Hi everyone. I am trying to move my Supermicro X9DR7-TF+ motherboard from my SC846 case to a new SC847A case to make room for more drives. The MB works just fine in the SC846 case, but when installed in the SC847 case, the it hangs on boot with "system initializing" and post code A3. It's a dual CPU based system.
In trying to track down the issue, I noticed the SC847 which has the 1400W redundant PSU's only has a 20 pin ATX cable that plugs into the MB, not 24 pin. The X9DR7-TF+ motherboard manual explicitly warns that a 24 pin ATX cable and the two 8 Pin PCIE cables MUST be used.
It's a little weird that the SC847 doesn't support the 24pin ATX connector. Should I try and get an adapter or give up on this?
Thanks
mike
