Can i run a gtx 1060 6gb and a gtx 750 ti with 700w?

So my main is the 1060 but my brother had the 750 ti laying around so i decide to use it for a dedicated physx card and i need to know if 700 w is enough

    Assuming your GTX 1060 is a brand/model that requires an 8-pin PCIE power connector (some only requires 6-pin) and your GTX 750 Ti is a brand/model that requires a 6-pin PCIE power connector (some does not require this), the max. theoretical power draw of these GPUs would be:

    GTX 1060: 75W (from PCIe x16 slot) + 150W (from 8-pin) = 225W
    GTX 750 Ti: 75W (from PCIe x16 slot) + 75W (from 6-pin) = 150W
    TOTAL for 2 GPUs = 375W (theoretical power draw, but, actual draw would be lesser)

    Now you did not mention any of your other specs.

    Assuming, again, you have an overclockable CPU, an i7 (i7-7700K), which has a TDP of 91W, but can reach ~120W if OC'd. RAM, for instance, 4 sets of DDR4, would be ~25W. An HDD and an SSD, roughly another ~25W. So, that's 170W total on your other components (assumed only).

    You *might* (due to assumptions) be looking around ~545W power draw for your system (+12V).

    Depending on the specifications of your 700W PSU's max. amps/watts at it +12V, generally, it should be enough.

    700W power supply should be more than sufficient unless you have an insane amount of perifs that are drawing lots of power.
  3. 500W or less is what you need. 700 is way too much.
  4. MeesterYellow, there is no problem with a PSU that can handle more than what it will be used for.
    All the PSU has to do is supply the required power to all the components, so with less % load it should last longer.
    Besides, REV____ already has the 700w PSU so why would he change it?

    To save money. Plus, it's better to have a more efficient PSU than one with more wattage than you need.
  6. OP just wanted to know if 700w is enough. Seems to me that he already has the PSU and wasn't looking for purchasing advice.
  7. I know, I just gave my opinion on what he needs.
