You need to see how much free power your computer & current power supply has available & how much power the card requires to run & to run efficiently.



You can email the card manufacturer & give them the tech specs of your computer/power supply & ask them if the card will work with your computer.|||Not usually necessary unless the wattage of your current one is too low. If it is say 350Watts or more it is suitable for most video cards.
