Hello,

With many S9s how do you power your PSUs? via a PDU (HP EO4500) to a 30A 240V outlet or otherwise?

Hi there,

I couldn't find the exact specs on your PDU so it will depend on a few things. What I did find appears to have it rated for 24 amps and up to 240 V.

A rough estimate will be that you can use 3 S9's per PDU on this circuit.

I'll use 1340 for watts and the worst case scenario add 10% so 1474W W/V=A

= 6.14 amps per miner. So 4 miners will put you over the rating on that PDU as it's rated for 24 amps(common)

Now, if you only receive 220V on the line this pushes the per miner amps to 6.7 amps. Which definitely puts you over.

Hope all that helps. Do you know how many machines you want to bring online or what your plans are for expansion?
