recommendation?

I just ordered an ATi Radeon x1900xtx.

according to the dell users guide for my computer:

http://www.arieldesign.com/download...r supply in a dell precision workstation 370"

350 Watts Power Factor Correcting
(PFC) power supply

Graphics cards up to 150 watts are supported.

Newegg says the GPU requires a 450 Watt PSU, but i wonder if my PSU will run my new card (it's still being shipped) without any upgrading.

thank you

i wud say that wasnt enough tbh, although im not 100% sure. somewhere around 450 is the minimum i wud say. But i cud be wrong

The Watt rating isn't the whole truth, usually a card has a specific minimum +12V rating, for example a card could have this as the minimum: +12V 25A. Which means that the sum of all +12V rails has to be 25A or higher for the system to run stable with a high load. Antec make nice PSU's, but there are a lot of other good brands, too. Just don't buy a cheap PSU, they usually aren't very reliable or powerful even if the Watt rating itself is high, that is usually just the "abnormal peak" rating they've used. By this I mean that the effect in % of the PSU should be quite high, cause there are PSU's that have a rating of 450W but can only get close to that when a sudden peak occurs and not the whole time, like you'd want it to.
