In the quest for cheap power & better density, you'd think they would run direct DC to everything, instead of a bunch of ATX power supplies

- graycrow 9y agoThick copper wires for DC probably cost more than energy converted to heat on that power supplies.
- ty_a 9y agoThat's up for debate. Facebook and Google use DC in their datacenters to save costs. Azure has a requirement for optional DC power from their vendors and might be using it actively. I think AWS has looked into using DC power as well but isn't using it afaik.
- Obi_Juan_Kenobi 9y agoDo they use higher voltage DC and buck it down, or is it all 12V, 5V, etc. ?
