Upgrading from Radeon 5830 to GTX 760, is my power supply good enough?

Currently running a 530 watts, Rosewill Green series PSU

Both the Radeon 5830 and GTX 760 listed a minimum of 500 watts needed, do I need to upgrade my PSU? (I can't find the exact power needed for both graphic cards)

  1. It's one of the later Rosewill units, not up to Seasonic standards perhaps but plenty enough for a single GTX760.

    Thanks for the quick reply. Sorry to be a bit paranoid but is it a guarantee that my PSU will definitely be enough a GTX 760? The PSU has been running perfectly on my 5830 for almost 2 years btw
  3. GTX 760 :

    Measured power consumption single card =
    1.System in IDLE = 121 W
    2.System Wattage with GPU in FULL Stress = 279W
    3.Difference (GPU load) = 158W
    4.Add average IDLE wattage ~10W
    5.Subjective obtained GPU power consumption = ~ 168 Watts

    GeForce GTX 760 - On your average system the card requires you to have a 550 Watt power supply unit.

    Radeon 5830 :

    •System in IDLE = 176 Watts
    •System with GPU in FULL Stress = 325 Watts

    The monitoring device is reporting a maximum system wattage peak at roughly 325~350 Watts

    •The card requires you to have a 500 Watt power supply unit at minimum if you use it in a high-end system. That power supply needs to have (in total accumulated) at least 35~40 Amps available on the +12 volts rails.

    The PSU of yours is a Tier 2 Brands quality, so the conclusion is, it can run GTX 760.
  4. You should be fine with that PSU, it meats the minimum wattage for the 760 and should have plenty of power on the +12V rail because it's already built for multiple GPU support.

    Relax, you'll be fine, mate! If I was in any doubt I'd have already suggested you change the unit.
