Im rather new, but I was wondering if I could get some help with upgrading my video card. I have a dell xps 400, and It has a Nvidia 7300 LE in it. Im looking to put a Nvidia 8800GT in it. My question is, can the PSU in it hold it? I asked dell, they didnt help much. I tried another forum, thye narrowed it down a little for me, but didn't quite work. Im about 90% sure its a ATX (what ever atx is ) 375W PSU, and I have come a conclusion... I want to run my games on half decent settings without lagging.
I also need to upgrade my ram.... but I can do that later when I get some more money.
How many amps does it have on its +12V rail(s)? I suspect that without a PSU upgrade, the best you could do safely is put an 8600GTS in it for a big jump over the 7300LE. What games do you want to play, and at what resolution?
There should be a label on the PSU describing the rails and amperage. It may be a little table, or just text, listing various voltages and their outputs. Voltages should include +3.3V, +5V, +12V, and -12V. There may also be -5V and +5VSB. Unlikely on a 375W PSU, the +12V may instead be +12V1 and +12V2.
2) If you are going to get the 8800 GT, do not get the 256 MB version. The 512 MB version is notably better.
3) If I may ask, what kind of processor do you have? Most XPS 400s seem to have Pentium Ds. The reason why I am asking is simply because a 8800 GT and a low or even middle/high range Pentium D might not be the best combination. In other words, a weak processor might significantly prevent you from tapping into the 8800 GT's true power. If this is the case, something cheaper, but still reasonably powerful (like a 9600 GSO or HD 3850), might be a better option.
Sorry about jumping the gun a bit, I am just trying to prevent any future disappointment.
Note: Because you presumably own an XPS 400 powered by a Dell motherboard, the only processor you could upgrade to without changing your motherboard and case (and possibly power supply) would be another Pentium D NOT a Core 2.
