Help! Radeon HD 4890 in a Dell Inspiron Desktop 545ST - Page 2

post #11 of 12
Am I reading this right, that you're using the Corsair PSU to power the 4890, and leaving the original PSU to run the rest of the system?

If so, try eliminating the older PSU and letting the Corsair run everything. I wonder if the card might be detecting voltage differences between the slot and the 8-pin connector, and shutting down to prevent damage.
