A fan for a GPU is totally optional to get better performance. And any fan with 450w is enough, especially Cooler Master Thunder with the nice quality, a 550m is fine too

Not real sure what Akram is smoking since you said nothing about a fan and a fan is definitely not optional on pretty much every GPU. Anyway...

Your PSU is only rated for 360W on the 12V and the TDP of the card is 140W. And its a low quality PSU. I wouldn't have ever bought it in the first place. But it does have the required GPU power connector and as long as you don't have much other stuff in the system or overclock it should be OK from a wattage perspective. Personally I'd replace the PSU with a better model though

will it help if i choose to get a 960 instead since it uses around 120 TDP?
