i had 500w when i got my amd r9 270x and it it died he needs higher psu
The 270X has a 180W TDP, the 970, though it's much, much faster, has a lowly 145W TDP. The CPU pulls under 100W. Even heavily overclocked it's really hard to get an non "E" series Intel CPU to pull more than 200W. In that case you're still at under 350W for CPU+GPU combined (which is the vast, vast majority of system's power).
FYI - the 80 plus ratings measure efficiency, i.e. the percentage of energy wasted to heat, by the powersupply at a range of load-levels. It can sometimes allude to the quality of the unit, but it only really measures efficiency. If you want a reliable and quality unit, look to trusted reviews, not an 80 Plus rating.
XFX (they exclusive use Seasonic I believe) are one of the best in the business.
OP, unless you're chasing substantial overclocks on both CPU & GPU, a good quality 550W (like the unit suggested above), is a perfect fit for you build.
