I'm thinking about adding a new graphics card to my old Dell Optiplex 755. As it's a small case, I'm looking at 9800GT low profile or GTS 250 low profile. Here comes the *potential* problem.
I opened the case and found 1 PCI-e slot with marking (16,1) 25W which I think it's PCI-e x16, but the 25W really scared me. Does that mean it can only support 25W card? That means I cannot install that card though my PSU is rated 280W.
So it looks like adding a external power supply is a must. My question is: Will the card smart enough to pull the power from the external/secondary 6-PIN connector instead of the poor 25W slot?
Could someone please give me some advice. Thanks.
