3x 7970's 1250X Seasonic PSU (PCI Plug problem)

[zerk89]

Okay so there is the picture of the PSU i am going to get. I am planning on hooking up 3x Gigabyte 7970's to it, It's not so much a question of power supply because i know it's way more than enough to handle them, but i'm confused as to how it's going to take all of the pci-e auxilary power plugs.

Eg. Each card has 1x 6-pin, and 1x 8-pin slot (6+2)
For a total of 3x 6pins and 3x 8 pins (6+2)
Do you think you would be able to plug them across the little gaps you can see in the PCI-E Section in the pic? They are in 12 pin sections as you can see.

If i plug one 8 pin into one 12 pin section, then there is only 4 left in that section and the other 6 pin plug for the same card would have to plug across that mini gap between each 12 pin sections...

How the hell are all the pci-e power plugs going to fit?

Any help appreciated

PCI-E cables for x-series comes with one cable but split into 2 (6+2) pin. You don't plug them individually. I have one and they are powering my 3X 7950.

Cool thanks for the reply, yea i only just found out about 10 minutes ago, searching for pics of the cables, since my PSU is in the mail, i just assumed the plugs would match directly on the back of the PSU, but yeah 12 pin module = 2x (6+2 pins) on them, which is pretty cool, they turn 12 pins into 16, i'm guessing they merge the grounds into one or something, either way im glad, thought i was going to have to return it.

if you havent purchased it yet, you could always buy the xfx version which is a lot cheaper. saving you cash!

(its the same seasonic components inside)

heres a clue..

It's already in the mail, plus i just checked and the shop doesn't stock the XFX.
I will be running the rig 24/7 just mining litecoin.
Doesn't save you a penny to be cheap is what i was always taught.
If it was just for my gaming PC i would definetly switch it out either way.
