gtx 970 SLI - barely any fps difference in-game

Hi,
Never know until it's under a lot of stress or you start overclocking it further before you might run into power shortages.

Recommended spec's are mostly to cover their asses I'd imagine but the gpu does soak it up not counting everything else
Never heard of your psu (Be quiet 750w 80+) "gold" I guess ?

Silent 730W PSU PURE POWER L8 | 730W CM supply by be quiet!
Using alphaniner's calculator it says im using 661 watts under full load, and reccomends a 750w power supply.

Hi,
Cutting it pretty close :)

Do you think that's the problem then?
Is there any way i can verify?
Can i connect just my second card to the power supply of my dad's pc if i put my pc next to it, or doesnt that work?

Hi,
Doesn't the second card already have separate power cables from the psu ?
Each card should have it's own cables.

Yes it does, but say that my current psu cannot give enough power to both cards - i should be able to see if that's the case if i connect 1 card to an entire different psu, right?

In general, using a second PSU to power certain components is a reasonable troubleshooting technique. But I'm not sure about using a different PSU to power each card in SLI. I doubt have no reason to assume it would cause harm, but it could potentially cause malfunction. If the second PSU has the juice and the connectors, I'd use it to power both GPUs.
