Morning Miners,
The internet and the forum seem to have a split opinion and I don't think anyone knows who to trust.
Six Card Set up with Dual-PSUs, should all your risers be connected to the same PSU as the motherboard OR is it fine to split them up and why?
If the answer is YES, how should someone go about connecting 6 risers to a single PSU?
If the answer is NO, how should someone go about splitting them up?
At this rate I'm not honestly sure if we'll get a single answer for this one. Opinion seems so split.

I use this splitter to power the card and riser from one PCIe power cable:

And this riser (note 6-pin PCIe connector):

this is no valid test-period - let's see in a couple of months, i hope you'll be fine
Anyway I'm running 6x1070s off two PSUs with all the risers connected to the same PSU without issue. 8 days no crash.
Risers draw nearly no power. For safety sake consider each one is 5 watts. Consider a gpu will be 150. If you have 2 750w psu's you can't connect more than 4 gpu's as that yields 600 watts. You could then connect all risers as that would put you at 630, right where you want to be for one 750 psu. The rest of the computer can run off the other one.
I struggled to find PSUs at all so I'm running 2x 850w plat numbers pulling around 900 from the rig, wasting capacity I know but I'll swap them out in the future I reckon.
@myriatech so what you're saying is so longer your using an appropriate amount of power per PSU it really doesn't matter at all?
