I have it plugged in and it seems to be running fine but if this computer is a very light use will it cause any problems.

EDIT: I guess the required PSU is 300W. So I'm just wondering if running it 50W under if there will be any ill effects.

Yes there can be affects, it may not be shown at first, but it will kill the computer faster. A video card like yours is defently power demanding and to get the best out of it, you need that power. I would go even a little higher than 300W since it can't hurt to have more, only less. I also had a factory hp desktop, very basic and it used 250W psu so I'm not sure how you are getting your computer to work off that.

A PCIE_x16 cards needs 26 amps on the 12v rail if the PSU has multi rails you need to increase the wattage because 1 rail will be dedicated to the CPU and you want to run in the 60-80% load range to keep heat down so your really looking at a minimum closer to 550w-600w in a quality unit
