Power Supply i'm think about:
http://www.newegg.com/Product/Product.asp?Item=N82E16817153023

So I've decided to swith GFX cards from my current 6600GT to a 6800GT. I also have a 3200+, 120GB SATA HD, DVD Burner, 3 fans and a cathode light. With my existing case power supply, I fear that it might fry something in my comptuer, becasue I assume it is pretty cheap, so I'm thinking about just getting this new one. Anyone that knows anything about power supplies and cases, please help me out.

seriously, you won't fry anything in your pc with a bad power supply.

the bad things that could happen are:

the power supply could die..which would obviously cause your computer to crash so possible 'data loss'
the pc could be unstable, because the video card is gobbling up too much power, which would cause cs or dod to crash, or have some video issues

in which case, you buy a new power supply

but if you don't mind blowing some cash, that power supply you list will probably be 'ok'

Not so Harkov. I have worked on ALOT of PC's where the power supply has fried. They always take something with it. Depending on what goes, usually a capacitor or two, the power supply spikes taking things with it. I have had it take motherboard(common) sometimes hard drives and even CPU's. As a matter of fact I have my sisters computer sitting in front of me that the PSU went and the motherboard fried.

When looking for a power supply, try to get as much Amps as you can get from the 12V and 5V side. that PSU you showed has 18V on the 12V side, which is respectable. Also something to look for is a power supply with PCIex connectors incase you upgrade, but you might pay more for it.

I personally like the modular power supplies. You can connect just what you want withour having all the connector hanging around your box doing nothing.

So would the power supply that I listed be fine... would I still be able to upgrade to that 6800GT and maybe even further... possibly a 3500+???

as Widow points out, yes a PSU can take goodies with it if it fries out (or even if the case you have it connected to grounds out poorly, which kills anything in the AGP/PCI/PCI-e slots). Thermaltake makes good PSUs (I have 2 whispers myself) but I wholly recommend any True Power Antecs. Sure you pay a bit more (upwards of $100 usf) but damnit if theyre not worth it.
Heres one for $20 more than you put up: http://www.newegg.com/Product/Product.asp?Item=N82E16817103928

Still kind of expensive. This would only be for the 6800 GT I'm adding... but the one I showed is such a good deal rebate and everything. It should be more than enough right?

Totally agree with Widow on this one. The power supply should be the most reliable piece of your system. Most computer problems are caused by PSU failure/poor operation voltages.

Generally speaking, you get what you pay for. Cheap PSUs give crappy voltage tolerances, and usually low amps on the +12V rail. Go with something made by Antec, Enermax, Fortran (OCZ.)

That power supply will do what you need it to do. But what else do you have in the system. Not just vid card and cpu that runs.

How many hard drives?
How many CD ROMS/Writers?
Floppy??
PCI cards??
How many Fans?
Any Lights??

Gotta put into account everything that uses power on the system. Processors are easy to power, they only take 1.35+ volts as well as 2.35+ volts for the ram. Sure that power supply will power what you want with any processor you put in it. Just let us know what else you have for power consumption.

Is this sytem AGP or PCIex? Will you run an SLI setup in the future? If you want to, that power supply has only one PCIex connector. You would need an adapter for another card.

i had to get a power supply a few years back and got the antec true power 430. it has held up well. but it don't really have a stellar system. amd 2800, 1GB 3200, 9800 pro, 80GBide, sblive5.1 and a pioneer dvr-108. the 430 is plenty for just that. but one thing i saw recently that i think is genius is this new dual core 7800's. check the pic here, it has a f'n power brick for you so you don't have to worry so much about your internal power supply. f'n genius i tell ya.

I have one 120 GB SATA HD... One DVD Writer... a floppy, no PCI cards except for my GFX card (dont even think that counts), ugh two 90mm and one 120mm fans, and one cathode light. It's  PCI-e system also

[Poops Mcgee]

the 430 should be fine for just that much. but if i were you, i would wait until the next gen of nvidia comes out and the price on the 7800's start to drop and get one of those.
