I added 2 fans through molex connections (0.18 Amps each) and now the side panel case RGB does not automatically go on anymore when I start up my PC, even after disconnecting the new fans.
The RGB is connected to the front panel and gets power from a molex, it's not connected to the motherboard (it's part of the PC case).
The weird part is that it does light up when I press the dedicated LED button on the front panel (used for cycling through the colors) but it's not "remembering" to stay on after shutting down and booting the PC again.
What is the cause here and why doesn't it still work after disconnecting the fans?

My final verdict - poorly designed and/or cheaply manufactured electronics within the RGB LED circuit are failing and/or not functioning as intended. OR you (and evidently some others) are mistaken as to the functioning of this RGB LED system. Either way, beyond repairing/modifying/replacing that circuitry yourself (a tall order without specific tools/knowledge), or buying a whole new RGB LED system that is advertised to function as you desire, I think you are stuck with what you've got.
Your (and everybody elses) PSU is fine and functioning as intended - delivering volts/amps. And your motherboard also has nothing to do with it.
The RGB LED system/circuitry itself is entirely the problem!
