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.
there many types of risers, so many possibilities as per what config you have or want, and what PSU you are using.
