Just curious if two 6+2 pins is good enough for a 2080 ti and confirming the PCIe is 3.0?
Depends on the actual PSU in question really, those 2080Ti's are going to pull a lot of power so a high quality unit would be best to both run it stable and protect the investment. These things are going to cost quite a bit, some well over $1,000.
Personally I would go with a 750W PSU.
Seasonic Focus Plus
Corsair RMX
EVGA G2 or G3
Or one of the Seasonic Primes.
I would not risk a high end GPU on a budget PSU.
