Does plugging multiple periphals into the same PSU cable affect their performance?

RDKells · Jul 5, 2016

My PSU came with a molex cable that has 4 molex connectors on it.

I am wondering whether multiple devices connected to the same cable will cause the periphals' performance to dimish?

For example, I have 3 fans connected to it currently - so they will they be slower than if one fan was connected? I am going to be connecting 2 SSDs to the same cable soon too so will this cause a further effect on performance?

No, they will work the same- just like plugging in additional devices into sockets at home does not make your fridge or microwave work worse.

Multiple extensions add multiple points of failure (and looks rough) - personally I wouldn't do it, but on low-draw devices, there's no technical (though I maintain there are mechanical reasons) reason why not.

in theory it should not affect performance. That said, I would use one cable for your fans, and another cable for your SSD's. this shouldnt be a problem since I dont even think they make a cable that has both molex and sata connections

Why would you be connecting ssd's to a molex cable? Are you using a SATA adapter? I would not do that if you have dedicated sata power cables. To answer your question not it should not, fans do not require a lot of power there is far more than enough available power through those molex connectors for a few fans and an ssd. But like I said im not sure why you would power an ssd with a molex cable or even a fan for that matter they will run at full speed all the time when powered with molex.
