How many watts should I have on PSU?

[Emultra]

There's a 430W power source that I think I'm gonna get.
Will it be enough for an Athlon64 Winchester 3200+ and a GeForce 6600GT PCIe?

How about overclocking?

 

[imported_whatever]

it depends on the psu. if it is a good quality psu, such as an antec, enermax, fortron etc, then it will be good for normal use and ok for overclocking. if it is a generic, stay away.

Agreed with whatever.
I'm using an Antec and I have no problem powering a whole bunch of hardware.

It's an Antec 430W.

That list on that site didn't have GF6600GT, so I selected 6800. Along with the rest of the stuff, it said I should have a minimum of 335W. I guess 430W will do. Thanks, guys.

Also bare in mind that its not just wattage that is important in PSU's. You want under/over current/voltage protection as well and these features are usually only found in the higher wattage models. An extra 20% on your purchase could save you a fortune in blown motherboard, cpu & ram. This would also have the added benifit of letting you add more devices later on without have to upgrade your PSU, also a good PSU is paramount to system stability

Would you say that the model I'm looking at will do that and do it well?

Nice Calc Tool...came up to 388, so my 485 "quality" PSU should be ok...
You should be fine with your setup and 430 quality watts, though...

Get a Kill-A-Watt meter and you will know exactly how much power you are using. Any electrical device plugs into it and it has a few measurements over time to determine your actual useage.

I got one off flebay for $25
