Ok so i'm trying to put in a XFX R7800 into my pc. My mobo is MSI B75-P45, PSU is Raidmax 450 max watt. Now the issue i'm having is when i install the Graphic card i get no image and my screens stay black, i'm wondering if the PSU doesn't have the power for this card or due i need to hookup the PSU direct to GPU. The graphic card cooling fans do turn on.
Thanks to all in advance
