An EXTREMELY loud BANG (heard even two floors down!) was emitted from the PSU accompanied by a bright flash. Yes, the XFX Black Edition had failed in a potentially dangerous way. Luckily none of the OC3D equipment was damaged by the elaborate death of the XFX PSU, but it is extremely worrying that the OCP protection on the PSU didn't kick in for a second time. Of course this could be put down to the unit being from a faulty batch, but as the unit tested in the video was the 2nd one to suffer this exact fate at the hands of our MAX LOAD tests, something does indeed seem wrong.
