BambiBoomZ,
Not to hijack the thread, but would the 600W PSU in the Z420 have enough power to drive the RTX 3070 when combined with the Xeon E5-1650 v2? I ask as I have a 1070 Ti currently combined with that CPU and it seems to struggle driving both under heavy workloads -- would the 700W power supply from a Z440 potentially work in a Z420 perhaps?
