I am replacing a dead X1800XT with a new X1950XT
http://www.newegg.com/Product/Produc...82E16814241063

Both cards power requirements read the same although the X1800XT has
256meg memory vs. the X1950XT's 512.

My system ran fine with the X1800XT and a 450watt power supply (with 2
burners and 6 HDDs). Does the X1950XT need much more power? WHat
happens if the power supply is not large enough for the load? Any
possible damage to any components?

TIA
