Nucleo +5V pin only show 2.7V through SWD

I torn apart a Nucleo F446RE into ST-LINK V2 and i's STM32F446RE then connect it again through SWD with this configuration, except without serial TX, RX connected because I use it only for upload firmware.

For STM remote target programming with an Nucleo Board, I did some documentation here: http://www.radioshuttle.de/en/nucleo-st-link-interface-2/ Maybe this helps.
