Beep codes from PSU?!

[Jalmio]

So, I replaced my old time bomb-quality brick with EVGA Supernova G3 750W. Everything seems to work fine but at every power on, including wake from sleep I get this series of beeps. 7 short beeps, then 3 and then 3 again. Always the same 7-3-3 sequence.

 

It doesn't come from the motherboard (I don't even have the mobo beeper installed!), but the from PSU. While this is annoying, I'm a bit worried too.

 

Google didn't offer much. Anyone here know what's this all about?

 

 I recorded the beeps here.

Me neither. Though I doubt it's coil whine; It's the exact same robotic 7-3-3 sequence every time at power on and nowhere else.

Nope, all aftermarket parts. Actually it was a prebuilt in 2009 or so, but everything original is long gone.

MSI R9 390

 

I unplugged everything from the PSU and the beeps have disappeared. Mobo, CPU snd GPU connectors reattached, still no beeps. I yet have to plug sata and molex back in and see what happens.

 

Maybe something was loose.

 

Update: everything's plugged back and the beep returned. I'll keep playing with the connectors.

I haven't felt this stupid for a while. When I first 'unplugged every component to make sure it's just the power supply' I didn't realize to unplug things from the other side of the case.

 

After unplugging everything from the PSU end I realized why. The hard drive I had at some point hung there for aesthetical reason is dead. The beeps are actually the needle bouncing around and then giving up. Now I just had connected power to it.

 

I'm an idiot. Sorry for wasting your time. And thanks.
