Gen7 - Molex connectors

Hi all. I have a question about the Molex connectors for the power supply on Gen7 v1.3 board (connectors marked "CONN2" and "CONN3" on this schematic).

The headers on the board itself are ones I got in a components package along with the other connectors. I'm connecting an ATX power supply to these connectors, and have experienced a lot of frustration trying to attach/remove the cables. They are extremely difficult to remove. Every time I try to connect or disconnect the cable, I have to worry about damage the solder joints on the pins.

Are there variations on these connector types? Do different ATX power supplies have slightly different molex connectors?

Yes, these connectors require quite some force sometimes. Just like in PCs. I think things get a bit better if you put some Vaseline/petroleum jelly where the plastics housings meet.

You can also sand/cut away the snaps on the connector. They're there, even if not obvious. Two on each of the longer sides.
