I have a X-connect PSU that i got about a year ago. Recently i somehow got my hands on a GTX 512. Whenever the card has to Render in 3D (ex games, ATI tool) you can seriously hear the fans sloowww down. PC probe 2 reports the 12v going from 12.03 to around 11.65 and somtimes dips to 11.58 which is below 5%. It is rated for a 34A 12v. Should i replace it and if i have to, any recommendations?
