The PSU will work great the most gtx 970 only requires 500w so that will work and the i5 4460 won't bottleneck. You will have a great gaming experience if you choose those components
So wrong on your answer a GTX 970 does not require 500 Watt power supply, it only has a TDP of 140 Watts.
People should learn what is really needed to run a PC because they say in the card requirements 500 Watts neans absolutely nothing they have no clue what is in your PC so should really only state what is needed for the video card.
To the original poster yes your fine your PC will use less than 300 Watts during a full system stress test and more around the 220 mark when gaming.
