I'm thinking of buying 3 or 4 Antminer S3, but right now I'm puzzled about getting proper power supplies for these.
- Such EVGA 1300 G2 is quite pricey, are there any cheaper alternatives?
- Can 3 Antminer S3 be powered by a single EVGA 1300 G2 without problem?
- When overclocking 3 or 4 Antminer S3, how do you solve the power supply issue with 4 power connections each S3 (since a EVGA 1300 G2 only comes with 6 cables)?
- What's the power draw of an Antminer S3 when running at 250 MHz?
1) yes - but generally it would mean using a server power supply which is louder and less friendly to use in a small setup. THE EVGA 1300 is a great unit at a good price
2) yes, even at ~380W each you are left with over 150W of overhead capacity on the 12V rail
3) either get a good quality splitter or just use 2 connections per unit. AFAIK using all 4 connectors doesnt provide much realworld benefit but might be slightly safer for the pcb traces
4) closer to 380-400W
