Corsair HX750i low 12v?

Hi folks,

My HX750i 12v rail goes down to 11.9v under load using at 6700K and RX580. I found this very disappointing as my older AX760 and even my RM1000 are rock solid at 12v

All the HX750i reviews I have seen say that the 12v is very solid, do I have a bad PSU? I am thinking to replace it with the older AX760!

Not ideal but it's well within tolerance (+/- 5%).

11.400v is the lowest allowed so it's well within tolerance. I take it you are reading this from software which is not the best way to read voltages? Reviews will be using hardware to monitor the rails and if you don't have a super expensive testing rig a multimeter will do the same job. Anyway, it's nothing to worry about.
