And here are the pics of what you will receive when ordering the Bladecenter H breakout board, and how to assemble it to your PSU.
Pics are clickable for higher resolution.

Back of the board
First step, you will need to remove 3 screws from the PSU and replace them with the M3 spacers.
2 short spacers are used at the bottom
1 long (white nylon on this picture) spacer goes to the upper hole.
Second step, put the clip-on spacers in the holes on the back of the PCB.
Turning them while pressing could help.
Next step, put the breakout board in place on the PSU, and gently press it until the clip-on spacers are touching the hex holes.
Press firmly the clip-on spacers so the enter the hex holes at the top left and top right side of the PSU.
Last step, fasten the 3 screws in the hex spacers, and you are done. Everything is secured and shouldn't move when plugging or unplugging the PCI-E cables.
Connect your power cord, the PCI-E cables and enjoy the high power.
The board needs 1 IEC C19 power cord, and PCI-e cables with one 6 pins plug at both ends.
The PCI-e sockets are rated 9A on each pin, meaning you can draw up to 27A on each socket.
Only use high quality cables if you go that high. 16 AWG strongly recommended.
