Assuming that the 5870 pulls at least 150W: 150W x 3 = 450W This is only on the 12V rail, which most likely your 550W psu could only produce lower than 450W. You probably need at least 750W to power the whole thing. dharmdev January 31, 2011 5:39:54 AM ok i put 1000w coolermaster and tell u agen thanx for help Can't find your answer ? Ask !
