I believe they are Molex Mini-Fit series but I can't find the exact match. Thanks.

Found an old thread. It points to some no-name connector, which is nice but I need a part I can specify in a design...

Here is the official Mini Fit (Jr) for PCI Express specification by Molex.

All part numbers officially compatible are listed in section 2.1.
