Please show me where I insulted you. Alright, let me get it this way, this is something everyone here should already know about and I don't know why I'm explaining this but, you should never run anything on a junk PSU.
On a technical side, there is no clear info on that unit, only a site and a few pics. From what I see, it has the space for a 120-240v switch on it's back and is a very cheap unit. It likely doesn't have APFC. If it has a flaky +5VSB rail, it may just shoot the board dead out of nowhere. Or if it has high ripple, it can slowly kill his parts. Or if it's protections don't work, it might again, kill everything. And I don't think it has a MOV either. So it might also kill his system at the time of a surge. And so on.
