Powering the Backplane Directly

Hi all. Sorry if this has already been answered but I have one (hopefully) simple question. Can I power the backplane directly using the PSU’s cables without using the breakout board that collects 6-pin power and breaks out to 4-pin Molex and fan power?

I am already powering the fans directly from the board’s fan headers and if I can bypass this board and run (4) individual 6-pin to 4-pin Molex cables from the PSU using the manufacturer’s cables I will. It makes for a cleaner run.

The root of my question is really whether the backplane Molex are standard Molex power pinouts or not.

Thank you!

I think the answer to that as asked is yes. The issue/concerns will be around physical form factor–you need the connectors to be low profile if you still plan to use the 45Drives case, and around spreading out the power delivery; you don’t want to connect all four backplane molex to a single SATA/PATA port of the PSU via some sort of cable with four molex on it; you want to aim for one PSU output driving at most two molex connectors.

Thank you! I do have low profile Molex because (un/fortunately) I am using SATA to Molex adapters. That pic was really just for illustration without confusing the matter. I will be running 4 individual 6-pin to Molex power, just as the original did, however using my own cables instead and plugging them directly into the backplane. I will report back and share more pics. Thanks again!
