Crosshair IX Hero eps question

Hey guys, my current Crosshair VIII Hero has 1x8 pin eps and 1x4pin eps. Both are connected.

 

I am considering upgrading to the Crosshair IX Hero and getting a 7900x3d when it drops but saw that the board requires 2x8 pin eps connectors and I *might* have another 8 pin cable in my psu box but I'm unsure.

 

So question is, would I be able to run this setup and have it post and work with just 1x 8 pin eps?

 

Thanks in advance for any replies.

 

EDIT: I actually may have two 8 pin that can be split to a four pin and thats whsts hooked up, with a 4 pin extra. My radiator and fans cover the eps connectors up.

 

Look at the right side, there's two flat mounted eps cables that look like they have the same amount of wires and possibly pins.

very few consumers board with >1 EPS connector need both. the VIII Hero isn't one of them, it'd work fine with just one 

 

if your PSU is multi-rail and the EPS connectors are on separate rails then maybe it'd help with balancing but beyond that (or sub-ambient CPU OCing >400W) there's no need.

I think like I said I actually do have 2x 8 pin eps but they can be split and used for a 4 pin. I think.

 

Thanks though, good to know if i don't the system will still work.

 

Now I just gotta pray I can even get my hands on a 7900x3d, I expect them to sell out fast.

I don't remember what board I had think X299 tomahawk, the stupid thing came with a dual 8 pin splitter so you only needed 1 8 pin power.  It's like uhhhh doesn't this defeat the whole purpose of balancing loads across PSU ports?  Didn't make any sense to me.
