What do you guys think:
Stacking 3 boards and powering with a DPS2K? Should have enough juice left for 2 S3 units I think.
Just gotta get coolers and a controller. And whatever stand offs will work.
Anyone have suggestions on standoff a for these boards?
Those PSU Should work fine and run on the sweet spot of >90% efficiency with only 60% load. Slightly less efficient if you added the S3s, but still ~90%.
I'm not sure on the boards hole diameter, large enough and you may get away with cheap threaded rod with lock nuts for standoffs.
failing that you could use short threaded rods with locknuts on each board and then have drilled wooden dowells (broomstick) that go in between boards. Paint them black if you have spare time b4 boards arrive
