Video cards and PCI compatibility

Specs: Windows XP
I am looking to upgrade my Dell Dimension 8400's video card, a GeForce 6800. I am wondering if the PCI slot it has (express X16) is compatible with PCI express 2.0 at all? I was looking at a Zotac 9600 GT and if I recall correctly it stated it was backwards compatible. Any help on this is appreciated and suggestions are welcome. Thank you.

PCI-e X16 2.0 cards are backwards compatible with PCI-e x16 1.x slots.

You need to look into your PSU's possible that your 350W? unit won't be able to handle the load of the 9600GT. The amount of amperage on the +12v rail is critical. You may wanna play it safe & get a Radeon HD4670 instead. It's a decent gaming card with extremely low power requirements.

Thanks for clearing that up for me. The PSU was/is a concern, but I keep finding threads that they are generally under-rated. Thanks for the suggestion on the video card. Any suggestions for an nVidia chipset card?

"The PSU was/is a concern, but I keep finding threads that they are generally under-rated"

You have to take any info posted in a forum with a grain of salt. There's a LOT of misinformation out there & a lot of idiots that continually spew it out without ever verifying if it's correct or not. If it's not backed up with some sort of proof, be suspicious.


How so? As in a 500W unit being marketed as a 350W unit? Why would a manufacturer do that? The PSU is arguably THE most important piece of hardware in a PC...every single component depends on it. If your PSU is underpowered, you'll experience random shutdowns at least, complete system failure with fried components at worst.

"Any suggestions for an nVidia chipset card?"

No, not without knowing your PSU specs. I'd need to know the brand name, the wattage, the amperage specs for the +3.3v, +5v & +12v rails. The HD4670 will work with your current PSU...anything else is a gamble.

This has a pretty good picture of the power supply and its specs if that helps out. Thanks for the information.

Your link doesn't work. Would it have been too much trouble to copy/paste the specs?

Probably even less work to make sure the link worked in the first place as the specs were listed in a picture of the label on the power supply:

+5V ~ 22A
+5V(FP) ~ 2A
+12V-A ~ 18A
-12V ~ 1A
+3.3V ~ 17A
+12V-B ~18A
