I checked with CoolMax's site and I do not see a CA-600W PSU. They only have the 300W, 350W,400W,and 450W model. http://www.coolmaxusa.com/PowersubCategory.asp?item=80mm
Please double check the PSU specifications. If your PSU is one of the above models, it's no wonder that something goes wrong. Furthermore, I do not have confidence in CoolMax PSUs, so if it's possible you should grab a Corsair or Antec or any named brand PSUs. A 500W solid PSU should be enough.
