My build-AMD 6350 at stock clock 6 core.

ASUS 990fx Gen.3 R2.0 Mobo

8Gb of gskill ripjaws x series at stock clock.

it should do the job but dont do any more.

If it has a good efficiency rating, it should be enough. Check to see if it is gold rated, or anything bronze and above.

is that a OCZ modstreampro? I read some reviews where it would fail at full load (650W)

650 watt should be enough but I'm afraid the PSU doesnt have a good reputation..

No it's not
