nox nx 650w enough for gtx 770?

Solution
I looked on http://www.realhardtechx.com/index_archivos/Page2438.htm but did not see "NX." Is it "NXS" or "NXHM?" If it is made by CWT, then although it should be enough, it may not last.
Based on http://www.realhardtechx.com/index_archivos/Page37026.htm about another CWT-built NOX, component quality is consistent with CWT, which is to say sub-par. It isn't going to kill your system if/when it dies, but if yours also has only a two year warranty, there's likely a reason for that (most "good" PSUs are warrantied for 5-7 years, with the best offering 10-year warranties).
So yes, it is enough, but it may not be a high quality unit.
