Question:
Can my PSU handle everything for my system??, im also planning to upgrade my ram to 16 gb.

or What is the Power Supply recommended for my system ?

The only component that takes significant power is the graphics card.
Fans ram, etc take very little.
If you are running well now, I would expect no problem.

But, why in the world are you adding fans?
Fans do not cool. They only move hot air out of your pc.
Your parts need no exceptional cooling.
You are spending $ to increase the noise in your pc for no real reason.

Spend that cash elsewhere.
I would look into a SSD.
