Desktop fans at full speed then shuts down moments after startup

[p.alstad]

My desktop has sometimes been running the fans at full speed after startup, then shutting down moments after. I noticed a performance issue in games too. I suspect the PSU doesn't have enough watts for all the components, but it has been OK the last months. So why it does this now is a mystery to me. Please help me figure out what is causing this, it has been annoying me the last week.

Specs

Mobo: 970A-DS3P
CPU: FX-6350
PSU: Cooler Master Nätagg CM B2 500
GPU: Asus gtx 1060 6GB

I guess that with "shutting down after" you mean the whole pc which might very wel be the psu looking at what quality you have.

Ye going to upgrade to a 750w soon as I get higher end components anyway, so I think thats the problem right now.

Don't stare yourself blind on wattage,it's not a measurement for quality. Your build would do fine on a 550watt psu of good quality.Better one of good quality and 550watt than a 750watt of low quality.

z170 mobo
i7-6700k
corsair vengeange lpx 16gb 3200mhz

so I think a 750w of good quality will be better

If good quality sure fine.Something like the TX750M form Corsair,BitFenix Whisper M or the Seasonic Focus gold,trying to look at still a decent budget.Not including the occasional sale that is offered.

Settled on the EVGA SuperNOVA 650 G3, I don't like corsair's PSU's

Pretty biased about Corsair psu's i see,but that's up to you. Just to mention,Corsair doesn't make their own psu's,they put their brand on something that they together with the oem of the psu came up with as a design. Oem can be Seasonic or Great Wall or other company that really makes the psu.
For instance two reviews about the TXM i mentioned (and use),

To the point,both psu's you mention are a good choice,which is up to you. Can let price decide.
