Is it ok to try and run this card with a less then required power supp

It may depend on the quality of your PSU and how many amps it delivers on the 12v rails. Similar cards need 18a, so I suspect you are short. You may not damage the card, but if it does not work, then you will have cost you something to return it.

I would look for another solution.

I highly doubt it needs a 250W PSU, the specified maximum power for a PCI device is 25W over the PCI Bus. Since the card doesn't have an external power connector, it won't take more then that. Depends on what is in your system then, as to if you have 25W left over, also depends on the quality of the 250W PSU.
