Pc shuts off

[nitra93]

My system is a fx 6300 with a gtx 780 ti. i am aware of the bottleneck but everytime they are both put under load for example playing gta v. my pc just cuts the power. i'm assuming my psu isnt good enough. it says it's 850 watt with 36 amps. any ideas?

try checking the power connections. also check for loose fans and cooling connections. GPU should be fine (I don't know what settings you're trying to run at, nor the resolution). You might try upgrading to an i5-4690k. much better CPU all-around.

850W should be more than enough for your current setup. I'm running an i7-4770k 4.2ghz with 2way 2GB GTX760s on a 750W corsair gold.

Your PSU is the problem, you need 42A. Also any 850w which can only deliver 36A is really bad quality and unlikely to achieve 36A

36a on a 850w PSU is absolutely horrible, that means its only rated for 432w on the 12v rail which is what most good 450w PSUs can do and is nowhere near enough for what you have. What's the make and model of that PSU shaped object you are running?

That's what i was thinking, because it never bothered me with the 680 i had before i never thought anything of it. thanks for the help

Your 750w PSU also can deliver more than 36a on the 12v rail. A good 850w PSU should be able to deliver somewhere close to 70a on the 12v rail(s).

Consider yourself luck that it hasn't killed the system. Such low quality power supplies are infamous for failing catastrophically a destroying systems and even been known to catch fire.
