I dont really know if in this case you can cash out fromFT However you can retransfer to PS and then you cash out.
Please note that in order to withdraw funds from your Full Tilt Poker account, you must have previously made at least one successful real-money deposit. Also, for security reasons, withdrawals will not be approved to new payment method accounts until at least one deposit has been made to Full Tilt Poker using that account. This does not apply to Local Bank Transfers or Check Withdrawals.
Here is your answer
