Will a 6+2-pin PCI-E plug work in place of an 8-pin EPS12V plug?

The motherboard I'm looking to get has a 24pin and 2x 8pin connectors on it. The power supply has a 24pin, 8pin, 4pin, 6pin and a 6+2pin connector. Will this work correctly or should I look for a power supply with 2x 8pin connectors on it?
