ITX Open Frame Custom build power help

[N0Class]

Here is a open frame itx build i am working on.

i7-9700k

32gb ram

300w sfx silverstone

amd pro wx7100

its pretty much done except the final touch. Power I am trying not to use the lenovo slim tip power brick. I have a 9700k in this and it power throttles. 

 

 

 

 

 

 

Some way i need to ger power from my sfx power supply to power usb c 

I went from trying to find a connector on the mother board 14 pin (DC_HDR) contacting lenovo parts directly (still no response). 

to buying this little guy 

 

I am just trying to figure out the best way to get power from the sfx psu to usb c thoughts or Any ideas?

not directly.  USB C outputs 20V for charging.

 

Your PSU caps at 12V.  You'd need a converter to go from 12 to 20, so...  not easy.
