Walter S Posted March 3 Share Posted March 3 I could use a suggestion/advice, I have two StartechUSA trayless 3X5 HDD modules, each 5 HDD unit is powered by 2 SATA inputs. I have a Seasonic Gold 850W single rail power supply. I also have 2 single StartechUSA units for each of my parity drives, along with 3 SSD's inside my Antec 1200 case. I would like to power the 3X5's modules with two separate cables from the PSU instead of using one line. The problem I'm seeing is I don't have enough SATA outputs on the PSU. I'm wondering about SATA splitters or using the PCIe 8 pin to 6 pin adapters I have listed below, and run SATA power from them to the module or to a single HDD as required. Any thoughts would be appreciated.. https://www.amazon.com/dp/B01DV1Z32Y?starsLeft=1&ref_=cm_sw_r_cso_em_apin_dp_SK62JH351KREWD0Y9ZYA Amazon.com_ Cable Matters 2-Pack 6 Pin to 8 Pin PCIe Adapter Power Cable - 4 Inches _ Electronics.html Quote Link to comment

You are likely to get better results with molex->SATA connectors as the SATA splitters can not reliably split more than 2 way whereas you can normally get 4-way with Molex ones as the molex connector can carry more current without voltage sag.

Michael_P Posted March 3 Share Posted March 3 You can add either molex or SATA using punchdown/pass through connectors to the existing lines. Much better than trying to add too many drives to a single connector using a splitter. You can buy them for like a dollar on ebay. Quote Link to comment
Walter S Posted March 3 Author Share Posted March 3 I forgot to mention, my PSU is modular and all the 6 pin SATS power outputs are all taken. That's why I came across those 8 pin to 6 pin adapters. I do have open PCIe 8 pin outputs and wondered if that might be an option. I'm just concerned the pin assignment (on the PCIe) might not be what I need. I don't want to short anything out. the punch-down idea might be an option thanks Michael_P. I just don't want to put too many HDD on one line. Quote Link to comment
