Can I plug a 24 pin extension cable directly into the PSU?

Can I install a 24 pin ATX cable extension directly into the power supply? I have just purchased a Lian Li O11-DXL case and am wondering if this is at all possible? The 24 pin cable that comes with the PSU has another 10 pin plug that goes into the PSU next to where the 24 pin plug goes into. The 24 pin extension cable ( black and white mod cable) only has a 24 pin plug.

 

No. You need to buy actual sleeved replacements for that.

 

Thank you.

 

Make sure to buy the right cables for your specific power supply, the pinouts differ significantly between manufacturers and sometimes even between models of the same brand. Getting the wrong cable that still fits could spell disaster (read: magic smoke goes bye-bye) so it's worth checking

 

Seems strange that the PSU end would have a 24+10 on the PSU end, In most cases its the same number of wires or sometimes less on the PSU end but I have never seen more. I have a corsair PSU that does split 24 pin cable on the PSU end but its 14+10 not 24+10.

 

18+10 is common for Corsair, EVGA and a few others, but the pinouts differ.
24+4 (straight 24-pin with a set of optional sense wires) is relatively common too, usually for Silverstone, not sure about others

 

Mine is the Corsair RM 850..

 

Plugged it all in and switched it on.... no smoke no bang so all good so far!
