2 x 1950XTX Crossfire - PSU requirements

[UltimaBoB]

I've been having problems with my 1950XTX crossfire setup.

Some have suggested that an Enermax 620 watt PSU has een too weak and that if it has dropped any output over its life, I now lack power for the cards.

How much power do XTXs take?

They take 230watts full load in crossfire.
Your Enemax is a Liberty version 620 watt? If so it has 2 -22 amp 12v+ rails which should more than enough to power them cards.
