Suggestion for good power supply for s3 Huh

thanks

I will use my 2 corsair CX750M that im using right now with 2 S1.

366W S3 without overclock, so no problem if you overclock, you have 750W and a very good PSU like Corsair.

How much W S3 overclocked?? 488W?

As per the datasheet values below, S3 can be overclocked to 504Ghs and further to 554Ghs.
The stock clock speed is set in between 225M and 250M and voltage per chip lies in between 0.72Vand 0.75V per chip (366W/S3).
When overclocking to 504Ghs it will be consuming around 390W at 250M Clockspeed.
And when overclocking to 554Ghs the clock speed might be 275M and power consumption around 488Watts.
Further overclocking may not be possible, everything lies in finding the sweet spot frequency.
Take a look at DC-DC converters, they are a lot in nos, do you have any idea? Even this new chip consumes lower voltage than S1.

S3 Datasheet Values
Voltage(V) | Hash Rate(GH/s) | Current(A) | Total power(W) | W/GH
0.72 14.18 10.40 7.49 0.528
0.75 15.75 12.24 9.18 0.583
0.80 17.33 15.20 12.16 0.702
0.85 17.33 20.00 17.00 0.981

i think is good 554Ghs @ 488watts.... means my fleet of rm1000 psu's can still run two oced S3 ants like they do now with the S1 ants.
