You only need 30A on the 12V rail and 500W total minimum for a gtx 760.
The coolermaster can supply 54A - http://www.coolermaster.com/powersupply/modular-vs-series/v650s/
Its made by Enhance and is 80plus Gold certified. The V series are better though - made by Seasonic.
If you already have it then use it. Else try something from Seasonic eg their 520W or XFX550 or Antec HCG 520M
