well over 500 watts as well for assurance would scoff at 700 if you plan

I have an HP desktop computer model m1090n (3.6GHz, upgraded to 3GB ram)
on which my video card has gone bad. I am considering replacing it with a
much more powerful card, perhaps the eVGA GEFORCE 7950 GX2. My question
concerns the power supply requirements.

My computer currently has a 300w power supply. Will that be adequate to
run the new video card? In general, if the specs for a particular video
card state that it requires a 350w power supply, and I have a 300w power
supply, what will happen? Will the computer not boot at all, run slower,
etc.?

I could change the power supply, but it is a hassle and I would prefer to
avoid it, if possible.




A generic 300w will not do. I have a pretty good 420w with excellent amp
ratings, but even I'm not sure a 7950 GX2 would run reliably with all the
drives and a more powerful CPU hooked up. You don't want to risk damaging
your expensive new card with a generic PSU with irregular voltage, so get
something decent with PFC and good 5v and 12v amp ratings.

Anything SLI certified and PFC should be a very good match.
