The new RX 580 Series will have a 6+8 Pin power connector.

This is going to be a problem to connect to most PSU's.

Thats 6x6 pin + 6x8 pin connectors.

Which PSU has those? My favourite HX1200W and Evga G2 1300W cant connect that many cards...

EDIT: Evga G2 1300W can in fact connect those.

Anyway, be carefull if ur buying PSU's for the RX 580 rigs
