If i bought a graphics card with a power cord, cable, plug thingy, will it matter how much power my desktop can produce? Because i know some graphics card use quite abit of power and my desktop is old and does very little power.. So yeah.
With a power cord, cable, plug thingy? I've never seen such a setup, and I thought I knew a bit about computers. I know I've seen old (mid 2000s) articles about something like that, but it never got market traction as far as I'm aware. I'd say that you would have to replace your power supply - but I guess a separate power supply should be another solution as well - though it might actually be cheaper to replace the power supply rather than having a separate power supply for your GPU. Also, your motherboard doesn't necessarily support the newest GPUs at any rate, so... yeah.
yes if the graphics card needs more power than that it already gets from a motherboard, you will most likely need a power supply that
It will be pci-e power connector(6or8pin) and should be connected, depend on the card as to how much power it requires, google your card numbers tdp it will tell you the max wattage of the card, best to have a supply with 250w + the cards wattage at least
