Hi there, so i want to try sleeving my power supply cables. I have a modular power supply from Silverstone. I noticed that if i was to try to sleeve my PCI-E Cables, they have these large bulges within their heatshrink. Upon further inspection and testing on an unused cable, it looks like a battery is attached to two of the individual cables. This obviously poses a problem for sleeving the individual cables. My question is do I need this battery-like thing attached for it to work? Or can i remove it to move on with sleeving the rest of my cables. Thank you.
