Yea that psu would work just fine. The one g-unit suggested is indeed better, but costs $40 more. Since you already bought the psu, it would not be worth it to ship it back and get another one.
At Newegg the base price of the CX600 is $69.99 before $20 MIR so the Seasonic is really only an extra $5.
