I was just wondering if a TR2 600w thermal take power supply is good enough for over clocking intel i7 4770k and powering a radeon r9 270x graphics card. If you have any suggestions of upgrading my power supply or graphics card, please let me know. My motherboard is a gigabyte GA-Z87X-UD5H and my cpu cooler is going to be a corsair h100i dual 120mm fan. Another question I have is if I should replace the stock fans that come with that cpu cooler.
