Question 600w psu for 150+w

[PGL]

My build is around 150w. I'm wondering if I should get a 600w psu as i want to upgrade in the furure.

Psu : Thermaltake PS-SPD-0600NPCWUS-W SMART Power Supply, 600W

Build for the system you plan to end up with along with overclocking then think to yousdelf "Do you really want to put your expensive GPU at risk with a $35 PSU?"

Don't get me wrong, I have Thermaltake PSU's but not in my gaming rig. GPU's cost too much money...

its my first time building a gaming pc and i dont know much about psu . what kind of psu should i get if im planning to use this build for the long run which is budget friendly? Currently this build is around 850 SGD and i would like to keep it below 900 if possible.

Here are my pc build specs.(hopefully they help)
