Hello,
i want to use a second GTX 980 SC with my EVGA Supernova G2 750W PSU.

This is the rest of my system:
CPU: Intel i7 5820k (no OC)
RAM: 4x4 DDR4
SOUND: Asus Essence STX II (~20 Watts)

Do you think the PSU will be sufficient at full system load?

    two 980 here with 730w psu all day long.
    each 980 eats 185w under maximum load.

    CPU: i9-7920X || Motherboard: ASUS WS X299-PRO || RAM: 4x 4GB Kingston DDR4 3200+
    GPU: EVGA GeForce RTX 2080 XC ULTRA HDD: 2x Samsung 960 EVO NVMe 250GB - RAID 0 & 2x Kingston A400 480GB
    PSU: Cooler Master V750

    I think it will be just fine, you should peak around 500W without OC.
    GTX980 SC has 165W TDP and Intel i7 5820k has 140W, total of 470W in SLI.
    so you're good.

    You can reference graphics card compatibility chart at www.evga.com/psu/ to take the guesswork out. Referencing this, you can even use one of the EVGA 650 gold rated power supplies to power two GTX 980's.
     
    The 750w G2 will work fine. The 750w B1 does have three PCIE power connectors, so you will want choose a B2, or gold rated PSU since the GTX 980's need two power connectors each.
