PROBLEM: Setting up the first 6 GPUs with risers, I used all the molex cables and was left with only some 6 PIN to 4xSATA cables. So, when it came to powering the two 4 PIN AUXPWR ports on the Mobo, all I could use was a single 6 PIN to 4xSATA cable then use SATA to molex adapters to plug into each of the two AUXPWR ports.
On a scale of severity, how bad is that?
Those adapters always feel cool though.
Using Sata cables with the sata-molex adapters to power the motherboard is perfectly safe, the motherboard doesent use any power from them if you are using powered GPU risers, which in your case you are. You dont need to have those AUXPWR ports plugged in at all.
If I can find a website/service to make some more molex cables for me that work with this particular PSU, is it still possible to use one single cable to power both AUXPWR ports?
Last question, there is allot of warnings about Molex to SATA adapters and to not use them with risers. Does that go for SATA to Molex as well, or all adapters that are sold ? i have a splitter; 8 PIN female that splits to 2x6+2. Are these a risk as well?
Sata to molex adapters should be avoided for powering risers (can be used with nvidia cards, not with amd). If you only have sata cables, and need to power risers, then buy the sata power type risers.
As for the 8pin-2x6 splitters, those are pretty safe always.
Thank you so much for this. I will lose both those SATA to Molex adapters and either buy some of those 8s risers which have SATA, Molex and 6 Pin connectors. Then decide to either go with the SATA connection or use the Splitter and the 6 PIN connection.
Many thanks again.
