They are not very good ones. Where do you live Eur or USA or ?? The deus is better quality then the lc is which is why you get better power numbers with it.
Yes, I own them both. I am in Europe.
What do you think about CS650M 650W 80+GOLD to power antminer s3? Would that be ok?
It's probably overkill for just 1 S3. Should you decide to get 2 S3s I would bump up the 650 to a Corsair 850 Gold or an EVGA 1000 Gold. Otherwise even a 500W Bronze Corsair is fine.
