For everyone who is complaining about electricity watch this. This is how power consumption was back during the Litecoin days with Scrypt.
350Watts per 280X at the wall. And you guys are complaing about 100Watts or so. So spoiled kids these days.

All of those GPUs survived thanks to heavy undervolting, and are still mining to this day.
i'm using 7990 and i dont find way to undervolting this gpu.. can u tell me step by step to do that??
