Considering it's a CM with no trustworthy ratings given, i'm more inclined to say it's junk.
Cause I have that PSU should I use it or buy a 600W
Well, considering that your cpu doesn't draw much power i'd say it's probably ok for now.
However, if you plan to upgrade your cpu any time soon then i'd recommend a new psu.
Something like an EVGA G2 650W or Corsair RM650x, on a lower budget the Corsair CX650 is a great option.
