For the past few days my computer has been randomly turning off, now it got even worse, it suddenly shut down and when I tried to turn it on it seems like only a couple components here and there turn on. I removed my GPU to see if I get some message from the onboard graphics but then everything worked fine, so I'm writing this now on this computer. But what is the problem then? Has my power supply suddenly become too weak or has my GPU suddenly started stealing the power form everything else? Previously my system has worked fine under 100% load as well.

My power supply is 600 watts (should more than enough according to power calculators I just checked with)
My GPU is a GTX 1070

Thanks for any answers

I guess there's nothing I can do then.. Which new one would you recommend? I'd prefer to get something that is good value, not the dodgiest cheapest one but I by no means have the money to buy the most expensive one either.
