Good afternoon, I want to add three more SSDs to my T5820 configuration, I must say that I already have the 4 front HDD trays full.

I have opened the workstation and I see that I have 2 SATA ports and 1 ODD port free, my idea is to buy an IciDock caddy to put it in the place of the 5.25 bay, this: https://www.icydock.com/goods.php?id=230

Well, I ask for help in the following, I can buy the SATA cables without any problem, but I have no idea how to power the drives, my power source is 950W and I have seen that there is a free connector similar to this one:

I can't, and don't want to experiment with power issues because I'm afraid of burning the board. Does anyone have an idea what type of cable I should use to power 3 SSDs, for a total of 7 SATA drives?

There is also a connector near my video card, but in the future I plan to replace the Quadro P2000 with the Quadro "Ampere".

Thank you very much.
