Corsair SP2500 and ASRock Z87 Extreme compatibility?

[Nesdonal]

I am purchasing a ASRock Z87 Extreme4 ATX LGA1150, and already have a Corsair SP2500 sound system. I don't see RCA outputs, but see several other outputs. The ASRock boasts pretty decent onboard audio. Am I going to need to purchase a separate soundcard? The Corsair only supports RCA in.

Would something along the lines of the Rosewill RC-702 work well, or am I talking a separate $150+ soundcard?

Thanks in advance!

The Rock uses the Realtek 1150 audio chipset, so may want ot go with a sound card, might look att he Asus Xonar line of cards, very good, a number of my clients use/request them
