I'm new to making computers and wanted to know if this, 600W EVGA 600B, 85% Eff', 80+ Bronze Quiet Power Supply is enough for my system?

I will be using an AMD FX 6300 CPU and a Sapphire radeon R9 270X as my graphics card.

Also is this power supply reliable or is it likely to blow out?

Lastly would this be a better PSU and is 550W enough?
