At first I thought my 2nd S3+ was in a smokey environment but it turns out I must have been simply pushing my power supply too hard... Had both of the miners running off of a CX750M and I saw smoke coming from the pci-e port on the psu... So any recommendations for a psu that will run both without catching fire or something...? Probably 1000w at least?
An 850/1000 Gold rate PSU would do just fine for your S3+ units and give you better power efficiency. Some PSUs to consider would be:
- EVGA G2 Supernova 850w or 1000w
*note: There is 1300w version and its about $70 bucks more than the 850w but unless you are planning on getting a third unit, I would go for the 1000w.
or
- Coolmaster V850 or V1000 (850w and 1000w respectively)
*note: The 1000w is only like $10-15 dollars more than the 850w, so I would go for the extra wattage unless you are on a budget.
Both of these recommendations have excellent reviews and should provide a small return in terms of your power bill consumption (assuming you mine 24/7). If you feel rich and want some amazing stuff, look at the Seasonic X series but be prepared to pay a premium for the name / warranty.
P.S. I looked up the CX750M, its only has 62a available on the 12v rail (744w). While not horrible, that particualr PSU is not rated to run with a 96.7% load on it 24/7. Usually most people and myself, would not recommend putting a load on any PSU beyond it's efficiency rating (see:
