Power supply

Hello everyone, I have a quick question.

Ok so i have 2 graphics cards, one that clocks at 600watts and the other is 300watts. Do i need to get a 1000watt power supply to have them both work to increase gaming performance?

  1. what graphics cards are you talking about?

    i don't see what situation this could represent, but if you tell us your other system specs and exactly what two GPUs you are talking about, we can tell you.
  2. NVIDIA GeForce GTX 550 Ti - 1GB and Nvidia GeFore g210 are the two graphics cards i will have. Will i need a power supply that can accommodate both? if so, which one should i get?

    No you don't need a 1000 Watt PSU.

    The numbers you have quoted are probably manufacturers recommended specs and are over stated . The GTX 550 needs a single power cable and the other card does not need one at all.
    So i would say any decent PSU with a PCIE cable or two rated at around 34Amps should be good enough. I would look at something around 600 watts.

  4. You can run both of those and the rest of your system off a 400w power supply.
  5. If you want to objectively, accurately and scientifically determine what PSU power is required for your Vid card and PC in both watts and 12v rail amps., the forum Utility link below will show you how easy it is to calculate this information and objectively determine which PSUs are quality built, reliable PSUs that can meet your needs. Be advised that the available 12v rail amps. is just as important as the total PSU wattage. You need both to be correct.

  6. A good 400w unit would probably do it, but id get a 550w just to be extra sure. a corsair or xfx model would do the job nicely.
