Hi, I recently built a new Computer and after putting it together there is nothing showing up on the monitor. it reads Monitor in power save mode. I overlooked my Graphics card and PowerSupply. On the Graphics card it says Minimum requirements to be 350w PSU with a minimum of 20 amps on the +12 volt rail. On the PSU that i have ( came with the case) it reads Dual 500w and in the DC = max output section, that on +12v1 = 8A and under +12v2 = 14A. So unless you add these two together, I Wouldn't have enough Amps flowing to the Video Card, Causing the blank screen on the monitor, correct? Its from my understanding this is correct, and since they told me at the store that the PSU in the case would be good enough for the videocard, they should be able to replace the PSU or refund my money for the case, right?
