They cut it beacuse the original cord is not a C14, it's the same head as the other side that plugs into the PSU. Only usable if you pick up the specific PDU. I've had to cut all of mine off too.
Perhaps the WiWynns come with a C14 but the Quantas, so far..are all the 3 pin molex-ish plug.
Here is a photo of four racks of these OCP servers that we just installed. Idle power per rack is around 28A 208V (4.6A on each leg of two 30A 208V 3-phase feeds) which really isn't bad for 104 Xeon E5 V1 CPUs, two switches, and a router.
BTW: The servers in the distant background belong to Sony and have something to do with the PlayStation. There must be two dozen racks at least- brand unknown.
Many thanks to Syndroma for providing me with a copy of the "Facebook" firmware for testing.

The power consumption on B10 seems to be about 10% lower than A07, though this could just be a difference in configuration since the flashing wiped my settings. I did try to configure the same settings in B10 as A07, but since there was a slight difference in the options available in the setup menus, I cannot guarantee they were configured identically.
Dual E5-2630L with 8 DIMMs and a Quadro NVS 510:
A07: 50W idle
B10: 45W idle
B10 also looks a lot cleaner in the AMI setup, as there aren't half-completed menus strewn around. Also it doesn't spew "Running on Hardware" messages over the serial console like A07 does.
B10 also has an option in setup for PCIe hot-plug support, something I did not see in A07.
Also perhaps of interest to voxadam, B10 includes an option to enable the SAS option ROM. Although since I don't have the SAS headers soldered I can't state whether the ports actually work or not.
The miniSAS PCIe links still do not appear to work (at least when connected to each other).
Unfortunately my holy grail of S3 support is still not working. I think I might try installing Windows and see if suspend works in Windows, because it isn't working at all for me in Linux.

A quick summary of the differences that I can spot, B10 has these additional devices which A07 lacks:
Anyone have experience resetting the BIOS, or pulling the chip and flashing with a USB programmer? I was updating one of my Quanta boards to FO3C3A07, and it never came back to life after rebooting. I'm assuming the flash went bad somehow, since it was working fine before and swapping out the components didn't help (memory, cpu, etc).
The quanta bios readme says there is a BIOS jumper somewhere:

I do not know if you mean you have update the BIOS correctly, but it just cannot boot (no video output) after the reboot.
If you do mean this, I will suggest you leave it turn on for 24 hours. It may comes back after some time.
It happend to us that we updated the BIOS correcly, but there is no video output afterward after the reboot. We accidentally found out that if this happened and leave it power on, it can comes back after some times passed.
This sounds stupid, but it happened to us MANY TIMES.

Original PSU died in a month. Thanks to this STH thread it's now powered with an old 650W Supermicro PSU - 12V 50A is all this system need. Still a nice, efficient and silent server.
I have a bunch of 750w gold HP common slot's laying around, I plan to order a breakout board that is uses screw down connectors for the terminals.
Based on page 22 - is it really as simply as running 4 14awg wires with spades, and clamping them to the P1/P2 P3/P4 prongs on each mother board?
Would I wire this to the intermediate backplate that provides power, or would I remove that backplate that the nodes plug into and run 4 wires to each individual node board.
4 14awg wires seems a bit small for up to 750watts, If I would run the HP PSU to the connection where the PSU connected previously. Seems almost safer to run 8 wires total, powering each node individually.
15 amps is the maximum for 14 awg @ 12vdc - so roughly 180watts. You would need to run 4 wires on both negative/positive here.
Simple female 14awg terminals might be too loose of a fit for the amount of amps running through. Anyone have any recommendations for terminals to clamp onto these?
I don't know why it seems difficult to make a BIOS dump available, but it's weird. Maybe there is a Facebook MiB team, after all
Anyway, i'm looking for a dump of the F03C3B10 BIOS (or F03C3B11, it was shown here at least two times), because there is some strange behaviors with my fully updated Connectx-3 mezzanine card (probably with SR-IOV, but not sure), and i want to try the bios before looking for another OCP card.
Thanks you
Other question, is there some 3D models of the Windmill node "front" ? I have 4 nodes, and i have to move them every month for events. There is no flightcased rack option easy to pull, and even, it's pretty fragile with all the stress of the cables directly applied to the motherboard.. So i'm looking for a custom made metal cover (or 3D printed, for testing). I will make that, but having a 3D model to begin on is a big time saver. Of course, it will be posted here if the project is viable.

Yes. Use something like the ch341 programmer with a SOIC16 socket. Very easy since the SOIC is socketed on the Quanta board.
Before you spend a day waiting to see if the node behaves, consider putting a UART to USB adapter (anything Adruino compatible will work) on the debug header (pinout is mentioned in the OCN PDF) and see if there is any output to the serial console.
Default parameters are either 57600 or 115200, depending on your BIOS version and previous configuration. 57600n8 should be the default speed.
Between BIOS versions there's been some variation in whether VGA is initialized or not. Serial console always works though, so I would check that first.

I don't have the backplane so I cannot comment on how you would power that.
If you want to power the motherboard directly you will also need to apply 5V to pin B4 (PSU_PG) or it will not start.
So for the bare motherboard you only need 3 connections:
12V to spade
GND to spade
5V to pin B4
You can find the pinout of the mating connector in the OCN specification PDF. Pin D1 is the short pin, to orient you.
FYI the PWM output from the motherboard is inverted. So if you plan to use a PWM fan and want it controlled by the motherboard (which you probably don't, because the fan profile is brain dead) you'll need an inverted PWM fan or a CMOS inverter between the board and the fan.

Well... that is a bit overkill lol. I'd be happy with hard wiring a few winterfells for V2 cpu support. I have Wiwynn but being stuck on V1 sucks. Given that V1 cpus are getting so expensive now, may as well get E5-2680v2.
