Pondering :
Short answer: Get a 750 or 650 Watts if you are planning on leaving it overclocked. However even if you just just overclock just temporarily for gaming or resource intensive programs it is still cutting it close.
It depends on the PSU. I am not familiar with Amperage so I estimate by reducing the wattage by 20% so the wattage would be considered at 440 in this instance if it were a quality power supply with the fx 6300's max TDP at 95 Watts and the 270x's max TDP at 150 Watts. The combined TDP is 245 Watts or 56% of 440 Watts (the PSU's 'rated' capacity reduced by 20% for power lost as heat). It is best to keep the PSU's constant load at 60% or less unless if you swap out PSUs quite often then do whatever you want.
Thank you for your information. I thought of overclocking at first place but thinking to withdraw from it as I need to spend the money on PSU as well. Apparently, I need to bear the expenses on both PSU and aftermarket cooler, if I stick to OC. Instead, is it okay to upgrade my processor to FX 8350? The Price of both PSU and aftermarket cooler is almost similar to the new FX 8350 Processor. As I'm new to overclocking, I prefer buying a new processor itself. What's your opinion on it?
Upgrading to a fx-8350 is not really worth it. You can tell a difference but not by much, atleast in games.
As for overclocking it should work just fine on that psu. But you better just try yourself, your gpu won't pull that much.
Just increase the core clock, it shouldn't affect power usage that much. PLUS, the fx-8350 draws more power.
