Hello,

Which Corsair psu is better to use with the 3090ti and 4000 series cards?
HXi 1000 or 1200 watt or RMi 1000 watt?
 
Both are extremely good PSU's. But I suggest you go to the PSU forums. They have a list there of all power supplies and it will tell you if you will have problems. For example the PRIME Seasonic series will shutdown with the 3090 cards due to power surges. This is noted in the charts.

If you are determined to go 4000 series, I would wait for the new PSU's with the new power connectors to work around these power surge issues.
 
The HXi is supposed to be better than the RMi in terms of efficiency, but they are both high quality stuff. With the kind of power spike issues reported, I would be rather tempted towards that 1200w HXi just to be sure, specially with 4000 series. Or wait for the newer standard PSUs.
