Do I need more power?

[Magnulus]

My current system:

430 Watt Antec True Power 2.0
Athlon X2 3800
GeForce 6600 GT
3 7800 RPM hard disks
1 DVD-ROM drive
1 Creative X-Fi sound card

I will be upgrading the graphics card to a GeForce 7800 GT. My question is, do I need a bigger power supply, assuming I am not overclocking anything?

Probably not, although i don't think the truepower is well designed for current generation systems, where there is a very high load on the 12v rail. It should be ok.

I think the 7800 range draw less power than the 6800 range btw. It's not a huge increase in power draw.

You should be fine. You can always have a look here: http://www.extreme.outervision.com/index.jsp It gives you a decent indication of how much power you'll need.
