24 to 8 pin adapter Inspiron 3670, 3650 old topic revisited

moddiy sells the same sku CAB359 adapter for 3670, 3650, and Optiplex 9020 as well as 7040, which is evidence that the Dell 8 pin pinout is the same across these models.  there are vostro desktops of 8 pin on motherboard likely of same pinout too.

users who want to upgrade 3670 3650 psu to have a 6 pin for gpu can choose either Dell Optiplex XE2 MT oem 365w psu, or a standard 24/4 pin ATX psu plus the 24 to 8 pin adapter.
