Thermaltake 1050 RGB PSU has a weird 24 Pin Conn

[saquist]

I have the Toughpower Thermaltake 1050 RGB and the 24pin cable is confusing me. I don't know which end goes into the mother board and which end goes into the power supply.
On Both Ends have 24pins but one end has an 10 pin connector ON THE SAME CABLE. Can some one help?

They are keyed differently, so side that fits.......
