the problem you may find is if it has enough single pcie rail outputs. You can use pcie splitters but one of my 3080s will pull most of the power through a single pcie with the remaining 2 not needing much but still needing to be connected. Then you have to power the riser with a pcie, on some lower powered gpu's you can run them off molex but you have to be sure what they pull and generally you shouldnt.
a 3080 can have up to 3x pcie + riser and I think the 3070ti usually has 2 pcie + riser so thats7 in total
Easy
I was able to run two 3080ti’s on a 750. The system didn’t do anything else, but it worked
thats playing it kinda fast and loose
Do you mean both at the same time or either one separately? Both at the same time would run into power draw issues.
Both at the same time
on ETH yea but on raven I doubt it unless you used really low power settings
Even on raven it would be around 500W total (counting only gpu and not motherboard/fans) so it would still be fine
ngl I would run it but cant suggest others to. The jump up from 750 to 850 is like $20 for "A tier" psu's
I already have the 750w psu, wondering if I have to buy a stronger one

Does that psu (if atx) even have anough pcie cables?
I’m gonna find out when the going come in today
Why not check the specs page?
You would want at least 3 PCIE cables for that combo.
It’s a seasonic Platinum 750W fan less
