I'm blowing up power supplies like mad.
Working with a SuperMicro X9DRD-iF motherboard and a Thermaltake 240-pin 1275w power supply. I'm mostly playing here...not mission critical.
So, I put the board into a case, connected the power supply and some drives and booted and it was great. I put an OS on the thing and was golden.
The next day, I asked another tech to add an additional icy dock and some more SSD drives and he did.
I booted it up the third day and immediately the UPS faulted. Thinking the initial boot was too much for the 1500W UPS, I reset it and booted again and the UPS faulted again.
On the third attempt, I popped the power supply and it's dead. Two more power supplies and they are dead too.
I'm thinking the board is grounded or something, as this machine worked fine two days ago.
So, now, I have a new PS AND a new MB, but I need to find out why it's faulting.
Any ideas on what's up?
I stripped it down to just the MB and five plugs. The 24 pin, the two 8 pin connectors from the PS to the MB and the power and reset switches are connected. Of course, two processors and RAM (probably blown too) but still no joy.
What can I check to see what's blowing the power supply? Is the BM grounded? What can I check?
