change psu to one that has enough support for the TR motherboards power needs
to be quite fair the sales webpage and details do clearly show you what psu would be needed when designing your new system build

a fast/simple option would be to buy a cpu/eps splitter plug

autoleads do many versions and can be found on amazon

You definitely need the 4 pin connector plugged in.  Please read this thread:

welll im not exactly sure if its optional or not
but few years ago there was only 24pin for cpu and pci devices
with introduction of pentium4 (power hungry cpu at that time) extra 4pin was needed (24+4)
with introduction of pci-express another 4pin got added as wattege over pci-e is higher than on pci (24+8)
and threadripper just happens that it has one more cpu to feed (24+12)
so up to you if its optional :)

That 4 pin port on the top left is for VRM per ASROCK. I am not exactly sure what that does.  I read somewhere powering that port is optional and in other places it is a must.  So I am not sure what to make of it.  I would like to hear it directly from ASRock.  

The 6 pin PCI-e port you are referring to is on the right side next to the SATA ports. I need to power it only when I use more than one GPU, I think.

Considering the TX850m is little higher than their mainstream PSUs, I am surprised Corsair didn't include an extra 8 pin CPU cable or even 4 pin but they packed plenty of SATA cables than I care.  Soon all of my storage will be M.2 based.

There are EPS12V splitter cables. Get one of these. Your PSU should be able to handle the load, even if you decide to OC.

rocker76177617, please don't leave it unpowered.  I suspect that VRAM is Voltage for RAM.  You need a more modern power supply.  Enjoy, John.]]> Wed, 10 Jan 2018 02:19:40 +0000 https://forum.asrock.com/forum_posts.asp?TID=7236&PID=42681&title=x399-taichi-4pin-cpu-power-connector#42681 <![CDATA[X399 Taichi 4-pin CPU power connector : My new Corsair TX850m PSU didn&#039;t...]]> https://forum.asrock.com/forum_posts.asp?TID=7236&PID=42679&title=x399-taichi-4pin-cpu-power-connector#42679 Author: rocker76177617

My new Corsair TX850m PSU didn't come with the extra 4-pin CPU cable.  It just has one 24-pin and one 8-pin CPU cable.  

Can I just leave the 4-pin CPU port, which is located at the top left part of the mother board when the CPU is on the top, not connected?  

The manual says that 4-pin port for the VRAM.  What will I miss by not powering the VRAM?

Thanks
