The site says 2x1200watt power supplies and it's drawing 1500w from the wall. But here is the kicker.. It says 3000w nominal power. So does this machine operate at 2400w or 3000w at any given time? Thanks

The machine will operate at 3000W. The PSUs can do 1200W, but they can be overclocked by 10% which would make them run at ~1320W. This is the power they feed to the chips. The power that they will draw will be 1500W per PSU.

Gotcha! Thanks - so a vanilla out of box sp30/31 will only draw 1200w per pus from the wall. With OC 1500w?

No. The PSUs supply 2600W to the unit, but require up to 3000W from the wall in order to provide that power. They're about 90% efficient.

3000W wall usage
400W PSU inefficiency
2600W SP30 usage

Good stuff - thank you!
