Sorry, I'm not sure I understand your question. Maybe this link will help: https://steemit.com/faq.html#How_do_I_get_more_STEEM_Power.
You get rewarded in both SBD and steem power by default, and you also have the option to receive only Steem Power (SP) for your posts. Right now SBD are very pricey, so it's better to get SBD and to sell them for SP, rather than receive SP directly.
