocked and pushed quite far, although has been gamed and stress tested a fair bit. Will notch them down and see how it gets on I think.

Unfortunately don't have anything to read the power at the plug.

Sounds like the CPU overheated and the thermal cut off kicked in.

Shouldn't be, unless something weird happened. It normally maxes at 48° gaming, which leaves a pretty big margin. Will keep an eye on it though.

Decided to take one thing at a time. Have reduced the overclock on the GPU first. Have just done an hour of BF4 and no problems so far. If it happens again I'll notch the CPU back as well and see what that does.

Will start eyeing up PSU prices though I think, just in case.

Best to do that 1st before spending any money

Ha, still recovering from Christmas spending so won't be rushing!

Get a Superflower one if you change PSU.

Will certainly ask for advice before hand. Will probably want to future proof against getting a second 390X to crossfire
