520W is the recommend PSU wattage for the OC 7770.

Wattage isn't the only factor though, you'll also want to make sure the quality of the PSU itself is good. Many people try and get a cheap PSU with the right wattage and things still end up going wrong.

The XFX TS Series P1550SXXB9 550W is a great tier 2 PSU from Seasonic that should run your rig just fine:

please write all your PC specs and hardware. Your PSU has barely enough power to handle your GPU but it doesn't matter, there could be a lot of reasons for this kind of crush.
You can start by making sure all your cables are plugged correctly, change the 6-pin GPU power connector to another one (have you even plugged it in the 1st place?)

update me if any of this helped

well so the guys here are right.. you obviously need a new and better PSU, aim higher then 500W and at least 80+ bronze certified, i suggest going with good brands like seasonic, XFX, etc

This PSU will do the job
Power Supply: XFX 550W 80+ Bronze Certified ATX Power Supply ($51.99 @ Amazon)
Total: $51.99
