I received two out of the four X-1's I ordered and the first one i plugged in sent a shower of sparks everywhere, so far the 2nd unit hashes anywhere from 9 to 90 Ghz regardless of what the Freq is set to, the errors do seem to drop a bit if it's set to 1000 or below.. Your mileage may vary 
So that's the second power supply we know to have gone bang. How many more, I wonder?Funny how the image showing the PSU manufacturer label seems to have "disappeared". Fortunately Firefox's search history comes up trumps, I originally tried finding a "Sunshine AP187" back when the picture was posted. Here's what AliBaba has to say about it.

Perhaps that's Black Arrow's "surprise"...
Make that two for two on the PSU's, i moved my working unit to the shelf i was going to keep it on, plugged it in and fireworks.. unbelievably craptastic parts BA
That's three so far, out of however many on here have received them so far which is a pretty shit failure rate. Should've called them Prospero X360.Perhaps it's time to give AplusPower the WebOfTrust score they deserve as well.
