Need some expert advice, 2X 295X2 Quadfire.

Hi guys,

I know that this community is well known for its knowledge in the field of PSU and their functions. I have been reading many of the articles posted here and had use of them.

I currently own a 295X2 and a 290X, and my power supply is a LEPA G1600W.

It works really well, but I'm looking to get another 295X2 to replace the 290X, and my question is, how should I connect the PCI-E cables?

Current setup

The current setup is easy, I got the R9 290X connected with one cable with two 8 pin-connector, it shares 12V rail with an SSD and a HDD.

The 295X2 has 2 different cables from two different rails, one for each 8 pin connector, and the rails are only for the GPU.

But . .

If I get another 295X2, I'm forced to split it up somehow. My processor is an overclocked 5820K, the MB and CPU has 12V1 and 12V2, therefore I exclude them below.

12V3 is standalone.
12V4 is shared with devices.
12V5 is standalone.
12V6 is shared with devices.

Each of the above have 30A on each, the 12V1 and 2 is 20A.

I'm posting some pictures below.





What setup with the PCI-E cables would be wisest?
Give each 295X2 a seperate rail and one shared?

Please let me know what you think, or what you would do.

Thank you.
