I need help with my new Antminer S3's and Corsair 750MW PSU's. My PSU does not power up at all, which means the miner does not either. I just got these today, brand new (including PSU) I need help figuring out how to get this to work so I can start mining.... newbie to bitcoin. Power supply is in correct spots..
You need to do the PSU paperclip trick. Check out Corsair's website here:
http://www.corsair.com/en-us/rm-series-rm750-80-plus-gold-certified-power-supply and look at the "FAQ & Support", then "PSU Paperclip test".
That should get you up and running.
