it looks like that Dell has a 250W PSU, but includes a P4 1.8Ghz, 40gb HDD, and 512MB of RAM. A rough calculation shows approximately 166watts required (not knowing extras or which P4), and assuming your PSU has 80% efficiency (which is not a given), that puts you at about 200Watts…meaning you should EASILY have enough headroom for that card which shouldn’t be more than 8-10watts.
If my numbers are correct 🙂 it won’t hurt to try. if it’s not enough, it just won’t power up!
