When set to sync to the 12v mb control does it stay in that mode after a power cycle?

Yes it does stay in it's synchronized state after you sync it the first time. You won't have to constantly sync it after powering on your PC, if that's what you're worried about.

I have a mobo with at 4 pin 12v rgb header, i would like to connect a rgb gpu support bracket that needs a 5v 3 pin header. will this cable work? "

Yes. I had the same issue on My Asus board which has the older 4 pin standard

Can't git it to sync a teamgroup t-force delta ssd 3 pin with a asus b450 pulse 2 motherboard and it isn't working am missing something?

If you're trying to sync to motherboard connected devices, you're going to have to use software to sync it.

Is it possible to take off the 5v 3pins on the splitter?

I don't understand your question. The unit I bought came with a set of 3 cables. One allowed me to connect to an available 6 pin 12 volt socket on the MB. That power cable split into two leads. The larger lead was plugged into the Transfer hub. I think I connected my LED lights onto the smaller lead on that power cable. So, I have 2 unused small cables that were not connected into the Transfer Hub. One of those small cables is a 3 pin splitter that splits into three 3-pin leads. If you don't need to use that particular 3 pin splitter, don't connect it to the transformer hub. My LED lights slowly fade into different colors and that was good enough.
