<p>I am planning on powering up Antminer S7 with dual power supply per usermanual (<a href="https://shop.bitmain.com/files/download/Antminer%20S7%20user%20guide.pdf" rel="nofollow noreferrer">https://shop.bitmain.com/files/download/Antminer%20S7%20user%20guide.pdf</a>) page 4.  It does not say minimum power requirement for PSU1 and PSU2.</p>

<p>Two boards with 950Watt and 1 Board with 850 Watt.</p>

<p><a href="https://i.sstatic.net/3y5F3.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/3y5F3.png" alt="enter image description here"></a></p>

<p>I plan on using regular power mode without over clocking.  So can it be safe to assume I only need 450 Watt per board and 950 Watt for two board will be just enough?  Will it work?</p>

(Asked by: username_0 on 2017-07-13)

I am planning on powering up Antminer S7 with dual power supply per usermanual (<https://shop.bitmain.com/files/download/Antminer%20S7%20user%20guide.pdf>) page 4. It does not say minimum power requirement for PSU1 and PSU2.

Two boards with 950Watt and 1 Board with 850 Watt.

Since we only need 450 Watts per board and 950 Watts PSU1 and 850 Watt PSU2 worked. Make sure you turn on PSU2 After PSU1 as the S7 manual says.
