The PSU's data sheet suggests that it only accepts up to 240V. Whether it would actually work at 250V, you're not going to know until it dies prematurely. If you've got a killawatt you could check if its actually giving out 250V or 240ish.
In the future you can get S2 support here or here.
Topic: Antminer s2 psu voltage input? support for 250v? (Read 803 times)
So I currently have my S2 in the garage because its cooler there and I dont have to put up with the noise in my room. I noticed in the garage we have a hook up for 250v. I did a little googling and am still unsure if US 250v outlets are compatible with psu's. Has anyone tried it? (nema l5-30 prong) I can get a adapter that makes the weird 3 prong to the standard US prong, but it'll still be at 250v. I ask because I am debating getting another high powered miner and I would assume using higher voltage with a higher amperage tolerance would allow me to use more miners without blowing a fuse like I would on the 120v 15 amp outlet. (I believe the main argument was EU uses single phase 240 right, but US uses 120 dual phase, one on each hot prong with one ground. Or am I mistaken)
