Title: How to Connect S5 to Corsair CX750M
Post by: edric on September 25, 2015, 10:06:37 PM
Hey,

I was wondering if someone could help explain how to connect my S5 to this Corsair CX750M. 

http://oi57.tinypic.com/5z49w5.jpg

It came with two of these cables (dual 6+2 pin PCI connectors)

Do I plug them into these two ports?

If so, how do I know where to plug them in on my S5?  Thanks!

several things:
1. Don't forget to "jump" the PSU. use paper clip (cut it or use a larger one) to get a U-shaped structure, then connect fourth and fifth connector (fourth is green, fifth is black) in 24 pin connector (on the clip side) with this paper clip. The best is to insert the 'legs' of the paper clip inside the connector without damaging it-should be OK, but proceed cautiously. Some people tape it afterwards or use isolated wire instead of a paperclip, because obviously you don't want to short it by accident.
2. Insert the connector that has 8 pins (Not 6+2) into the receptacle on corsair that says 6+2 PCIe. It has to go only in one orientation (it will be obvious).
3. attach two branches of a branched cable to the 6 pin connectors (look whitish on your photo) on the same side. CX750 has two branched cables, so I cable per board, each branch engaging a connector.

BTW, i still have two CX750 and two CX500 if anybody wants them.

Thanks for the tip on jumping it.  Last one I got was already done. 

So I need to insert two of those 6+2pin PCI cables and connect them to the same side of the miner long ways like in this picture?

this picture is not very clear.
i am not sure what is that yellow stuff. corsair cables are black, so it is probably a different psu.

Yes plug all 4 connectors, don't mix power supplies on the same board but you,re only using one so no problem. Once running for a while make sure the connectors aren't burning hot. If they are you will have to unplug the +6 and use 4 individual cable.

Thats it.

Always check the temperature of cables and the coupling at the psu and miner!!!

The main cable will have ~280w passing thru it! if quality of the cable, or the pins, or the pins enclosure is bad, than you will have problems!

If they get too hot, then i would think of getting 12v from molex and 8pin cpu! check the pics beneath

Thanks everyone.  I got it all working fine.  Found some youtube videos to make sure the cable were connected right.  As far as the cables being hot.  I just checked.  They are warm, but not hot.  I spread the miner from the PSU because I thought the warmth could just be coming from the miner.  The hashing rate is good so I think it's all good.  Thanks again!

Good luck with that S5. The best solution for the heat and noise i found was to use a big box fan and have air block through the fins by putting the miner sideway. This would also cool the wires so 2 bird one stone.
