How old is the unit? What CPU are you using? How many SATA devices?

You'd really do better to just give us a list of all the parts you currently have in your build. My gut feeling is that it's not powerful enough, but that's mainly a guess from the lower quality of the unit and the fact that older cards require a lot of power.

2- 200mm fans - / 1- 120 mm / mobo, 4 gigs ram 4890 xoc, ultra u12 cpu fan, phenom 2x4 940 be 3ghz / seagate 1 tb harddrive lg dvd rom. and gonna but another 4890 xoc in crossfire (what I was thinking is that if anything I'll take out my dvd play and or a fan to use up less power) what you think in all?
