Yeah, that unit isn't a good pairing with that gpu. Have you observed any black screen signal losses or crashing yet?
So should i just go back to the 1060? I cant upgrade my cpu just yet.
I wouldn't. Work with what you got for now - you just need to change some in game settings.
[I know I'm being vague here, but it's because I don't know exactly which settings you'd have to turn up/down. In some games, the graphics options tell you what certain settings do to the cpu and gpu.]
If the system starts black screening and crashing on you, you won't have a choice but to replace the power supply.
Also, undervolt the gpu so it doesn't stress the psu as hard. Here's a quick how to:
Run Msi Afterburner. Unlink the Power and Temperature Limits - there's a paperclip like icon next to it depending on the skin being used.
Max out only the power limit, and click apply.
Play your games with Afterburner's own hardware monitor running. Make sure both Core Clock and Gpu Voltage are visible.
[If Gpu Voltage is not visible, go to Settings > General tab, check Unlock voltage monitoring, then go to the Monitoring tab, find Gpu Voltage, and check it.]
After a few minutes, check Afterburner's hardware monitor for the MAX Core Clock and Gpu Voltage. Memorize, or write 'em down.
Please close the game, and open Afterburner's Curve Editor. Take the max gpu voltage you recorded, and subtract 0.05v from it. Find the voltage point in the Curve Editor that matches it, or is the closest match, and click on it.
Then use the up arrow key and raise the frequency back up to the max core clock the gpu touched. Lock it with the L key, and click Apply again.
Save the settings in one of the numbered profiles and lock them. Then click the reset key.
Done.
When you want to start up a game, open Afterburner, click the numbered profile it was saved at, and click apply. When you're done, click the Reset button and close Afterburner.
Memory clock, don't touch. It's not as forgiving as fiddling with gpu core clock.
Once a running Vram OC starts to show signs of instability, things start to go downhill from there.
