OT, but I'm really looking forward to performing a rite of passage--we should at least get badges or something--by making a 220v NEMA 10-30 (3 prong dryer plug) to C13 (female PSU plug) power cord for the 1200w HP server PSU that I'm using to run my Avalon6...
Just out of curiosity, though...
* Has anyone ran into any issues with their dryer outlet not being surge protected? I'm currently dedicating a heavy duty surge protector to my mining rig
* Also, is it true that the PSU will run cooler--how to even tell, I don't know--on 220v vs. 110v?
Although I don't use the 10-30, if your breaker box is properly grounded, and you're using appropriately rated amps per breaker, you shouldn't have to worry about "surge" protectors. I wired up 6-20's, with 10-2 gauge at 220. I just keep my amps about 80% under the breaker threshold. I've lost power a few times in the last couple of months, and a few times it had a "flicker" before going out. At that point, the main breaker for my miners "popped". So, when the power came on, then off, then on, they had no power hitting them. Even at that point, had the breaker not "popped", the psu's should have caught the problem--if there was one. Most psu's are made to protect your equipment in situations like this.
As far as 110 vs. 220, 220 allows you to pull lower amps, which in turn lowers the temp, in your power lines running TO your psu's. I've never worried too much about my psu temps, as they hardly ever get warm to the touch. This includes 2 apw3++, 2 sorcerer, and 2 whatsminer m3 psu's. Even recently on 88°f days, they're pretty cool.
