chipless,
I'm not sure if anyone here has seen or used these 2500 watt power supplies other than me, but I have been running them for more than a year and they are rock solid. I would not recommend pushing any power supply at 100%, but I did run three l3+ off of 1 unit for for over a month as a test and had no problems at 240v. I have not tried running anything with them at 120v as my electrical is set up for 240v.

*edit- You will need a heavier power cord to run it than what comes with it from my experience.
