And don't forget, many of the new vid cards need additional power. My PCI E
7800GT for one. And when I went to put it in, I was pleasantly surprised to
find a PCI E power cable from the power supply for just that.
I went with a 550w for this system. But then I run a dual core CPU, three
HDs, SCSI card, sound card, Zip drive, DAT tape drive, DVD...and of course
the vid card.
John is right. Buy for future needs. It never hurts to have too much power
in your PS, and they're not that much more expensive. It's better to error
on the side of too much power.
