Yeah, as long as it is or above the minimum wattage for your gpu then yes you can run it.

I would need to know the make and model of the PSU to tell you if its good or not. If its a decent unit it should be more than enough, if its not it could damage the whole system.

It's just a local unit here in our country. Sunstar 500w. And 400w is the minimum wattage of the GPU

After looking up the specs, from what I can find that PSU is way overrated, judging by the 12v rail its closer to a 300w unit than a 500w unit. I would suggest replacing it, and for the reason why refer to the youtube link in my last post.

First you do not have a 400w GPU. You have a GPU that requires a recommended 400 watts for the entire system.

The local, no name unit you have very likely can't supply anywhere near 500 watts. I can't even find any info about it. So even though the GTX 650 is a very low power card I would not trust that power supply.
