Scaleo X - Is it possible to upgrade the graphic card?

[Nephitis]

Hello! I was wondering if my PSU can handle nVidia GeForce 8800 GTX

My Fujitsu-Siemens computer has the following specifications:

CPU: AMD Athlon 64 X2 5200+ AM2
Motherboard: Asus M2R-FVM
System RAM: 2048 MB (2GB) DDR2 PC2-4300 Dual Channel
Video/Graphiccard: ATI Radeon X1900 XT 512 MB
Sound: Creative Soundblaster X-Fi XtremeGamer Fatal1ty 7.1 + a front panel
Harddrive(s)/Storage: 2 x 250GB
Floppy drive: Yes
Media-reader: Yes
DVD-Roms: Yes, 2

This is already a quite powerful system that requires a PSU with good performance, and I was wondering if replacing the ATI Radeon X1900 XT graphic card with an nVidia 8800GTX graphic card will kill the PSU.

Thanks in advance!

You can open the computer case and have a look at the information given on your PSU directly regarding its capacity. Then compare with the power supply requirements for that graphics card.

There's a lable on the PSU that says "Do not exceeed 500 Watt". I don't know how good the PSU's are that Fujitsu Siemens Computer install in the computers they sell. My friend managed to run an nVidia GeForce 8800 GTS card (and I am thinking of getting this graphic card instead) on his system that runs on a 400 Watt Chieftec PSU, and the GFX card requires at least 450 Watt from a decent PSU.

I don't know how good my PSU from Fujitsu Siemens is compared to his PSU from Chieftec.
