My mom got a dell pc over a year ago and it came with a 8800gtx. The card was not working to well so i opened up the pc and blew a bunch of dust out and got it working a bit better. It is still not running anywhere close to what a 8800 should (even older games like HL2 give it problems if it is on for more than 30 min) so i looked for the problem and realized it is the PSU.
Dell put a 375w psu in this pc. I know a lot of people go overkill on their psu but i also know you need at very minimum a 450w psu to run a 8800gtx. Also the way dell built this pc is backwords. The right side (from front view) is the side that opens up and the fan on the 8800 is facing up. There is no rear exit fan in the case and only 1 fan blowing into the pc, but that is the heatsynks fan. This card idles at 83 degrees celcius and when i put fc2 in it bounces up to 99 degrees within minutes and the shader stops working properly (don't know if that is from lack of power or overheating)
Today i am going to go and get 2 80mm fans and mod them into the case. The rear of the case doesn't even have holes to put a fan in. Honestly though i am worried about putting even just 2 more fans in with the psu already being taxed so hard.
I was curious as to if anyone knows of a 5.25 inch add on psu that might help me out, or any other product/solution. It would have to have the 2 6pin connectors for the 8800 and be available to Canada. So like NCIX, Newegg, or tigerdirect. Getting a brand new PSU is not an option either because the only psu that will fit in this case has to be a dell psu.
There is a pic of the dell i am talking about incase it helps.
