PSU for a System

[Ejhocky313]

I know there are a lot of threads like this on here but I just dont know which one I can relate to the most. I am planning on upograding my video card around christmas time, to a (PCI-EX.) EVGA NVidia 7800 GT, and I am migrating from a radeon 9800 Pro (AGP). I have an Antec True-Power 430 Watt right now, and my system is below. When I get the new Video card am I going to run into power issues? If so What wattage should I look for in a Power supply? I wont be adding anything else in the future, I pretty much have all I want/need.

Thank you for any advice

I researched this lately. I narrowed it down to two: Fortron and Seasonic. Seasonic is better but it's also more expensive. So, next time I want to build with a Fortron 500 watt.

I know I used a PSU calculator at extreme outervision and found my "simple" system could use a maximum of 330 watts. But your overclocked X2 might be what, 50 watts more and the 7800 GT about 40 watts more. Not all your gear will run at the same time so it's difficult to hit the max. But, if you attempt to overclock that video card, I think you're likely to run into trouble with a 430 watt PSU. Maybe 500 watts would be safer but a 600 watt model would be better if you want to overclock the video card.

I think you should be fine with your current PSU.

BtW: PCI-E and PCI-X are two different things. PCI-E is what new graphics cards use.
