Hi, just been given a Radeon X1900GT graphics card and would like to install it in my PC. Using on-board graphics at the moment. Will my PSU handle it or can I just get a small dedicated PSU for the card? I'm not a gamer so speed doesn't matter. I would just like to use two monitors for my Sonar recording software ( tracks on one and effects on the other) and possibly Autocad, maybe Photoshop - don't really know the full possibilities until I start using them. I have a home built PC with a 400w psu. It is powering the following:
Asus M4A78LT-M motherboard with AMD Athlon 2 x4 645
2 x 500GB hard drives
2 x DVD/CD re-writers
Echo Midi Mia soundcard
Hauppauge Win-TVR PVR PCI 2
2 x PCI usb x 4 cards (not all sockets in use)
I'm using Windows XP Professional.

Should I find the power consumption of everything in my PC and see how close it is to the 400w psu?

Any advice would be welcome.
 
That graphics card will consume around 75watts ... I roughly calculate your system would need around 350watts ... I'd run it, but I'd also be aware of the possible limitations.

You would need to replace, not add a second PSU, if you wished to provide a better overhead.

Thanks. Probably a good idea to upgrade to, say, a 500w psu. That should give me a bit of leeway.
