I'm trying to keep my AGP rig alive since I can't drop $1000+ on a new one. I have a P4 3.0 GHZ HT, 1 GB DDR RAM, X800 Pro, 350 Watt PSU. I was thinking of getting a HIS Radeon HD 3650 AGP 512MB DDR2, 128-bit interface, 300 PSU minimum:

There is also a Sapphire HD 3650 AGP with the same RAM, interface, etc (there is also an HD 3650 AGP with DDR3 RAM as well) but requires a 550 Watt PSU minimum:

What's the deal with the two very drastically different power requirements? Is HIS underestimating and is Sapphire overestimating? ATI says it requires a 400 PSU and 550 for Crossfire:

Will I be able to run either the HIS or Sapphire versions of this card on my 350 Watt PSU?
