I have been frustrated for about a year and a half now trying to upgrade my video card in my Dell Gx260. I bought a card that I was looking forward to (Asus ATI 9600 perhaps?, don't quite remember) and I installed it and did not get a picture. I discovered over the course of the next week, that Dell Gx260's have a "proprietary" power supply which was not supplying my card with enough power. Even with everything disconnected from the power supply except what was needed to boot up, I could not get a picture.
I ended up discovering that an ATI 8500le and an ATI 9200se would work, so I have a 9200se installed now but I'm just not satisfied.
With only about 100 days left on my warranty, I have been tinkering around with upgrading the power supply. I know that pcpowercooling sells specific power supplies built for dell computers, but I was wondering if any other power sources would work? Do I risk frying my motherboard and other components?
Another complication is that the back of the case is not 'open,' which means the power supply can't have a power switch, or if it does I would need to cut a hole or something.
Does anyone have any experience here, or care to share words of wisdom?
thanks for your help!!
