PSU makes hummin sound, when inverter is turn on
hello. in my car i use, a modified sine wave to power my pc. the problem is, as soon as i turn on the inverter (no matter if the PSU is on , or off ) the psu makes a strange whining noise...
not to mention that, when the pc works, it has allot of noise in sound.
(To solve that, i have cut the ground wires from the psu to inverter)
Any idea what could be causing this? cause i want to leave the inverter Always on, to remotely start the pc, but this sound makes me fear something is going on. would a pure sine wave solve it? or maybe a new PSU?
