how can you tell the power supply of your pc graphics card. I have a windows XP, 2002 i think, and i have an nvidia geforce 7300, with a 300 watt power supply, but i need a new graphics card, and i wanted to upgrade to a 350 watt minumum required card. How can i tell if i can support that wattage?
What system is it?
What card are you thinking of?
What is the maximum airspeed velocity of an unladen Swallow?
Dell powersupplies have developed something of a ledgendary reputation for punching well above their Wattage, others do not
either you can search on google for the graphics card you were thinking of and check the TDP wattage which is the peak wattage the card will produce. Or you could go to the makers website (ati or nvidia) and check what powersupply wattage they recommend(but they always seems to overdo the wattage requirements),
you could also ask here if your psu will run your system with the specific graphics card you had in mind.
