From the project

Current Sesame Projects

This project is a small PCb on which you plug a standard ATX PSU.

You can use it to power up OCP servers plugging it directly on the servers (Leopard V2, Tioga Pass and Yosemite V1) or using the busbar (Leopard V1, Bryce Canyon, Big Sur).

It is also compatible with OCP Medusa cable to power up 3 servers at the same time.
