Okay guys, I'm deciding if I should remove the capacitor or not for the custom sleeving. The Silverstone ST-75p (750 Watt) power supply has these 2200uf capacitors on the cables. I found out what they are used for:
To reduce electrical whine/buzz associated with high performance graphics card’s dynamic loading changes, 2200uF capacitors are attached to PCI-E connectors. This design also helps to maintain better voltage stability and improve ripple & noise performance.
It looks like it doesn't alter the voltage so removing the capacitor to sleeve the wires should still provide the necessary voltage to the video card (XFX 5870). I'm looking for help in deciding if I should go without the capacitor for the individual sleeving. Any thoughts?
