Will GK400RB support two PS210 cabs?

[Signs]

I have an Epifani PS210 8 ohm cab, and need a head. One of my new TB buddies will make me a sweet deal on a GK400RB head. My question is, will this eventually support a second PS210 or do I need to get a more powerful amp head?
My funds are kind of tight at the moment, so I may still buy the amp, I would just like to know for sure if I will have to upgrade it to run a second cab.

Yes, 2 8 ohm cabs present a 4 ohm load, and that amp will run all day at 4 ohms.
