I just finished my first build ever and everything has been going pretty well, except that the system is not registering my graphics card. After some searching, I think it might be that the Power Supply (an Antec Basiq 550W) is not providing enough amperage off the 12V rail to my Asus Radeon HD 7870. The card says that it requires 30A off the 12V rail, while the PSU box says it delivers 25A.
I have tried plugging in two PCIe power cords off of two separate 12V rails, but that led the system to not output any display info at all, although the LEDs above the power in plugs on the Graphics Card both show as green.
Is my diagnosis of the problem correct? Do I need a new PSU? Thanks!
