That particular unit is pretty good for a mainstream user.
It's not crap but a level below Seasonic,Corsair,Antec,and XFX.
Btw i run a Corsair HX-750 in my main rig and use OZC ModX's in two other rigs.
OZC's offer a very good value price/performance wise.
They're quiet and reliable in my experience.
I often recommend them for those on a budget.
If you can pony up extra cash i recommend XFX.
