Yes. A minimum recommended 350W system power supply (with 12V current rating of 20A).

both of those cards should be fine if your 12 volt is prolly 17+ amps

17A are sufficient.... my psu have 18 or 19A with a 9600gt

Not sure. First, not all 400W PSUs are equal. There is a big difference between the one your using and the Corsair 400W. Seeing as you have a power hunger P4 and the PSU is several years old, it might not have enough to power higher draw cards. I'm not sure which of those two you listed draws the most. I'm also not sure which of the two cards you listed is faster.

If I was you, I'd figure out how many amps your PSU puts out on the 12V rail. Knock a couple off for the aged PSU, then buy a card that doesn't exceed that number. For example, if your 400W PSU has 17A on the 12V rail, don't get a card that needs more the 15A.

@ tarun 027: The 9400 will be no problem, but I am not sure of the 7900, it uses a lot more power and your CPU uses a lot of power as well.
Here is a list of cards, fastest at the top:

As for power requirements see here:

I would say look for the 9400/9500GT or even 9600GSO rather than a 7900, the older 7900 cards burn a lot of power for their performance and could cause problems if your powersupply is of poor quality and old.

Sorry mate but I have to question the validity of that power chart, it has the 7900GT @48w under load and SLI'd @98w and OC'd 8800GT's using less power than standard ones. Here's a link to help with the onging confusion surrounding how much power a Graphic card uses. ;)

@ Mousemonkey: I agree, some of the figures do look a little off, but, to date it's the most complete and accurate I have found.
Your link is also helpful but this whole subject seems to be getting out of hand with contradictory information abounding.
If anyone has a more accurate chart or source of information on the subject, please link to it!
