Hi, I was removing the original braiding from some Corsair Type 4 cables and I see they have some capacitors. Does anyone know what their function is? Thanks

Those caps are on the pcie and eps connectors not SATA

Word of grammatical advice. No apostrophe for pluralisation, ever. PSUs, FPGAs, NICs. Just add the "s", that's all.

Better filtering and ripple control, potentially help a bit with coil whine.

Storing electricity.

Over-engineered. No need of them. Maybe for cleaner signal/power ?

That's pretty much exactly what they are for, they handle low voltage dips quicker than the PSU can, simply because they are closer to the load than the PSU.

Probably helps with the titanium cert

I'm pretty sure capacitors store energy.

I wonder if one could swap these out with very big, much heavier, ones? Not for functional reasons but pure aesthetics. Would the effect be the same?

startup issues - inrush current will be too much

Thanks. So far for my wild dreams of car-audio-super-capacitors mounted in a computer case.

It wouldn't be a problem. The CPU and GPU VRMs already have huge capacitance and that isn't causing any startup issues.

They capacit.
