Looking for some input. My issue is with my power supply and I hope I have posted in the appropriate thread.
Is there any know incompatibility issues with Seasonic X series PSU's and Supermicro motherboards?
Back ground to my inquiry:
I am an unRaid newbee and have had my server together for about four weeks now. I researched for several weeks prior to parts purchase, assembly and use of unraid and decided it best for my needs and thought i used all proven known good hardware. I followed the 20 drive beast tower build as a guide. I changed the psu thinking it was an upgrade in reliability and performance. I went with a SeaSonic X750 Gold 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply from the egg. My board is the SUPERMICRO MBD-X8SIL-F-O with 8GB of Kingston Server Memory Model KVR1333D3E9SK2/8G. I currently have 3 Norco cages with a total of 14 drives mixed green and 7200 rpm [1 x parity, 1 x cache, 12 x data] for a total of 15TB storage.
1st boot - got the 1 second blast of power enough to move the fans then nothing. Went thru all connections tried again an she started right up.
Over the course of the three weeks I built up my sever copying data, preclearing and adding discs to array repeat until I got to where I am now. After no longer adding drives and wires realized the power up problem was not going away. If i powered down and later tried to restart i would get the one second burst and nothing. I would have to flip to PSU power button off [MB lights no longer on] four or five times to get it to boot so I contacted customer support at seasonic and they immediately processed an RMA and shipped me a replacement. Well I received it yesterday and promptly hooked it up. Now I have quite the opposite problem, it wont shut down. Using the powerdown button on the web gui it goes through the motions and proper shutdown sequence and the sever powers off - for 3 seconds - and then automatically reboots. Very frustrating. Repeated three attempts with no change, removed UPS as source power, no change and plugged directly into wall socket same thing. Contacted support again this morning and received this response:
Dear customer,
Thanks for your prompt response.
It seems like there is an compatibility issue between the motherboard and psu.
However, we'll send you another psu for testing.
I replied asking if it was possible to send along new wiring harnesses to eliminate the potential of one being bad and received this response:
Dear customer,
Thanks for your prompt response.
I also re-checked your RMA request form, I saw super micro MBD-X8SIL-F-O.
Their motherboards are known for most of psu not compatible recently, because they carry their own brand psu.
I promptly replied that I have tried 2 known working psu's and have no trouble along with some other comments.
Currently awaiting a response.
I thought Seasonic was the best...Did I choose an incompatible PSU?
If you've read this far thank you. I needed to vent. Any comments, criticisms, or sympathy's accepted.
