Modular PSU - additional SATA connectors?

[RedNova]

I'm awaiting delivery of a SilverStone ST50EF-PLUS-SC PSU and I want to add two additional SATA power connectors to it. Is it possible to use the Enermax Modular Cable (EMC001 3 x SATA) with the SilverStone PSU? I've never built a system with a modular PSU before so this is all new territory for me.
