Can I plug 6-pin SATA power male into 8-pin female on PSU?

[Youser]

Hello, all!

I own a Toughpower TPD-0750M PSU, which continues to work great.  Nice job, Thermaltake!

But now I need to provide additional power connectors for 6 or maybe as many as 8 more new SATA HDDs (I have plenty of available SATA data connectors). But while I have several unused 8-pin female connectors on the PSU itself, all of the 6-port SATA power connectors on the PSU are already in use.  Now, I know that I could use one of those 6-pin power ports by attaching a series of extra SATA power connectors for all the new drives, but my gut says using a single 6-port PSU slot to power perhaps eight 3.5" SATA HDDs isn't particularly wise (but I'm not an electrical engineer, so what the heck do I know?)

What I'm here to ask is whether I could safely insert an additional 6-pin male SATA power connector to one of the available 8-pin female connectors on the PSU?  And if so, which side of the 8-port connector should I insert it into? The left six as you face the PSU connectors, or the right six?

Even if I had the 8-port connector's wiring diagram, I'm realize that I'm not capable of determining the answer to this question.  That's why I'm turning to you folks.

What do you think?  Thanks!

Hi, 

the pin define of 6-pin male SATA and 8-pin female connector are different

so here I will suggest you if you have available peripheral (4-pin female connector) on power supply, 

you can buy the connector which comes into connecting with SATA and peripheral

hope it can help you out
