PSU question

I am building a new PC around a DFI Lanparty Ultra-D mobo.
I bought a Thermaltake W0009RUC Silent PurePower 420W PSU for it.
All the parts have already been shipped and I cant make any changes now.
I wonder if anyone knows if this PSU has a 24pin connector or not. If it doesn’t, I’m screwed, and I’ll have to go buy a converter.
Also I need to know if these converters are sold in regular computer stores, or they can only be bought online.

according to it’s specs the retail box has a 20-24 pin adapter included.

Oh, thank you! Sheesh, I feel so much better now. That damn thing got me concerned.
