Once you Shift, it's hard to go back

This is my first side-mounted cable PSU and I am not going back to the old school style. It makes it so much easier to manage cables before and after building. I swapped out my old 3090 for a new 5080 and if this was an old style PSU, I would have had to take out the entire PSU to swap out the power cables. Not with this side connector PSU.

This was an amazing deal on a solid psu. I like the shift element of this where the cables are accessible via the back panel. Much better cable management and setup .
