Well its brand new today, i used to have an antec 850w truepower quattro but it made very strange noises, i was given 2 of them both made screeching noises, but only the second made this noise in this topic that was unique to games. MY newest psu is an antec neo 650w, it ONLY makes a strange noise when gaming.

Which model, the one with teh big 120mm fan, or the one with the rear 80mm

Also what GTS the G92 or G80. If its the G92 then its pretty close to ultra.

its the neo with the rear 80mm fan, the gts was pny 512, thats all i know, thanks

Oh, yeah then it would have better scores. the 8800 GTS 512 is better than the ultra. its newer. As for the power supply, i would RMA it through Antec, and see if the replacement does the same

are you kidding me?, 400 pounds for an ultra, yet a 150 pound card is better... Sorry but i dont think so, if RMA means send it back and get a new one, i have already went through 3 new psu's and 2 have made the noise
