Hey guys.  On a modular psu I have, one cable possesses 2 6+2 pin connectors.  Would using both from one cable make a difference in power delivery compared to using one connector from 2 cables?

 

Id venture to guess the psu is designed so all connectors can be used off one, but what do you think?

The cable itself is electrically capable of delivering much more power than the 150w specified in the 8pin spec. Knowing that, PSU manufacturers sometimes have 2 outputs out of a single cable, because it can handle the load just fine.

No, there'd be no advantage to doing that.

I am not a professional. I am not an expert. I am just a smartass. Don't try and blame me if you break something when acting upon my advice.
