So your saying rip them out and throw them at Jesus?

Or leave them on

leave them on... they re doing you a favor

*if your inputs are bouncing in voltage.. it can make mobo/GPU squeal even more..as the squeal is often caused by the inductors [ferrite chokes] on the mobo or GPU dealing with crappy input voltages. The ferrite chokes on the PSU cables, help to eliminate some of this fluctuation before it gets to your rig..

Oh..and the Antec TPQ has chokes and capacitors in-line... chokes for keep power supply smooth and without fluctuation... capacitors to filter noise and help with voltage supply.

Right so it doesnt matter how short the cable is ect, just put them on somewhere near where they are now on that run of cable and it will do the same job as it is now

If there magnets could you add some regular type ones to the end of the cable and heatshrink them would it do same purpose?

I believe you could for the same effect... the ferrite cores used though, are very strong magnets.. not sure where you would get a 'household' magnet that is both that strong and small... unless its like neodyium or something..

Ferrite choke is a choke (inductor), not a magnet. The key difference with a normal inductor is that it dissipates the excess high frequency stuff as heat rather than just storing the energy and releasing it.

As an inductor, it opposes changes in current. Higher frequencies are attenuated more than lower frequencies and especially DC.

OK I see thanks for clearing that up guys. I learn something new everyday!

It's a ferrite ring. It reduces EMI emitted from the cables, and EMI picked up by them.
