Default powersupply issue

When I'm playing certain games (GuildWars2 on high settings was a problem yesterday) my PC will suddenly and with no warning turn off. I've run some OCCT stress tests and can only replicate the problem if I run the power supply test, the CPU and GPU tests run fine.I Googled around for what could be the cause. It seemed like insufficient power could be the issue? I've checked and I've got a 750w PSU , Speed Test Scrabble Word Finder Solitaire and PCPP says that my machine needs 361W, that's a healthy buffer right?
What else could be the problem? What else could I try?

Also, if some you experienced PC builders could take a look at my current build, does anything seem woefully outdated? I'm happy with how my machine runs currently but it's in my head that I might need to upgrade something soon. What's likely to be the component that needs switching out first?

Posting the full PC specifications would probably help.

Then it's probably less than that.

I've got a 750w PSU
Model? Just because it has 750W on a sticker, doesn't mean it can output that kind of power reliably.

Yeah. You really need to tell us what 750W you have. Many 750W PSUs aren't really 750W PSUs.

Other thing to check: Is the fan spinning on the PSU? Dead fan could cause the PSU to overheat and shut down.

Inoperative fan; I like that conjecture.
