Ok strange question but here goes. I am getting a new PSU and graphics card. I believe that some cards require a separate/extra electrical plug, yes? I mean some cards just snap into the pci slot and then some other cards do that but also have a separate power plug. I don't know how else to word it. My question is, how do you know before ordering the card if it take a separate plug because some reviews I have read mention that the purchaser then had to order a six pin plug or something and wish they had known that when they ordered the card.
