I've built dozens of PCs in the last two decades and I've never had a power supply unit like this. It doesn't seem like such a big deal, but it's actually so annoying that you can't use the PC. How the hell do I get this thing back under warranty? To get back to business, I turned off the eco switch (which stopped the fan and beeping). It doesn't generate much heat so I'll take a look at the core temp and see if I need a new PSU or not, but I definitely won't be buying from these guys again.
