You may have already done this, but try a different Molex connector
from the
power supply. Preferably one that is on it's own, not one that's the
2nd or
3rd on a chain. If you still get the message, install the card into a
different system and see what message you get there. It's possible the
card
is bad, but the more likely culprit is the ps.

Already tried both options and got the same results. I switched out the
350 watt PS that came with the tower for this 500 watt Rosewill and
have the same problem.
