I agree with Mr. Prahlad, You're asking too much of your Mystic's 338W PSU. Also, Radeon 9800 Pro has a higher TDP than the GeForce4 Ti 4600 which was, if I remember it correctly, the higher-end video card intended for this line of Power Macs.
I would desist from upgrading the video card with that 9800 Pro, which nowadays shouldn't make so much of a difference, and go for another card with lower power consumption.
