Hi guys - since the latest round of H-cards was shipped at .865v, rigs pull significantly higher wattage. I'm seeing signs of connector burn & overloaded power supplies with some customers. Please be safe - if you are overclocking or running a full rig, a 1200 watt supply is probably a better choice.
Keep your rigs away from flammables - remember these are high-wattage devices!
I've been a little out of touch, sorry if this comes late - we don't have these problems at the data center. We use a 10g high strand count copper wire between 12v supply and the metal lugs on the M-board. The length of our power cables is only about 12 inches.
Best,
Dave
