nope 300watt
Take from the Manufacturors site:
"This Graphics Card Requires:
1. A minimum 300W system power supply
2. An AGP 2.0 (or higher) compliant motherboard. Some motherboards violate the AGP specification and therefore this card may not physically fit in some systems.
3. An available hard disk drive power dongle (smaller floppy disk drive connector is not sufficient)."
