People have linked the connector required and also shown how to direct wire an ATX psu. I know it is 22 pages but there is a lot of great info in those pages.hi, could anyone can provide some photos of the power connectors on the motherboard, the psu and the cable? would like to get a solution for standard atx psu
Yes, if there are any safety concerns raised by the provider or quirks regarding power/connectivity/maintenance/administration.Im running mine on 208v at home. is there a specific reason at a datacenter matters?
Thanks, I'll go back and look into those posts.
What about Imgur, Google Drive, Dropbox or whatnot?I got some pictures for you but no way to upload on the forum, either they are too big, or as my latest post has been deleted my account is in a mess. if you can ping me through private mail I can send them to you, or explain me how to upload a 2.4 MB picture inside the forum no issue. There are the place for the header, and we will be testing to add them. The key issue is BIOS support after.
I'm curious about these connections as well. According to the OCP docs (§4.5 and §10.2) PCIe port3a/IOU1 and 3port3b/IOU1 of the CPU should be routed to the miniSAS connectors. These PCIe connections are/were designed to allow for multiple systems to be connected together using PCIe NTB (non-transparent bridging).Firstly, is there any chance someone can grab a high res shot of the area that's supposed to have MiniSAS connectors? I know the Quanta boards aren't fitted with them, but I'm curious if it's just the headers that are missing.
So the purpose and usage of the external PCIE links is over my head, but I've been looking into what's not attached on the boards. The specification includes 5x MiniSAS headers - 2x Right angle external (presumably 8088 connectors) and 3x vertical 8087 connectors.I'm curious about these connections as well. According to the OCP docs (§4.5 and §10.2) PCIe port3a/IOU1 and 3port3b/IOU1 of the CPU should be routed to the miniSAS connectors----
---Anyway, even forgetting the possibility of NTB having access to two additional x4 PCIe ports is intriguing.
In the event that not everyone is comfortable with hacking power supplies, or simply would prefer a premade solution I found that there are adapters available for the HP Common Slot power supplies. It seems that the PSUs are quite popular with *Coin miners and someone decided to fill a void and market a fairly turnkey solution.

EDIT: Oops, forgot to mention something.
I also found another adapter that was designed to power up to eight PCIe GPUs which I thougth may be of interest to someone.

Just an update. So I think I was just impatient on the boot process of this. All the BIOS settings worked and VT-d is working just fine (setup a 2012R2 server and dedicated a GPU as well as USB Keyboard and Mouse.
