...was to switch them over to 240v. I'm in an appartment, so my options are limited, but I was able to plugin to the 40AMP 240V outlet for my electric stove...
Where do you find a 240v adapter for the PSUs?
Or did you stay at 120v and use something like this?
Nope. The corsair AX1200 I use automatically switches to 240v, and about %4 more efficient at the higher voltage (their stats, I don't have a 240v amp meter)
