[has22fas]

Out of these card's which take more power , my HD4870 has died and Sapphire are replacing it with a HD4890 does the HD4890 need a lot more power?

It draws 30W more higher than HD4870 and needs 2x6pin power connector.

What is your PSU? brand? model?
Well, HD4890 is faster than HD4870...

True^ 4890 consumes more power, but i think since your PSU handled a 4870 fine, it can handle a 4890 fine without any problems.
