Question Need to connect another 6-pin sata power cable to an 8-pin connector?

[EvanVanVan]

Ideally, I need to connect one more sata power cable to my Corsair RM750x but I'm out of 6-pin sata power ports. I ordered this (https://www.amazon.com/gp/product/B01DV1Z32Y/) 6-pin to 8 adapter cable hoping it would work. Unfortuantely, I didn't realize doesn't fit because two of the 8-pins are connected and the one squares needs to be domed.

I can jam the 6-pin power connector into one side of the 8-pin port, but because the clip is centered on both the clip doesn't really line up/fit nicely.

Is there another cable or adapter that could work? Should I just use the 6-pin connector in the 8-port?

Thanks

That is a PCI-E cable not SATA.

Ok, is there another cable available or can I just force the 6-pin cable into the 8-pin port? (Really the only thing that requires forcing is the clip)

You don't force anything.

Sata and molex also provides 3,3v and 5v where PCI-e does not. So if you need those voltages it's not possible to convert PCI-e to sata and molex.

What's hooked to sata and molex atm and where do you need more sata/molex for?

Ok, thank you. That does make the most sense. Hopefully, I'll be able to the three to four 3.5" drives and an SSD off the one PSU port without issues?

It's a truenas server with (16) 3.5" drives and a (17th) boot drive (SSD).

Be aware that the PSU only provides 20A @5v. Depends on the brand and model of the HDD but usually I count with 1A @5v for each HDD. That means you can connect a max of 20 HDDs to your PSU.

Ty, but I have this awesome case that supports this many hard drives natively https://www.fractal-design.com/products/cases/define/define-7-xl/Black TG Dark Tint/

Nice, Ty

I get that you have the case for this.
But you seem to be lacking the connections for all these drives.

Was just a suggestion.

Yes there is.
Sata Power Y type cable.

If you have molex plugs available, then also molex to sata power adapter.

Just to make it clear and emphasized for future reference, *never* try to power a component from part of the power supply that goes to a different component. If you had successfully jammed the cable in there, you might no longer be the owner of whatever was to be connected to the other end.

And adapters are *never PSU side. Adapters are for the universal parts on the components themselves, not the proprietary ports of a modular power supply.

Nice, Ty

Other thing: sata and molex cables are wired with 20awg that can provide 5A each cable. That means you can hook a max of 5 HDDs to each cable that comes from the PSU.
