So I got a power supply like 3 months ago and it seems like an old power supply because it has a red volt switch. I haven't encountered any problems with it but it doesn't have a on and off switch. I am worried that it might be a low quality psu but I haven't had any problems with it. I don't know the name of the power supply because I haven't really checked. Is it safe? It has held its self for 3 months so is there a chance that it can short circuit in the upcoming future?
