"im splitting the all 6 hhd power plugs "
You do realize when you split power cables you are dividing the power in the lead by 2 causing each lead to only get 50% power ?
IMO, unless you have a server built to run that many hard drives you have an absurd number of HD's installed to start with !
I just took a look at the hec X-Power Pro 650
I think you are making the classic error of looking at the "650" & thinking you have plrnty of power.
With the way the power is split up you don't have anywhere near the power on the +12V rails you probably think you do .
In order to be putting out the juice that PSU is rated at it has to be pumping 19A X 12V = 228 Watts X 4 rails = 912V .
Considering that anything over 1 rail are "virtual rails" , meaning the power is spilt from 1 output rather then javing 4 actual outputs [that would make a PSU HUGE !] you probably aren't getting anywhere near the USABLE power you expect per "rail" .
I personally think you simply don't have the power to run all those HD's by splitting the connections,
BTW, Out of curiousity, Why 12
hard drives ?
From what I can see that is 6TB of storage !!!
