While the make of supply isn't on the "good" list here it should have enough power normally for the average user. The specifications seen at newegg show:
+3.3V=20A, +5V=30A, +12V=18A, -5V=0.5A, -12V=0.8A, +5VSB=2A

You can compare those to an Antec supply with:
+3.3V=20A, +5V=20A, +12V1=17A, +12V2=17A, -12V=0.8A, +5VSB=2.5A
I had to substitute the "@" for the "=" to keep those from becoming links! When going to perform the Direct X test you shouldn't have seen that unless one of two things happened namely the supply is unstable or you ended up with a bad card.
