How much watts does the Logitech z623 2.1 speaker system uses?

[Vengeful Veteran]

I'm planning to build my own rig by the end of this year and I was thinking of getting a 2.1 sound system and I came up with the Logitech Z623. So, I was wondering, how much power does it consume?

Other than that, I'll be using a ASUS Xonar Essence STX sound card. Does it draw power too? If so, how much would it be altogether? I'm afraid that I won't have enough power to supply the components.

The sound card will draw power from the PSU but I highly doubt it'll be more than 5-20 watts.

The Logitech kit is self powered, so you aren't powering it with your computer, just need an open wall socket.
