    Default Does my power supply affect the system performance especially my graphics card's perf

    Hi,

    My system specs is
    i5 6600k running 4.4ghz
    z170 A motherboard
    8GB ram
    gtx 980ti
    PSU: Seasonic evo m12 520W +80 bronze

    There are some "Rumors" that if a GPU wasn't able to get enough wattage from the PSU, It will not perform to its maximum capacity. How true is this?

    I almost believe on this rumor since I just recently upgraded my GTX1060 to GTX980 ti... suddenly there's no difference with the FPS results everytime that I play games like Battlefield 1. But when I run some benchmark test like the HeavenUnigine benchmark there's a huge difference between Gtx1060 and Gtx980ti when it comes to their scores (980ti wins) But like what I have said in games I got the same FPS as what gtx1060 provides me.

    during gaming sessions:
    CPU usage 100% / GPU usage 90% - 99% this is my status with my gtx 1060
    CPU usage 100% / GPU usage 50% - 80% this is my status with my gtx 980 ti

    So... Is there's something to do with my PSU since its only 520W (recommended system PSU wattage for 980ti is 600W) Does my PSU affects my GPU performance that's why its not performing like gtx1060 does?

    Thanks.

    A good 450W is already enough and a PSU can't affect the performance.

    That's literally impossible because PSUs don't work like that. If the system pulls too much power, it trips the PSU's safety circuits and it shuts off completely. There is no middle ground.

    Isn't the GTX 980 more powerful than the GTX 1060?
