A stacked electrical card connector assembly (1) includes an upper connector (10), a lower connector (20), and a transition-PCB (30) connecting with both the upper connector and the lower connector. The upper connector has an upper header (12) comprising an insulative main body (14) having a plurality of first signal contacts (15). The lower connector (2) has an insulative lower header (22), a metallic frame (24) having an opening (144), and a contact module (18) having a plurality of second signal contacts (182) receiving in the opening. The transition PCB has a first contacting portion (32) connected with the first and second signal contacts and a second contacting portion (34) connected with a mating connector (4).
