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

Just to clarify after reading the fire hazard thread. I am using 2 separate pci express power connectors to power a full rig right now. Should I also power the 12V/GND power connectors on the other end of the M-board? The rigs have been running stable for the past month.

V3M/V2.2H/Corsair 870 platinum, stock settings, about 650W at the wall

I think 2 cables might over load it but if me add 2 more cables to reduce heat up on pci-e cable.
