No new cards. power supply should still be good but ya never know. we do have a spare power supply and cabinet 1 so we could try to swap that, but I am in a hospital enviroment and cant take the system down on just to try it.
oops forgot about the power factor thing. We have been wanting some one to analyize our system and look at the power factors and also see if we could reorginize the configuration to get some 16 port cards in and some more analog lines as well.
