I have been trying to get my x1950pro AGP to work for sometime. When I first had this card I had a problem with the fan not working. I had to rig it up to make the fan work. After I get it working I have problems installing drivers and once I have finally got drivers working I go and boot up some games and play them for like 4 hours. Everything is going good for 2 days, then I get my first crash while in a game. The card did this in every game, then I eventually start seeing artifacts in the games or on my desktop, lol. I went to sapphire forums and signed up, they told me it was my PSU 25 AMPS Max. That's where the ULTRA 550W X2-Connect Power Supply comes in. It is dual Rail 17 amps and 18 amps, which I thought would work for my x1950pro 512mb. It actually worked for a day before I started getting problems again, finally until my computer would not boot into windows but crashing way before that. Temps are very fine, actually below my old Geforce 6800gs I had which was always stable even at 98c. I have really tried everything possible except buying another new PSU. I was wondering if anyone has had this same PSU and same video card and has had luck?
