Re: Fourth alt coin thread last three got oversized.

can you guys recommend which type of risers I should use? Getting mixed opinions everywhere. I was gonna go with sata risers directly to 6 pins but heard it is dangerous. What is the safest way to power risers?

I personally prefer PCIE 6pin type (riser version 6?) so that I can reuse my 6pin PCIE cables especially when using server PSU.

I have many SATA powered risers in production now and all ok so far.

I guess its a matter of good quality build instead of "dangerous", and if your SATA cable connects via molex onto the riser -- ensure that its tight and secured. I suspect that the real danger is when low quality molex doesn't get in proper contact or loosely contact with the 4 pins -- thats where trouble starts... ie. sparks, fire hazard, damaged riser eventually over time.

For risers I usually take good look on the quality of the USB3 cable... the ones that are "fat" or shielded likely have 100% uptime compared to the flimsy ... phone charger looking type USB cables...

so with PCIE 6 pin risers, you go 6 pin to 6 pin cable directly without using any adaptor?

its like a Y cable (one for GPU and one for riser) .... one single cable that goes back to server PSU

look closely here.... one cable splits into 2 pci connector, an 8pin for GPU and 6pin for riser... this way power goes to both devices at the same time so consistency perhaps makes a stable rig....

Is the cable something like this? http://i.ebayimg.com/images/g/3gkAAOSwiQ9ZPZn6/s-l1600.jpg

6 pin female goes to PSU then 6+2pin male to your GPU and 6 pin male to riser. is it okay to leave 2 pin unconnected and just connect 6 pin tho?

if you are using ATX PSU, you need 8 pins but if server psu the breakout boards are usually 6pin

leaving the 2 pin out is fine -- quite flexible these 6+2 connectors

I never thought of connecting it this way. Most people's setup has separate cables powering risers and GPUs. This is not a bad idea as you explained the reason. so 8 pins to two 6+2pins cable would work same way? Thank you for the enlightment.
