I have been mining for a while now, and I can't seem to find the culprit here. I have purchased over 100 of these things here over the years. From time to time, they would blow. Most of the time I think it is caused by insects flying into the Adapter Boards and causing a short that makes the PSU pop. I just wanted to know if anyone exprienced might know something that I don't know. I have rigs that ran on one year without any issues, but there are ones that just have a lot of problems. The rigs are setup in a garage and I think the heat attracts the bugs.
I am running 240V going into PDU units which then plugs into the PSU. I was running 6 GPU setups, but figured out 4 GPU is just more reliable and less heat density. I am able to run 4 GPU under one of the HP 1200w PSU. So yesterday I was replacing a blown PSU, so as soon as I replaced it, I boot it up and it popped again within 3-5 minutes. I was like... WTF, OK so I put another one in and it popped. $80 down the drain and I stopped. Couldn't find anything wrong with the system but then again afraid of being an idiot and keep destroying PSUs.
So I am just curious, does the Adapter Breakout Boards ever go bad that can cause this? Or can a bad USB riser cause this? I haven't had a GPU gone bad before. Also I have no Motherboard or CPU.
I have some HP PSU that are still running from day 1 for over 1.5 years. Just can't identify the point of failure. I have seen little flying moth type of bugs fried near my rigs and seen them cause arcing before. Wondering if it could be something else.
