Thanks for your advice, got the PSU swapped ready for the new case to arrive
Since the 600w has 2 rails, does it matter which PCI-E Power connector I use? It has 2 cables each with 2 x 8 Pins, one labeled GPU1 and the other GPU2. Doesn't seem to be anything on the box or in the book about which goes to which rail
Also, for the 3080 Ti on the 750w, it alright to use the daisy chained 8 pins? It requires 2 x 8 Pins. Or should I run 2 cables down from the PSU?
