Techinally in extension cables, because I'm buing affordable extension cables for power supply to use with VS550 and painting them black. I have red that I need special paint, dye, or some lacquer for that. Also I don't care about sleeving and they are more expensive.
So either that or If you know cheap black not individually sleeved extension cables? I buy from Ali regularly.
