Its working, however this damn thing stops hashing every few hours and needs to be restarted
Are you able to connect when it stops mining?
I don't think 1300W is good enough for an antminer, especially when beginners are present.
I'm running 2 different power supplies (RM850 Corsair and Quark 750 Rosewill) and they're doing perfectly. My rig runs at about 1KW (Batch 6) and the PSU doing 2 hashing boards isn't even breaking a sweat (RM850).
I'm also monitoring power to make sure each PSU runs on less than 80% power.
But on to my question: What do you think about the new Batch 6 and Batch 8 miners, with the giant Buck Converter on it? What's the reason for this, and how might it affect efficiency and stability?
1300w EVGA G2 is absolutely fine. Its power is very clean/stable. It even has some leeway for a bit of overclocking and the 10 years warranty on the PSU make this pick a no brainer; If you want the best PSU to do the job, this one is it.
Second picks would be server PSU's since they cost less for the same job.
