Hey there, I have something I believe you're looking for. I cannot think of the model off the top of my head (cards at my office) but it's an Nvidia (no power req) with decent specs and only a couple of years old. I'll get the model # as soon as soon as I get back to the shop but it's right around the same form factor as a 5450.
Thanks for the reply, I appreciate it. Unfortunately, I don't think I'll be needing a card like this anymore, and I forgot to lock this thread.
However if I'm ever needing a low power card in the near future I'll send you a PM.
