Ok i know this video card needs atleast 300W psu or so the manual for it says that i like my voodoo still:P but the thing is when i put it in my computer it either crases after sometime or just freezez and if it dont do that it keeps turning the screen black and then it comesback to what i was doing. it dont do that on my voodoo 4 at all

my psu is a KME 230w its all i have i am guessing its better than my 100w that i was forced to use since this darn computer killd two 300w psu's
