[SOLVED] Is 300W enough?

Solution
If the card is ONLY slot powered, and requires no additional auxiliary PCIe power connection, then that PSU is "probably" ok, as far as capacity is concerned.

As far as quality? Meh. Probably not the worst of the OEM possibilities, but who knows. If it's been in service a while it could be affected by the addition of a new graphics card, even a slot powered one, but generally it's probably ok so long as it's still in good shape.

If any of the cards you are considering require auxiliary power, you will want a new PSU.

In any case, if that PSU has some miles on it, AND you are going to add a new graphics card, it would not be the worst idea in the world just to replace it for GP.

If that is a proprietary model, well, good luck with that.
