I'd like to caution others before recommending other power supplies be added to the list. A 'great' power supply in any other application doesn't make a great ASIC miner power supply. If it hasn't been tested stable for a few months on a Cube, Blade, Ant.. etc; please don't recommend it. I have gone through 2 other 'quality' power supplies that would do wonders in a PC, that have failed miserably within days at powering a single Cube. A 600w OCZ and a Cooler Master V1000 (1000w) both were not up to the task.
I just ordered 2 CXM750's to quench my thirst for power. Hope to have my Cubes up and rocking in a few days!!
I don't think that was directed specifically at me but in case it was by any chance all the power supplies I posted are
confirmed to work with mining hardware.
The exception being the Seasonic SS-760XP2 which did NOT work with Cubes. Even just a single, which was surprising but as I mentioned it's likely due to a protection issue rather than a lack of power issue. The SS-760XP2 is a beast of a PC level supply.
