thanksYes.750 w is more than enough for single GPU if you don't have any extras in your computer.
thankshow would anyone know today? we haven't seen a test of any next gen GPU since...well... they were supposed to launch in more than 6 months, probably more taking covid-19 into account.
but yeah. 750W is way enough for a single GPU setup and I'd be very surprised if it suddenly wouldn't be anymore. that would mean your GPU would need to pull >450W. that's most likely not gonna happen.
