Hey guys, i just hooked up RGB to my case and i connected the fans to the same sata cable as my ssd which boots windows, would this cause any issues? Like instanability?
According to the SATA specification each pin of the SATA power connector must be rated for a minimum of 1.5 amps. Three pins in parallel are used to carry the +5v current, so the “simple” answer is 4.5 amps.
However, there are only five ground pins, shared between the +3.3v, +5v and +12V supplies. This allows a total return current of 7.5 amps, shared between all three supplies. If the sum of the +3.3v and +12V currents is greater than 3 amps, than the allowable +5V current is reduced accordingly. Obviously, if you are using only +5v, then this restriction does not apply.
Caution is advised! Whenever multiple pins are used to carry a high current, one pin may not make...

Caution is advised! Whenever multiple pins are used to carry a high current, one pin may not make good connection and cause the other pins to carry more current than they are rated for. Power is still supplied, so there is no clear indication that anything is wrong. But, this will eventually cause overheating and connector failure.
