I want to upgrade my HP Pavilion p6-2002es to a better graphics card. Currently, the computer has an i3-2120 @ 65W and a Geforce GT 520 @ 29W. Will the 300W power supply handle a GTX 750?

Why does the Gigabyte GTX 750 @ 75W mention a 400W power supply recommendation while the ASUS GTX 750 @ 75W does not mention any recommendation?

Or will the 300W power supply limit me to the PNY GT 730 - 64bit 1GB DDR3 (fanless) @ 30W?

(Buying a new power supply is completely discarded.)

HP does not specify the power supply's name. Just that it is 300W.

It should be able to handle 300w if thats the rating. Your current total draw at the moment is probably less than 150w.
