In middle of putting in a new 850x power supply. My current mobo has 8 + 4 connector, but the Corsair doesn't have connectors that split. What to do?

As stated my Rog b550 has one 8 pin input t and another 4.

 

My current evga has the correct connector but the Corsair doesn't come with it.

 

What is the other 4 pin for and is it even needed?

You probably don't need the 4 pin if the 8 pin is plugged in.

 

Although are you sure the connectors don't split?  I have an RM850x on a Asus X570-F which is the same layout and had no problems doing so other than it being a tight fit because they do not come apart very far.

I'm an idiot. They do split, they were just stealthy. Thanks!

Indeed I realised this after installing! Derp moment

Since you are here, I have a question that you may be able to help me with.

The reason for changing the evga 750w GA was because during high fps game son a new 3080 it was making coil whine (was the psu)

Installed the new Corsair 850x and at high FPS 120+ there is still some coil whine coming from the PSU. Not as much but it is there. 

I have my PC connected to a Cyberpower Pure sine wave tower  (CP1500EPFCLCD)
 

Any idea what's going on here? The UPS load is topping out with spike around 600w.
 

5600x

3080

The 3080 are very spikey on the power, I think its quite normal for them to cause coil whine.  I think mine does slightly but I can't hear it unless I'm really close.
