Problem gpu speed

[zergo1012]

My gpu: Msi r9 290x gaming 4g. Is not clocking to 1030mhz which is the default clock. When I run demanding games like Ac unity, company of heroes 2 my pc shutdown, I think at power peaks. That's also why I think it's my power supply incapable of supplying enough power.

What do you guys think what I need to do to solve my gpu and my pc shutdowns?

 

My power supply is a Ocz modxstream 600watt. It's a 80 plus bronze powersupply

What cpu , if overclocked don't. Run a benchmark see what happens.

I have 4770k at stock speed (mostly at 3.9ghz turbo boost because of my h100i)

normally I would say 600 watts is way more than enough, but if the power supply is old or defective that make more sense. 

 

the 290/x cards will only reach full clocks when needed. AMD Powertune 2.0 will adjust the clock speeds as needed 100,000+ times per second to optimize power draw.

Take gpu out, test it. Occt has a pic load test. I don't know much,sorry. What are temp? Does it shut off right away or only heavy load?

Can't edit on phone. Psu test.

I did the test and with gpu my pc shuts immiadatly down. Without it works but I see that my psu is giving on the 12V+ rail 11.18V. I think that's not within the 5% margin

By the way it's only happening on heavy load and my temps are: cpu 66 degree Celsius and gpu 76 degree celsius at almost full load
