Mount two Mean Well LRS-350-12 PSUs, with a small offset to leave terminals accessible. M4 holes in top to allow for attaching accessories, such as a Baldrick8. Pattern is 122mm x 85mm.
May work with other power supplies, such as the Mean Well RSP-320-5, cross-check the mounting hole spacing to verify
Photo was before I added 10mm of extra space for airflow between.
