I need some help here guys. I got my angled sata cables in today, got the card installed, but when I boot up.... no display at all. I uninstalled all the old NVidia drivers. I even downloaded and installed the latest drivers for the 5830. When I put it back in and booted again.. no display at all, but the fan is spinning. Am I missing something here? Is the card junk? Is the Raidmax 530w PSU not enough? I'm about to go apeshit crazy here.
Newer video cards require separate power cables to be plugged into them.
Check the manual for the card to see what your power cable options are and plug those cables in.
Also check the power requirements for your card.
A quick google search shows that your card uses about 350W which means you have about 200W overhead for all your PC's other components.
