How many things can I power on one molex cable?

post #1 of 4
Thread Starter 
I have a seasonic X 750 power supply so I assume its one of the best ones available for this power wattage.

I currently have my h100 pump, my NZXT Mesh fan controller (which is powering 5 fans all on different channels currently but I am planning to run two on 1 channel and 3 on the rest when my Y splitters come) and my NZXT white LED strips.

I just bought two12inch cold cathodes though also. I think my molex cable only has 3 connections so is it safe to daisy chain a inverter for the cold cathodes on to this?

Guess it sounds stupid but I only have one sleeved molex cable but I don't want to overload anything on the cable.. if the pump isn't on my pc would instantly over heat ya know?

You typically don't want to exceed 11 amps through one molex. Add everything up and see what you come to. The risk with exceeding that won't be with the PSU but with the connector itself. You don't want to fry the wires and start a fire. thumb.gif

Each thing's amperage is usually listed under its specs, but you can calculate it with wattage too by just dividing it by the voltage, which is 12 ,assuming everything on the chain will be running at 12v. If not, just adjust accordingly.
